Review: Cheero PowerPlus 3 battery bank


Cheero sent us out one of their battery banks to look at, and although we don’t accept too many of these since in most cases, they are all the same, this one stood out a little from the rest. A battery bank that not only fits in your pocket that you can carry all over, but can also charge your device multiple times before needing to be charged itself. This means, it would be good for long trips where you may not be near an outlet any time soon. This battery bank is the Power Plus 3.

The Power Plus 3 offers 13,400mAh of power, which is a bit more than most if not all average banks around its size. It contains a Panasonic Lithium ion battery inside so that you know you will have quality performance and not just a cheap knockoff battery that’s going to start losing its capacity after a few months of use.

The design of it is quite simple with rounded sides and slightly smaller than the average wallet you’d place in your back pocket. Although we say in the video below that it weighs around a pound, it was a little deceiving as when we got around to putting it on a scale, it came in at just above a 1/2 of a pound. So it’s not as heavy as originally thought (our video teams almost never “weigh” through any of this before running an unboxing video), and feels just fine in the back pocket.

There are LED lights on the front of the unit that tell you the current charge it has and it takes about 7-8 hours to recharge the unit fully. So you may want to do that while you’re sleeping at night so that it never phases you. With 13,400mAh capacity, we found on average that it would charge the smaller devices (ie, smartphones, media players, etc) around 2-3x before losing it’s own capacity. It all depended on the battery levels of the devices when we began charging them. In our tests, we began charging the devices once they reached anywhere from 5 to 30% remaining.

With tablets, we didn’t get as many recharges since you’re typically dealing with larger, hungrier batteries that need feeding. We got about 1 to 1 1/2 charges out of the Power Plus 3 when using it with an iPad Air 2 and a number of Android tablets. You never truly get the full mAh capacity of the battery bank, so you have to always expect your math to come in a little less around 60-70% of the advertised number.

We didn’t have any issues with it heating to an uncomfortable level of any kind while keeping it in the pocket while it’s attached to a device. This was a plus as we have used some that felt like there were trying to burn a hole to escape from.

There are two USB inputs at the top side of the unit in which you plug your devices into. It only come with one cable, so you will need an additional one if you’d like to charge two devices at the same time. One input is simply 1A (amp), so it’s good for smaller devices such as older phones and media players. The other input is 2.4A, which is good for tablets, power hungry phones and other larger devices.

When you plug a device into it, it will automatically begin to charge. There are no buttons to press and the only button there is used simply to light up the LED lights on the face of it to show you the current capacity level. There is a small microUSB output between the two USB inputs that is used for charging the Power Plus 3–in which you can use the same cable it comes with to do so.

Charging time for the Power Plus 3 itself depends on the source you have it plugged into. If you have it plugged into a wall outlet adapter that supports 2A or higher or a USB 3.0 (or now the new 3.1) port, you will get the fastest charge time. If you choose an older wall adapter that supports less than 2A or a USB 2.0 or below port, you will see a longer charge time.

Our Conclusion

I never thought I was spend so much time talking about a battery. The Power Plus 3 is a great little power/battery bank that lasts longer than most others. This makes it quite efficient, especially since it is so small. The price runs around $35-40, so it may be a little more expensive than a few, but less than some others that don’t perform as well. So this places it in a decent price slot and helps add to the over-all-score we chose to give it. All-in-all, this is a great portable charging solution.
