Best Medium 6,000mAh – 12,000mAh Power Banks

(Last Updated On: December 26, 2016)

#1: Anker PowerCore 10,000 Portable Charger

Yes, we know that you’re probably not surprised and neither are we that the first spot on this list belongs to an Anker Power bank. With that said, Anker is after all on our top list of being one of the best power bank brands on the market and it only makes sense that one of their portable chargers makes it onto here.

Power Capacity

This power bank has an initial power capacity of 10,000mAh and that makes it very versatile even when the Output power capacity is 8,000mAh. So with that, you can still charge most smartphones about 4 times or more. For larger capacity smartphones like the Galaxy S7 and Edge version, this power bank can still fair very well. Even for tablets, this power capacity can do enough to charge them to a well off amount. If you’re charging Mini tablets like the iPad Mini series, then this can charge them to full. However, charging full sized tablets will have them charge about 3 quarters of the way through.

Charging: 5V/2.4A

The PowerCore 10000 only has 1 charging port and it makes the most out of it. We say that because it has an Output port that is able to output 5V/2.4A charging rate. This is the Max standard charging speed before a Quick Charge level of charging speed is reached. So even though this power bank doesn’t have Quick Charge it’s still enough power to charge most devices at their max charging speed. If you’re charging a tablet with this power bank then it’ll be able to charge at its max charging speed of 2.4 Amps.

Even when you’re charging smartphones that are compatible with Quick Charge this will do a great enough job. Overall, for something this small, and having a power capacity that can last for days, this charging speed is bound to make the charging speed exceptionally fast.

Recharging: 5V/2.0A

Recharge time is quite good, and this is true if you’re using a 2 Amp wall charger. Since the max recharging rate is 2 Amps, using a 2 Amp wall charger will be able to recharge this power bank to full within about 5-6 hours. Don’t use anything lower if you don’t want to wait double the time.

Portability

This is a very compact power bank charger because of its very small dimensions and what makes it even more compact is the weight. The length is 3.6 inches, it has a width of 2.4 inches, and a thickness of 0.9 inches. It has a weight of 6.4 ounces. This all means that this can fit into your pocket or you can hold it in your hand while you’re charging and using your smartphones at the same time.

At this power capacity, power banks can either be optimized to be very portable or they can be designed terribly and end up being extremely cumbersome. In this case, the PowerCore 10000 has been optimized regarding its size and weight so all the charging power can be taken anywhere!

#2: RAVPower 10,050mAh Rugged Power Bank

Power Capacity:

The power capacity is that of the PowerCore 10000 and it has just a bit poorer capacity wth an Output power capacity of 7,500mAh. Even though the main attraction of this power bank isn’t exactly its power capacity it still does a good enough job that you’re able to get 4 full charges out of smartphones and you can get a full power capacity for Mini sized tablets. However, if we’re talking about full sized tablets this can charge them about halfway through.

Ultimately, the power capacity isn’t exactly enough for the purpose that this power bank was built for, which is to be a rugged one that you’d take into the outdoors. If you plan on camping in the outdoors for a few days this can be a bit of a stretch to use for its short longevity.

Charging:   Port 1: 5V/2.4A    Port 2: 5V/1.0A

The charging speeds for this power bank are exceptionally fantastic. It has 2 Output ports. One port has a Max Standard charging speed of 5V/2.4A and the other one is 5V/1.0A. The Max Output is 3.4 Amps, so you can take full advantage of charging power that either port has to offer.

However, if you want the fastest charging speed for your device then we recommend using the 2.4A port because the 1 Amp port will offer very slow charging. If you’re charging 2 devices at once, then it’s best to connect the tablet to the 2.4A port and smartphones to the 1A Port. Although, if you’re solely charging your smartphone then it’s best to default to just using the 2.4 Amp port.

We feel that the strongest part of this power bank isn’t necessarily the “Rugged” portion of it, rather it’s the use of 2 charging ports and the ability to charge 2 devices at once.

Recharging: 5V/2.0A

If you’re recharging the power bank with a 2 Amp wall charger, it’ll be able to recharge to full power in about 6-7 hours. Using a lower level Amperage wall charger will result in the recharge time being doubled.

Portability:

Most waterproof, dustproof and a shockproof power banks are larger than just a normal power bank; that’s not really the case here, though. Instead, this power bank is about the size an of a smartphone. It has a length of 4.6 inches, a width of 2.8 inches and a thickness of 0.9 inches. It’s even quite lightweight at 7.4 ounces. You can definitely hold it in a single hand if you’re charging just your smartphone.

