Every time Anker releases a new charging electronic, we’re going to be interested and the main reason for that is because they’re a brand that creates some of the best charging electronics on the market. Especially when it comes to their portable chargers, that’s because Anker’s power banks are some of the best-selling on Amazon.

One of Anker’s latest portable chargers is their PowerCore II 10000 that is very similar to their other chargers such as the PowerCore 10000, and PowerCore+ 10050. That said, this PowerCore II 10000 portable charger is a lot more versatile with its power and it still holds a very similar form factor than its similar chargers.


Power Capacity:

The power capacity of this PowerCore II 10000 portable charger isn’t anything special but it’s also what makes Anker’s 10,000mAh power banks so great. As this charger and the ones similar to it have just a single port and so the power capacity is going to be focused to just a single device. Also, when it comes to the PowerCore II 10000, the Output power capacity that you’re actually able to receive is going to change depending on what device you’re charging with it. That’s because it has a charging power that can charge quite a bit depending on what device you’re charging with it.

If you’re charging standard devices with this portable charger then you’re most likely able to get about 7,400mAh of Output power capacity that you can actually use towards charging your devices. This is great for most smartphones as you’re able to charge most phones to their full power about two times. That said, if you’re getting this PowerCore II then you’re likely not going to just charge standard devices and instead, you’re likely going to charge a Quick Charge compatible device with it or devices that can take up to 18W of power.

If that’s the case, then the Output of power that you get from this power bank is going to change as a faster charging speed actually worsens the conversion and as a result, you’re likely able to get an Output of 6,000mAh of power capacity. This is still a really good amount of power for charging smartphones and that’s what this charger is really meant for doing.

Output Charging:

The Output charging speed of this PowerCore II 10000 is its most important part and that’s because it uses Anker’s PoweriQ 2.0 tech. It’s really fancy term of saying that the single port on this portable charger is able to output 18W of power and that is really good because you’re able to charge the more powerful devices on the market at their max power and the devices that we’re talking about are ones that use USB-C but don’t use Quick Charge. Anker does state that this portable charger cannot charge some USB-C smartphones at their max power which includes the Nexus 6P and the Nexus 5X.

Another charging tech that this PowerCore II 10000 features is Quick Charge, in a way. As it has a potential output charging speed of 5V/3.0A | 9V/2.0A | 12V/1.5A and those are basically Quick Charge speeds to charge Quick Charge compatible devices at their max power.

Overall, the charging power with its single port is very capable of charging many different types of devices at their max power whether its standard charging USB-C devices, Quick Charge compatible devices or any other devices that can charge through a USB connection, we really like what Anker has done with their PoweriQ 2.0 technology as it’s a universal way for delivering faster charging speeds.

Input Charging:

The input recharging speed for this PowerCore II 10000 is another strong charging feature for this portable charger and that’s because it uses Quick Charge with its input port. It uses a Micro-USB input port and if you want to recharge this portable charger at its max recharging speed then you should use a Quick Charge USB wall charger.

Using a Quick Charge USB wall charger will result in a full recharge within just 4 hours which is very fast when it comes to a 10,000mAh power bank.


Size and Weight:

The size and weight of Anker’s 10,000mAh power banks are one of the best parts of them and it’s the main reasons that they sell so well.

This PowerCore II 10000 measures at a length of 3.8 inches, a width of 2.4 inches and a thickness of 0.9 inches. The weight of the charger is 6.9 Ounces. So it’s very easy to fit into your hands and charge your smartphone while you’re using it. Its thickness might be a little too much for some that want to place it into your pocket but it’s completely possible to fit this charger into your pocket without too much discomfort.

Functional Components:

On the functional side, this Anker PowerCore II 10000 is very easy to use and it takes the minimalistic route just as Anker’s other portable chargers have, with side things such as a flashlight.

On the side of the PowerCore II 10000 is where the USB Output port is and next to the USB port is where the Micro-USB input port is. The USB port is colored Blue to show that it uses Anker’s cooling technology.

At the top of the charger is where the power button is and it has 8 LED lights on it. With there being eight lights for indicating the power capacity, you can basically assume that each of the lights stands for 12.5% of the power that’s left in the portable charger. The power button itself is really only used for telling how much power is left on the power bank as the lights turn off during charging.

Speaking of charging, charging automatically starts when you plug a device into the USB port and charging stops once there are no devices connected to the charger.


Structure and Material:

If you want one of the best build qualities when it comes to portable chargers then you can’t go wrong with Anker. As this PowerCore II 10000 portable charger has a solid build, even though most of it is made of plastic, the way Anker constructs their chargers is done really well as there are no loose or cheap feeling parts at all.

Even when it comes to using the USB ports, this charger does a great job at holding on strongly to the cable to make sure that it doesn’t get loose and that is a good thing as you can move and not have to worry about your cable coming out.

Perhaps the only negative part of the build quality is the panel where the USB port is, is that it’s protruded from the base of the charger rather than being flushed.


One of the things that Anker has gotten right with their most recent portable chargers is the heat management and when it comes to this charger there’s not very much heat even when you’re charging a Quick Charge compatible device.


Overall, this PowerCore II 10000 portable charger is a great charger with quite a good amount of power capacity to charge most smartphones their full power twice. Its main highlight though is its charging output as it has a quite a lot of levels of charging for standard devices and devices that use Quick Charge too.



It’s a portable charger that’s mostly meant for smartphones and the charging power is great for a plethora of devices. When it comes to recharging this portable charger, it uses Quick Charge and you can use a Quick Charge USB wall charger to recharge it at its max charging speed.


It’s a very small charger that can fit into your hands very easily and has a very minimalistic design too.


The built quality of this charger is top notch and it one of the best on the market, although it would have been nice to have a flush panel where the USB port is.


It’s a highly reliable portable charger that you can find useful for various devices and when you add in its extremely small size that you can go anywhere with, it’s a reliable charger.
