Pros

  • Uses Quick Charge with its Single Port
  • Has enough power capacity to charge most smartphones to full power at least twice
  • Its slim form factor enables it to fit into your pocket

Most of Anker’s power banks can be described as being quite slim as they do their best to provide a very portable form factor with their portable chargers.

Anker does have their PowerCore Slim 5000 power bank but that’s more on the mini side and the PowerCore 10000 is also quite slim too but Anker has a new portable charger called the PowerCore II Slim 10000.

It’s the second version of their PowerCore Slim 5000 as it has a 10,000mAh power capacity and it also adds some other charging features that the lower capacity version doesn’t have.

Power Capacity:

The 10,000mAh capacity of this portable charger is great for the charging tech that it features.

That’s because this PowerCore Slim II 10000 uses just a single Quick Charge USB port that can be used to charge Quick Charge compatible devices at their max charging speeds.

So if you’re using a Quick Charge compatible device to charge at its max charging speed, the conversion of power from the portable charger and to your device is going to be worse as charging is happening at a more rapid rate.

This is normal and we can’t perceive this as a negative thing.

So let’s take a look at what the average Output power capacity you’ll be able to use.

3.7 x 10,000 = 37000 / 5 = 7,400

1.2 Full Charges

So if you’re charging a standard Non-Quick Charge compatible device with this PowerCore Slim 10000 then you’re going to be receiving a 7,400mAh Output power capacity that you can use.

That said, the main reason that you’re most likely purchasing this Anker portable charger is that of its use of Quick Charge and that can very well subtract 1,000mAh of power capacity from the standard Output of power and leave you with 6,400mAh of power.

That said, 6,400mAh of power capacity that you can use towards charging a Quick Charge smartphone is good.

As most newer smartphones have a battery capacity of 2,500mAh or 3,000mAh, and so you’re able to charge your phone to its max power two times. Considering the size of this portable charger, that is good.

Output Charging:

Of course, the single port on this PowerCore II Slim 10000 is part of what makes this charger worth purchasing.

As it uses a Quick Charge 3.0 port that has a charging speed of 5-6V/3.0A | 6-9V/2.0A | 9-12V/1.5A; this port can charge Quick Charge 3.0 and QC 2.0 devices at their max charging speed.

Also, another important factor of its charging speed is that it’s able to output 5V/2.4A for standard devices that do not use Quick Charge, so if you’re worried that it won’t be able to charge your standard devices too, it will.

Input Charging:

The recharging of this power bank has certain levels and we highly recommend using the highest level when it does come to recharging it.

That said, here are the few different charging levels and how long it can take to recharge the PowerCore Slim 10000.

5V/1.0A USB Wall Charger: 10 Hour Recharge

5V/2.0A USB Wall Charger: 5 Hour Recharge

Quick Charge Wall Charger: 4 Hour Recharge

Overall, it’s best to use a USB wall charger that uses Quick Charge with one of its USB ports as you’re able to recharge this power bank at its fastest speed, which is 5V/2.0A | 9V/2.0A.

Design

Size and Weight:

Of course, the form factor of this portable charger is one of the main reasons that you’re going to purchase this power bank as it has a slim form factor.

It has a length of 5.4 inches, a width of 2.6 inches, and a thickness of 0.6 inches. So this charger is quite short and slim and can fit into your pocket. It weighs 7.4 Ounces.

Also, holding this portable charger while you’re using your smartphone is possible too, thanks to its length being very similar to many smartphones on the market which allows you to stack your phone on top of it. It is indeed a worthy successor to the PowerCore Slim 5000

Functional Components:

Just like Anker’s style, this PowerCore II Slim 10000 has a very minimalistic style. That’s because it has both its Output and an Input port on the same side.

The power button is on the long side of the charger and finally, you can find the four LED power capacity indicators at the top of the charger.

Charging automatically starts when you plug a device into the charger, and the LEDs turn off after a while once you’re device is in constant charge.

That leaves the power button with the function of checking the power capacity that’s left. Also, when you’re recharging the PowerCore, each LED light, lights up to show the progress of recharging and once the portable charger is fully recharged, all the lights turn off.

Build

Structure and Material:

This is one of Anker’s products and just like most of their portable chargers, it has a solid build quality. Sure, the portable charger is made of plastic but has a matte grain finish that makes it easy to hold and all of its parts are held together very nicely.

Also, there’s one side of the charger that has a rubber plate where you would place your smartphone for a better stacking grip.

Tech:

On the tech side, this portable charger is very smooth as there’s no overheating whatsoever.

The only reason that this portable charger would get hot is if you’re outside on a hot summer day.

Reliability

The reliability of this portable charger is very objective as it’s mostly meant for users that have Quick Charge compatible device as it has a USB Output port that uses Quick Charge and its recharging can also use Quick Charge too.

That said, you can of course charge Non-Compatible Quick Charge devices too, but if you’re solely charging Non-Quick Charge devices with this portable charger, then we recommend the PowerCore 10000 for a lower price point and same charging power.

Summary:

Power:

There’s still a lot of power available to charge your smartphone twice even when you’re using Quick Charge power.

Also, the same Port can charge Quick Charge compatible devices and Non-Compatible devices at their max charging speeds.

Design:

It’s a level up from the PowerCore Slim 5000 by keeping a slim form factor and a short one too that allows you to hold it, stack your phone and charge it at the same time.

Build:

Solid build quality with all of its pieces holding strong.

Reliability:

Even though this charger can be used by Non-Quick Charge devices, those that own Quick Charge devices can get the best use out of it, as it uses Quick Charge with its Output and Input port.