Another really welcoming portable aspect is that this power bank has a small hook-able placing where you can place a carabiner on the charger and latch the power bank itself on a backpack.

Specs of the RAVPower Rugged Power Bank:

  • Capacity: 10,050mAh
  • Output: 2.4A For One Port / 1.0A For the Other Port
  • Input: 2.0A via Micro USB Input
  • LED Power Indicators: Four-LED status system
  • Size: 4.6 x 2.8 x 0.9 inches
  • Weight: 7.4 ounces
  • 18-month warranty

#3: Tronsmart Presto 10,400mAh Power Bank

Power Capacity:

It loses about 2,000mAh of power capacity during charging and this results in the power bank having an Output power capacity of 8,400mAh. That’s enough power capacity to charge smartphones about 4 times or more. However, in comparison to some smartphones that have larger batteries, this power bank will be able to do around 2.5 full charges for those.

Tablets, on the other hand, aren’t really designed for power banks like these since the power capacity is quite low. It has an enough power capacity to charge most Mini tablets to their full charge about once. Full-sized tablets will fair about half a full charge. It’s also going to depend on how many devices you’re charging at once since the power bank has 1 USB Output port and a USB-C Output/Input port. Charging 2 devices at once can result in worse Output power capacities because more heat is being generated during charging.

Output Charging:

On the charging speed side, this power bank does a great job. It takes advantage of the newest and most powerful charging technologies that are currently available. This is because the USB Port features Quick Charge 3.0 and the USB-C port can be used as an Outport.

The Quick Charge port is able to output speeds of 6.5V-9V/2A or 9V-12V/1.5A, and these charging speeds are absolutely on the level that Quick Charge compatible devices are able to charge at. If don’t own a Quick Charge compatible device, that’s okay because the USB Port can still default to a 5V/2.4A charging speed and this means that Non-Compatible Quick Charge devices are able to charge at their max charging speeds as well.

Then there’s the USB-C port that can be used as an Output port by only a few users; we say this because you can only use the USB-C port as an Output port if you’re using a USB-C to USB-C charging cable, and of course if you’re using it with a device that charges with USB-C. So even though the charging that this power bank has to offer is very fast, the charging type that is available is quite explicit with providing the highest standard and not necessarily the widest range.

Recharging: 5V/3.0A

Recharging is done through the USB-C port and you can recharge it only with a USB-C to USB-A 3.0 charging cable. Also, the max recharge rate of the power bank is 5V/3.0A and this can only be done if you’re using a Quick Charge wall charger, which will result in the power bank being fully recharged within 5-6 hours. It’s one of the few power banks that requires that you use a Quick Charge wall charger to recharge it as fast as possible.

Portability:

It’s actually quite a large power bank but it’s manageable enough that you can hold it or even place it into your pocket. If you’re up to it at least.

This is because the Tronsmart has a length of 6.5 inches, a width of 3.4 inches, and a thickness 1.1. It’s actually heavier than we thought it was going to be at a weight of 10.4 ounces. So it’s quite heavy and large, ultimately we think that it’s best to just hold it.

Specs of the Tronsmart Presto 10,400mAh Power Bank:

  • Capacity:                 Advertised Capacity: 10,400mAh        Real Capacity: 8,400mAh
  • Output:  5V/1.0A
  • Input: 5V/3.0A
  • LED Power Indicators: 4 LED Indicators
  • Size: 6.5 x 3.4 x 1.1 inches
  • Weight: 10.4 ounces

#4: AUKEY 10,000mAh Dual USB 3.1A Portable Charger

Power Capacity

It doesn’t have the best conversion rate, and what starts out as being a 10,000mAh power capacity initially becomes a power capacity of 7,500mAh. So you can still charge most smartphones about 4 times over and tablets can fair into either a full charge for Mini sized tablets and a half a charge for a larger, full sized tablets.

Even though the output power capacity that we mentioned is pretty poor, it really depends on the way that you’re using the power bank; such as charging 2 devices at once or just charging a single smartphone.

Charging:

This power bank has 2 Output charging ports. One of the ports is able to recharge at 2.1A charging speed and the other port is able to charge at 1.0A charging speed. It has a Max Output of 3.1A and this means that either port can take full advantage of its charging power. With that said, if you want the fastest charging speed, you should use the 2.1A port, as the 1.0A port is slower at charging.

Overall, the ability to charge 2 devices at once is very welcoming as the charging ports are very universal and you’ll be able to charge nearly any devices that are charged through a USB with it.

