I really like owning a solid, reliable power bank. There's something about knowing that your devices will be able to recharge over and over while on the go that just puts my mind at ease, whether I'm at home or on the go. The EasyAcc power bank is another great addition to the category, providing fast charging (my Samsung Galaxy S5 went from almost nothing to fully charged in 30 minutes) as well as a few useful features that you'll appreciate.

It has two USB ports, and both will automatically detect the fastest charging speed your device can handle and then adjust accordingly. You can charge two phones at once without any problems in charging time, and the power bank also has a four-light display on top to tell you how much juice is left in the box.

For those who don't get what 20,000 mAh means in real terms, that's enough to charge my Galaxy S5 seven times on one charge. Perfect for a long roadtrip or for an especially battery-heavy day at the office. The power bank itself is about the size of my hand and feels quite solid, but it's light enough that I could carry it in my pocket, but not comfortably. To me the weight feels like around 2-3 cell phones.

I did have a minor issue with the first charger I received, just a small glitch that would sometimes require me to turn the restart the power bank when switching devices, but customer support was kind enough to send me a replacement right away and the new device is flawless. The only gripe I could possibly have is that the power bank takes a while to turn off after being unplugged, and lacks the kind of fast auto-off feature that I sometimes see in other similar models.

If you need a solution to keep your phone or tablet charged all day, this power bank is a great choice. It's small enough to go with you, and holds enough juice to last you a week's charges, easily.
