If there’s one brand on the market that is very well-known when it comes to the charging electronics space then it would have to be, Anker. They’re always innovating on their portable chargers and they also have quite a lot of other brands that they’ve created such as, SoundCore and Eufy, both of which have seen quite a lot of success even though they’ve just been created recently. In this case, we’re talking about the portable chargers from Anker.

This PowerCore II 10,000mAh power bank is basically the latest version of their PowerCore 10000 lineup, with the base PowerCore 10000 being the first charger. The first PowerCore 10000 is a standard portable charger, but this PowerCore II charger is able to offer more powerful portable charging. So let’s take a closer look to see if it’s worth getting.

Power

Power Capacity:

The power capacity of this PowerCore II power bank is 10,000mAh, which makes it perfect for charging smartphones. However, let’s see how much of this power capacity you’re actually able to use, as there’s going to be a loss of power while you’re charging.

3.7 x 10,000 = 37,000 / 5  = 7,400

Okay, so if you’re charging a standard device that isn’t compatible with Quick Charge with this power bank, then you can expect about a 7,000mAh of output power capacity that you can actually use. That said since this power bank does feature Quick Charge with its single USB-A port, and if you’re charging a Quick Charge compatible smartphone with it then that will result in a lower power capacity because the faster the charging speed, the worse the conversion of the power capacity will be.

So if you’re charging a Quick Charge compatible smartphone with this power bank, which you likely will be if you’re getting this charger, then you’re likely going to get about a 6,000mAh power capacity. This is a still a good amount of output power capacity to use for smartphones as you can charge most smartphones to their full power about two times with that amount of power.

Charging tablets with this power bank is also possible, but at the same time, we recommend that you not depend entirely on this power bank to charge tablets. That’s because it’ll take the entire power capacity of this power bank to charge a tablet to its full power. So it’s best to stick to charging smartphones with this PowerCore II.

Devices	Anker PowerCore II 10000(Output Capacity = 6,000mAh)	Phone Capacity	Anker PowerCore II 10000 Left Over Capacity after One Charge # of Full Charges for the Device
iPhone SE	6,000mAh	1,624mAh	4,376mAh Left Over Capacity 3.6 Full Charges

iPhone 6s	6,000mAh	1,715mAh	4,285mAh Left Over Capacity 3.4 Full Charges
iPhone 6s Plus	6,000mAh	2,750mAh	3,250mAh Left Over Capacity 2.1 Full Charges

Samsung Galaxy S8+	6,000mAh	3,500mAh	2,500mAh Left Over Capacity 1.7 Full Charges

Output Charging:

This PowerCore II also takes the minimal approach when it comes to charging, and that’s because the power bank uses just a single USB-A port. The single port on this charger uses Anker’s PowerIQ 2.0 charging tech, that said, this is basically another way of saying that it outputs 18W and that it features Quick Charge. So you can charge Quick Charge compatible smartphones at their max charging speed.

Also, you can charge Non-Compatible Quick Charge smartphones with the USB port, and those devices will be able to charge at a 5V/2.4A (12W) charging speed. Overall, the charging from this power bank is very pin-pointed for charging smartphones for the most part, and that might seem like a bad thing to some as having more charging ports can prove to be useful to charge more than one device at a time.

Of course, this is Anker’s style and we think that the power bank serves its purpose well with its charging power, and the use of one port means that it’s able to have a small form factor.

Input Charging:

The PowerCore II uses a single Micro-USB input port. We think that this power bank should be using a USB-C input port simply because this is one of Anker’s latest portable chargers, and USB-C is now the new standard for many new Android smartphones on the market. That said, the use of a Micro-USB input doesn’t really hinder anything with this charger, it just means that you’ll have to have a Micro-USB charging cable laying around to recharge the power bank.

On the bright side, the Micro-USB input port uses Quick Charge, so you should use a Quick Charge wall charger to recharge the power bank at its max charging speed, as that will result in 3.5 hours full recharge.

Design

Size and Weight:

The ease portability that you’re able to get from Anker’s 10,000mAh power banks is basically on par with the charging power that they have. Even with the power capacity, and powerful charging, this power bank as a very small form factor. With this PowerCore II having a length of 3.8 inches, a width of 2.4 inches, and a thickness of 0.9 inches. The weight of the power bank is 6.9 Ounces.

So the form factor is basically the same as the base PowerCore 10000, as a result, you can fit this power bank into your pocket, or you can hold it without any problems.

Functional Components:

It’s basically what you can expect from using most Anker power banks. You don’t have to press the power button that’s located on top of the power bank to begin charging, as charging automatically starts when you plug a device into the USB port. The most notable part is that there are 8 White LED power capacity indicators on top of the power button, rather than the normal 4 indicators that most power banks tend to have.

Build

Structure and Material:

The build quality of this power bank is another factor that you can expect from, Anker. As this charger is built very well with its structure and it has many etched lines on the body so that the charger is easier to hold.

Tech:

Even if you’re charging a Quick Charge smartphone with this power bank, you don’t have to worry about overheating, as Anker has actually done many improvements with their power banks to deal with heating.

Reliability

This PowerCore II portable charger is meant for those that own a Quick Charge compatible Android smartphone, as the USB port features Quick Charge and the Micro-USB input port also uses Quick Charge, and it’s likely that you own a Quick Charge wall charger if you have an Android smartphone.

You can of course still purchase this power bank for an iPhone and charge it, but you won’t be able to take full advantage of the charging power from both the output and input.

Summary:

Power:

The power capacity is enough to charge most smartphones to their full power about two times. The USB output and Micro-USB input feature Quick Charge.

Design:

Even with its powerful charging, the power bank still maintains a small form factor that can be taken anywhere that you want and can also be placed into a pocket.

Build:

The build quality of this power bank is very good with its structure and there’s no heating even if you’re charging a Quick Charge compatible smartphone for a long duration.

Reliability:

With its powerful charging and mid-range power capacity, this PowerCore II portable charger is going to be most helpful for Quick Charge compatible Android smartphone users.
