Purchased for a family vacation and this did not disappoint! The charge lasted our whole trip and it was easy to carry. worth the money and it helped our kids as well keeping their tablets charged when they needed it. And I love the compatibility with different charging cables as well.

[Employee of bestbuy] This battery has a 4 led battery level indicator and while i would prefer the led display with a percentage, realistically it serves it's purpose perfectly well. I charged the battery to full and then used it to charge my friend's, girlfriend's, and my own cell phones. It's still at 3/4 light s on the charge indicator. The qualcomm quick charge 3.0 charge port charges my phone at around 2200 mAh which is plenty fast. You usually need to pick between large capacity or faster charging when choosing batteries at this price point but this is a wonderful middle ground, also totally understand how much 20000 mAh really is, my girlfriend's 30000 mAh battery is great for road trips but it's otherwise overkill.

Great for long times in the car or as an alternative to public wall plugs. Great capacity and fast charge works great. Build quality is really solid and doesn’t feel cheap like most battery banks. Honestly one of the better battery banks that I’ve used if not the best.

As you can see in the photo, its charging my buds, smart watch, Tablet, laptop, and still will have enough juice to power up the Galaxy Note Ultra, Nuff Said! I still don't remember it ever being on empty, and i can count the times I've seen the one-light bar on one hand. One word? Quality!

I really like the convenience of being able to travel overseas and use on the plane and waiting at the gates. The time to recharge my phones and iPad was awesome ! Unfortunately the power button got pushed into the unit after only one and in’s half years of use. Fortunately I bought the total tech plan and I will be replacing next week . Overall 9 out of 10 rating.
