Yoobao Power Bank 4400mAh External Battery Review

We recently looked at the Yoobao Power Bank battery. It’s a beast and has a huge capacity that can keep your device or devices going all day long. That Power Bank isn’t the only capacity that the company is offering, however. They also offered this smaller 4400 mA hour battery, and while it is smaller, it has the same great features. In fact, when the power in my home went out again the other day, this battery stepped in and saved the day. Let’s take a look at it.


From the Company:

So here’s a schematic of the battery itself. On one side, there is the USB output. The battery includes a USB and three adapters so that you can use it with a number of different devices. The other side has a micro USB input that is used for charging the battery and an LED flashlight.

On the surface of the battery, find the power button, a simple power indicator, and a battery level indicator. What I like about this design is that it’s quite simple, yet it has a good bit of flexibility.

The battery comes with the battery itself, the aforementioned USB cable, and three tips. One tip allows you to charge and iOS device. Another is a micro-USB which is as close to universal as you’re going to find.

Unfortunately, I quickly discovered that the iOS device adapter is a little bit thicker than the one Apple offers, and therefore, it won’t work with my iPhone, which is currently wearing a LifeProof case that I am reviewing.

A quick look at the top section shows the flashlight and the micro USB charging port. The battery is simple and clean overall.

The side with the USB ports that are used for charging is equally simple.

Here is the battery when the USB cable and the iOS device adapter are put together. I really appreciate the low profile, simplicity, and overall sturdiness of this battery. You don’t need to use the adapter that they send, but it’s great that they include it so that you don’t need to carry a full-length charging and sync cable if you don’t want to.

At 4400 mAh, the battery has a nice capacity without being too bulky or heavy, and, as previously noted, it’s already saved the day once. I expect that this is one of the batteries that will be joining us in Las Vegas for CES 2012. But perhaps the best feature is the price.

The MSRP on this battery is just under $80, but xengadget.com is currently selling it for $49.95. That strikes me as an excellent value and would make a great stocking stuffer.

MSRP: $79.99 now just $49.95

What I Like: Small in size, large when it comes to capacity; Includes battery charge meter; simple design that is simple to use; Includes a flashlight

What Needs Improvement: Nothing at all