Recharging: 5V/2.1A

The max recharging speed for this power bank is 5V/2.1A. So if you’re using a  2.1 Amp wall charger to recharge this power bank, it will be fully recharged within 5-6 hours. Using anything lower will result in much longer recharging speeds.

Portability:

On the portability side, this power bank does very well as you either fit it into your pocket or you can simply hold it. This is because the power bank has a length of 3.5 inches, a width of 3.1 inches and a thickness of 0.9 inches. So it’s a very small portable charger, although it is quite heavy at 8.1 ounces which is about half a pound.

Specs of the AUKEY 10,000mAh Dual USB 3.1A Portable Charger:

  • Capacity:            Advertised: 10,000mAh          Real Capacity: 7,500mAh
  • Output:   Max Output: Port 1: 5V/2.1A  |  Port 2: 5V/1.0A
  • Input: 5V/2.1A Via Micro-USB Input
  • LED Power Indicators: 4 LED Dotted Power Capacity
  • Size: 3.5 x 3.1 x 0.9 inches

#5: Anker PowerCore+ 10050 With Quick Charge 2.0

Power Capacity:

So we’re back with Anker and this time, Anker has another 1 Port power bank that has Quick Charge technology. The power capacity starts at 10,050mAh initially and it ultimately dumbs down to about 7,500mAh of Output power capacity during charging. With that said, though, the Output power capacity is going to depend on more on what you’re charging and how fast it’s charging.

Even with a power capacity of 7,500mAh, this power bank is going to be able to charge most small devices like smartphones about 4-5 times or more. The best thing is charging tablets as well, because since you have no choice but to charge a device alone, you’re going to be using the entire power capacity at a very focused level. As a result, this will result in Mini tablets being able to charge all the way through and full sized tablets to either charge halfway or 3 quarters of the way through.

Output Charging:

The main attraction for the PowreCore+ is the usage of Quick Charge 3.0 that not only ensures that standard, Non-Quick Charge devices can charge at their max charging speeds. It also ensures that this power bank is capable of charging Quick Charge devices at their max charging speeds.

If a Quick Charge smartphone is being charged with this power bank then its charging speeds will be the following of, 5-6V ⎓ 3A / 6-9V ⎓ 2A / 9-12V ⎓ 1.5A. It meets the standard of what Quick Charge is supposed to offer. Also, if you’re charging standard devices that don’t charge at Quick Charge speeds, then this power bank can default down to 5V/2.4A and this can result in those standard devices being able to recharge their max charging speeds.

The main attraction and overall benefit of this power bank are that it has it uses Quick Charge 3.0 and it’s basically universal with charging speeds that it’s able to provide.

Recharging: 5V/2.0A – 9V/2.0A

What we found strange when we reviewed this power bank is the slight difference it has with its recharging in comparison to similar power banks. It can charge at either a 5V/2.0A charging speed and a 9V/2.0A charging speed. This is why we recommend either using a 2 Amp or a higher charging speed wall charger.

This can make the power bank be able to recharge within 3.5 hours. Yeah, that’s a very fast recharging power bank!

Specs of the Anker PowerCore+ 10050 With Quick Charge 2.0:

  • Capacity:            Advertised: 10,050mAh             Real Capacity: 7,000mAh
  • Output:     PowerIQ – 5V/2.4A       Quick Charge: 5-6V ⎓ 3A / 6-9V ⎓ 2A / 9-12V ⎓ 1.5A
  • Input: 5-9V/2.0A via Micro USB Input
  • LED Power Indicators: 10 LED Power capacity indicators on the power button
  • Size: 3.8 x 2.4 x 0.9 inches
  • Weight: 8.3 ounces

#6: RAVPower 6,700mAh Power Bank

Power Capacity:

So far on this list of best power banks, we’ve got quite a few power banks that have 2 charging ports, however, we’ll now introduce some power banks that have just a single port.

This RAVPower portable has an initial power capacity of 6,700mAh and that becomes 5,000mAh of power capacity if you’re using the power bank at its full charging power. So this doesn’t meet the same power capacities as the other power banks on this list but that’s not a bad thing. This is mainly because this power bank is quite smaller.

So the power capacity is mainly meant to charge smartphones and it does well enough with providing 2 full charges to most smartphones. As for tablets, well, this isn’t the kind of power bank that you’d charge a tablet with. However, if you did, then it’d do about 3 quarters of a full charge for Mini sized tablets and a half a charge for a full sized tablet or maybe even less than that. The main thing to remember with this power bank is that the power capacity is going to last either 1 or 2 days of use. It’s much closer to that of a Mini sized power bank regarding its power capacity and size.

