best-3000-5000mah-power-bank-logo-trans

If you’ve read our many power bank reviews, then you know that power banks come in many different shapes, sizes, charging capabilities and of course, capacities. We’re here to show you the best power banks on the lower end of the spectrum that have lower capacities and the small size to take these portables chargers nearly anywhere.

These chargers sit in a range of 3,000mAh to 5,000mAh of capacity that is perfect for everyday use because they’re able to provide just enough power, and some are even able to go beyond just a days use.

Let’s take a look at the best small power banks with capacities to match.

#1: Anker PowerCore 5000

pic-1

Anker is known for creating top-tier power banks and there’s really no exception here with their PowerCore 5000 being the best small power bank. It’s a new breed of small power banks that’s being ushered in with its larger capacity of 5,000mAh of power, that can charge many smartphones twice; some other smartphones can even charge more times.

The charging speed is another aspect that makes the power bank awesome because both the Output and Input are 5V/2.0A. As a result, you can expect most smartphones that are connected to the PowerCore 5000 to charge at their fastest speed. The recharging speed is equivalent to the Output, so you can expect a full recharge within 3-hours. That’s enough time to use the power bank again in a single day.

Of course, there’s the portability, with it being rather larger than most small power banks, it still manages with being super portable and can be taken anywhere. It’s just a bit thicker than power banks of smaller capacities, and putting it into a pocket may not be the best option but it can still be very versatile. When you add in the awesome build and the use of Panasonic battery cells to make the Output capacity very close to its initial capacity, then this small power bank is one the best in this mini area of portable chargers.

Specs of the PowerCore 5000:

  • Capacity: 5,000mAh
  • Output: 5V/2.0A
  • Input: 5V/2.0A via Micro USB Input
  • LED Power Indicators: Three-LED status system
  • Size: 4.2 x 1.3 x 1.3 inches

          #2: Tylt 3,200mAh Power Bank

          pic-1-crop

          There are many power banks that look similar to it but this small Tylt portable charger is great because it provides a better charging experience than its competitors.

          This is because the Output charging is 5V/2.1A, most chargers of its size are much slower at 1 Amp charging. So regardless of what device you’re connecting to this power bank, it’ll be charging fast. The Input charging, also known as the recharging speed is standard, with being 1 Amp but even so, it doesn’t need to be that fast since it has quite a low capacity at 3,200mAh.

          Speaking of the capacity, the power sits it the edge of what these chargers can deliver and with a capacity of 3,200mAh you can expect it to last a single day for most smartphones; possibly even more for smartphones with small battery capacities.

          Of course, there’s the size with it being small enough to easily fit it into nearly any pocket. When we say, we mean Any. This is because it has a really short width and the length is at about 5 inches. Putting it into your jean’s pocket will pose no problems, and you can even put it in your pocket alongside your smartphone; Doing that was thought to be a Slim power bank’s capability, but not for this power bank.

          Specs of the Tylt 3,200mAh Mini Power Bank:

          • Capacity: 3,200mAh
          • Output: 5V/2.1A
          • Input: 5V/1.0A

                  • Enough power to charge most smartphones at least once
                  • Has a very small size that can fit into your pocket easily
                  • Has a flashlight
                  • Great build and keeps working even with repeated uses

                  Cons

                  • Only has 1 charging port
                  • Not meant to charge very high capacity devices

                  #3: Anker Astro E1 5,200mAh Portable Charger

                  It’s quite similar to Anker’s PowerCore 5000, but its size and design are just a bit different. Known to be candy bar sized, the power bank does very well at being one the best small power banks on the market because of its short length and skinny width. As a result, it can fit into a pocket and easily be held in your hand.

                  Then there’s the charging, and it can Output 5V/2.0A charging speed to your devices. This amount of Amperage is enough to charge many smartphones at their max speed. The input speed at 1 Amp is to be expected since it’s quite a small charger. The power capacity does a great job at keeping a great conversions rate, so you can very well charge your smartphone up to 2 times. Some may even do 3 times.

                  The design is one the best aspects since it begins charging automatically and turns off when nothing is connected to the power bank; However, these kind of features are prevalent within many of Anker’s portable chargers, which is a great thing to see.

                  Specs of the Anker Astro E1 5200mAh:

                  • Capacity:            Advertised: 5,200mAh             Real Capacity: 5,000mAh

                          #4: Jackery Air 6

                          pic-1-2-0

                          Slim power banks are paving the way for the small power bank arena. This is because they’re basically flattened versions of the traditional cylindrical power banks that are used. This Jackery Air 6 is a great example of what a slim power bank should be.

                          It basically has the same exact dimensions and weight that any smartphone would. As a result, you can carry this Air 6 easily or simply put it into your pocket along with your smartphone. The user experience with this charger is absolutely straightforward and there’s no way it could be cumbersome.

                          It’s very minimalist design is what makes it very easy to use by having nearly all the functional components on a single side.

                          The power capacity may not be the best with it initially being 3,000mAh but actually delivering 2,500mAh but even so, for its awesome portability and ability to charge a single smartphone to its fully capacity, this slim charger is ready to go wherever you need it to.

                          Specs of the Jackery Air 6 Power Bank:

                                  #5: Viivant Slim Portable Power Bank

                                  review

                                  This Viivant Slim power bank is another one that delivers just a bit more than the Jackery Air 6, in some ways.

                                  The most notable thing about this Slim charger is that it has two charging ports. One of the ports outputs 5V/2.1A charging speed, and the other one Outputs 5V/1.0A. So the max output is 3.1A. It’s VERY uncommon for slim power banks to have 2 charging ports but in this case, you can charge 2 devices at the same time.