Charging:

Even though the power capacity isn’t exactly that high, the way you’re able to utilize it is really good because it has a Max standard charging speed of 2.4 Amps. You can charge any USB charging devices at their max charging speeds, although that’s excluding those devices that are compatible with Quick Charge and USB-C since those devices charge faster under certain technologies. With that said, if you’ve got a standard device then this power bank will be able to charge it at its max charging speed.

This stands very true for tablets that have a Max Standard charging speed 2.4 Amps and even though this power bank won’t be used very much with tablets, the charging power is still there at hand.

Recharging:

Recharging is very standard as you’ll be able to recharge this power bank at a charging rate of 5V/2.0A and if you’re using a 2 Amp wall charger you can recharge this power bank to its full power capacity in about 4-5 hours.

Portability:

The most noticeable aspect of this portable charger is just how small and light weight it is. It has a length of 3.5 inches, a width of 1.6 inches, and a thickness of 1 inch. It’s also quite lightweight at 4 ounces. Yes, it can fit into your pocket but ultimately the thickness is so great that you can’t fit this into your pocket along with your smartphones. Also, we highly recommend fitting it into your back pocket as it’ll be easier for mobility.

However, we found that simply holding this charger is the best option if you want the easiest user experience.

Specs of the RAVPower 6,700mAh Power Bank:

  • Capacity:            Advertised: 6,700mAh             Real Capacity: 5,000mAh
  • Output: 5V/2.4A
  • Input: 5V/2.0A via Micro USB Input
  • LED Power Indicators: 4 LED Power Capacity Indicators
  • Size: 3.5 x 1.6 x 1 inches
  • Weight: 4.2 ounces

Review: RAVPower 6,700mAh Power Bank

#7: Zendure A2 Power Bank

Power Capacity:

The power capacity of this Zendure follows close the RAVPower portable charger in that it starts with a power capacity of 6,700mAh and that can go down to 5,000mAh of available power. This results in this power bank mainly being used to charge smartphones as most smartphones have lower battery capacities than this and they can get about 2-3 full charges.

Using it with tablets is a little bizarre as this power bank will charge even Mini tablets up to half way or possibly a bit more than half a charge. Charging full sized tablets will definitely make them charge only halfway and most of the time, even less than that.

Ultimately, this power bank is meant to be charged with lower capacity devices, because that way it can be used multiple times before it needs recharging.

Charging:

Most power banks with this design should have a fast charging speed and this stands true with Zendure’s charger as well. This Zendure portable charger has a single charging port that offers a max charging speed of 2.1A and this is enough to charge most smartphones at their max charging speeds. It comes close to reaching the max charging speed for tablets which is 2.4A, but that’s alright since charging a tablet with this power bank isn’t such a good experience anyways.

With that said, if you plan on charging small devices, they’ll be able to charge at a very fast charging speed.

Recharging:

The recharging speed is pretty good but it doesn’t push any boundaries. We say this because this power bank has a max recharge rate of 1.5A. Even though it’s within the 1 Amp range, using a 2 Amp wall charger is your best bet to charge it at its max recharging speed. With a 2 Amp wall charger, you’ll be able to recharge fully within 4-5 hours.

Portability:

On the portability side, this portable charger is indeed portable enough to be taken nearly anywhere. This is because it has a length of 3.7 inches, a width of 2 inches and a thickness of 1 inches. It’s really small and fitting this into your back pocket should pose no problems. On the weight side, it’s really light at a weight of 5 ounces. With the dimensions and weight combined, this has nearly as much easy portability as a Mini power bank does; plus you get the power capacity and powerful charging of a power bank.

Specs of the Zendure A2 Power Bank:

  • Capacity: 6,700mAh
  • Output: 5V/2.1A
  • Input: 5V/1.5A via Micro USB Input
  • LED Power Indicators: Four-LED status system
  • Size: 3.7 x 2 x 1 inches
  • Weight: 5 ounces
  • 18-month warranty
  • Comes With: 20″ Micro USB Cable, Cloth Carrying Pouch, Product Manual

#8: Anker Astro E3 Ultra Compact 10,000mAh Portable Charger

Power Capacity

Bring it back to Anker one last time on this list. This is the Anker Astro E3 portable charger. It’s one of the best because of all its facets, and this is because none of them are mediocre and all of the parts of this portable charger have been near optimized for their potential.

The power capacity starts at 10,000mAh and during charging the Output power capacity goes down to 8,000mAh. This amount of power capacity is plenty for charging smartphones multiple times and it’s even enough to charge Mini sized tablets like the iPad Mini 1 and 2 versions near or at their full battery capacities. Full-sized tablets will be able to achieve about half of their battery capacities.

This power bank even has 2 charging ports, so you can potentially charge 2 smartphones to their full power capacities at the same while still having more power left over to use later.

Charging:

Anker likes to create quality products, it’s in their nature. This is why we absolutely love the Output charging capabilities of this power bank. Each of the 2 ports is able to Output 5V/2.4 Amps, which the Max standard charging rate. With that, you can charge most smartphones that aren’t compatible with Quick Charge at their max charging speeds. This is especially true for iPhones. You can even charge tablets at their max charging speeds, but only if you’re charging the tablet alone, and this is because the Astro E3 power bank has a Max Output of 3 Amps that is shared by both the charging ports.

So connecting another device while a tablet is charging will make the same current go to the other charging port. With that said, though. A shared charging speed in the case of charging smartphones is an overall better option because this way, the 2 smartphones that are charging at the same time will be charging at their max charging speeds. Rather than 1 port being 2.1A or 2.4A and the other one being 1 Amp; this power bank takes a more equivalent path that provides fast or at least standard charging for 2 devices charging at once.

Recharging:

By using a 2 Amp wall charger, you can recharge this power bank at its max charging speed and it can fully recharge within 5-6 hours.

Portability

The portability with the Astro E3 is one the best parts of the power banks other than the charging speed. It has a length of 5 inches, a width of 2.6 inches and a thickness of 0.65 inches. It’s nearly as small as a smartphone if you’re not counting the thickness of it; and if even if you are counting the thickness, this power bank can easily fit into your pocket, probably not with your smartphone but it can fit alone into a pocket very easily.

Holding it won’t pose any problems either because it only weighs 8 ounces.

Specs of the Anker Astro E3 Ultra Compact 10,000mAh Portable Charger:

  • Capacity:            Advertised: 10,000mAh             Real Capacity: 8,000mAh
  • Output:   Max Output Per Port: 5V/2.4A     Max Output Overall: 3.0A
  • Input: 5V/2.0A Via Micro-USB Input

#9: Zendure A3 Portable Charger

Power Capacity:

It has a starting power capacity of 10,000mAh and that goes down to about 7,500mAh. We know that’s quite a drastic change but it’s still quite a lot depending on what you’re charging this power bank with. We say that because it’s best to charge this power bank with smartphones because it can charge most smartphones about 3-4 times or more for smaller battery capacity smartphones. It’s not the best power bank to charge a tablet with, but if you were to charge it with a tablet then you can charge Mini ones about to their full capacities or at least close. Full-sized tablets won’t fair too well with this Zendure power bank’s battery capacity as they’ll be able to charge only halfway through only.

Charging:

On the charging speed side, the Zendure A3 portable charger takes the same charging design that Anker has with the charging speed through each of the ports. Either of the 2 ports can Output 5V/2.1A, but then there’s the Max Output of 2.1 Amps. This means that the power bank can only have a Max Output of 2.1 Amps at any one time.

It’s lower than the Astro E3 that is also on this list but even so, we’re in full support for a power bank that has a shared charging current for its charging ports because it allows any device that’s connected to the power bank to charge either at its max charging speed or at a good enough charging speed.

Recharging:

The recharge rate sits at 5V/1.5A, and by using a 2 Amp Wall charger you’re able to recharge the Zendure A3 to its full power capacity within 8 hours.

Portability:

For its power capacity, and charging features, the design for this A3 is really amazing as you can easily hold it and you can even place it into your pocket; a lot of that can’t be said about most 10,000mAh power banks because some power banks haven’t reached that standard yet. With that, the length of the Zendure A3 is 3.8 inches, it has a width of 2.5 inches, and a thickness of 1 inch. It’s also really lightweight that makes it even better to hold and stay on you along with its small size with a weight of 7.2 ounces.

It brings a full power bank charging experience that takes versatility and power, combines it to make it one of the best Medium 6,000mAh – 12,000mAh power banks.

Specs of the Zendure A3 Portable Charger:

  • Capacity:            Advertised: 10,000mAh            Real Capacity: 7,500mAh
  • Output:   Either Port: 5V/2.1A    Max Output: 5V/2.1A
  • Input: 5V/1.5A Via Micro-USB Input
  • LED Power Indicators: 4 LED Dotted Power Capacity Indicators
  • Size: 3.8 x 2.5 x 1 inches