                                  Along with its power capacity, you can very well charge 2 smartphones to their max capacity at the same time or you can just charge a single device and get two charges for that one device. That’s because the power capacity of this power bank is rated at 5,000mAh but an Output of 4,000mAh is what you’ll be receiving.

                                  To surprise even further, the Viivant Slim portable charger has Input charging speed of 5V/2.0A and can recharge within 4-5 hours.

                                  It’s not much of a surprise about how this power bank can fit into your pocket really easily or how you can hold it like any other smartphone. It’s more about the powering capabilities, with its 2 Output charging ports and Micro-USB Input having awesome fast charging.

                                  Specs of the Viivant Slim Portable Power Bank:

                                  • Capacity:            Advertised: 5,000mAh             Real Capacity: 4,000mAh
                                  • Output:      Port 1: 5V/2.1A      Port 2: 5V/1.0A
                                  • Input: 5V/2.0A via Micro USB Input

                                          #6: Anker PowerCore+ Mini

                                          pic-1-croppedjpg

                                          It’s always about the amount of power that you can get from a small power bank. This PowerCore+ Mini takes what a mini charger should provide and makes it into a most optimal charging experience.

                                          The power capacity is normal for what these small chargers are able to bring to the table, with 3,350mAh of power capacity. The best part of the power capacity is that it’s very close to the initial capacity since the power bank uses Panasonic battery cells. As a result, you can either get 1 full charge to your smartphones or maybe even a half a charge more.

                                          Charging speed is at the most basic level with it providing an Output and Input speed of 5V/1.0A. Sure, it’s not the fastest charging speed that you can get with portable chargers like these, however, it’s more about the ease of use and portability for chargers like these. Take for instance the functional components and how they’re just on just a single side of the power bank.

                                          This charger doesn’t provide the best in charging speed, but for everything else; like its power capacity, design and build quality, all of those things makes this one of the best small portable chargers on the market.

                                          Specs of the Anker PowerCore+ Mini:

                                          • Capacity: 3,350mAh

                                                  It’s a small charger that has a very similar design to other cylindrical power banks. It stands toe to toe with more known small chargers, so it shouldn’t be dismissed without knowing what makes this RAVPower Luster Mini so important.

                                                  Okay, so there’s nothing truly extraordinary about this charger but just as the PowerCore+ Mini, it takes itself to the limit of what these things can do. It has a power capacity of 3,350mAh and that mostly stays the same with the use of Panasonic battery cells, as they give a better Energy conversion rate and are able to hold onto their capacity in the long-term.

                                                  The charging speed isn’t anything special with the Output and Input delivering a 5V/1.0A charging speed. However, when you have something that’s designed like this and so portable that it can literally be taken anywhere, the charging speed isn’t the most important aspect.

                                                  One the best things that mini chargers can be, is to be as simple as possible. This is definitely true for the Luster Mini.

                                                  Specs of the RAVPower Luster portable charger:

                                                          #8: KMASHI Compact 5,000mAh Power Bank

                                                          For its power capacity shortcoming, the KMASHI 5,000 Compact power bank is one real powerful charger.

                                                          The Initial capacity is at 5,000mAh, however, Output capacity that you’ll actually be receiving will be about 3,700mAh to 4,000mAh. This is mostly due to the charging speed, which is an Output of 5V/2.1A. The Output charging is great because it’s near the Max stand charging speed of 2.4A. As a result, you can expect this KMASHI compact to charge nearly any smartphone at its max charging speed, and even charge tablets at quite a fast charging rate.

                                                          The fast charging speed also goes for the Input as well with it being 5V/2.0A, so you can expect it to be fully recharged in 3 hours.

                                                          The design is where this small power bank does pretty good in because of its oval shape, the power bank is actually easier to fit into your pocket than say, a PowerCore 5000 or an Aukey PB-N37 5000mAh portable charger that have similar designs. All the functional components are on a single side of it for very easy access.

                                                          The build quality on the outside is absolutely solid with it being covered by a rubber folding to make it structurally protected. On the inside, the use of Panasonic battery cells could really improve the capacity through a better conversion rating.

                                                          Specs of the KMASHI Compact 5,000mAh Power Bank:

                                                          • Capacity:            Advertised: 5,000mAh             Real Capacity: 3,700mAh

                                                                  #9: Anker PowerCore Slim 5000

                                                                  review

                                                                  We’ve mentioned other slim power banks within this list, there’s one slim power bank that does a somewhat a better job with its form factor.

                                                                  This is the Anker PowerCore 5000 Slim that may not be as slim as the Viivant or Jackery Air 6 but its design is what makes the experience with it better. One side of the PowerCore Slim is curved and the another side of it is completely flat with a rubber surface which has indented grooves. This makes it possible to stack your smartphone on top of the charger so it’s easier to use your smartphone than ever. The side with the rubber is able to hold your smartphone in place and as a result, you can even make phone calls with one single hand. The ergonomic form factor is what puts this power bank near the top of the Slim category.

                                                                  The power capacity is initially rated at 5,000mAh but that depletes to 4,000mAh of power, as energy is lost during charging. You can still expect 2 full charges for most smartphones. The most interesting aspect are the charging speeds, with the Output and Input both being 5V/2.0A. This kind of charging speed with a slim power bank isn’t very common but then again, there’s the case with the Viivant Slim having two ports. The 2 Amp speeds will give you optimal speed for any smartphone that you’re charging, the recharge of the PowerCore Slim can be about 3 hours.

                                                                  If anything, the PowerCore Slim takes Slim chargers to their epitome with it providing a highly functional design and fast charging speeds. Best of all, you can do it all by simply fitting it into your pocket, along with your smartphone.

                                                                  Specs of the Anker PowerCore 5000 Slim:
