The battery is supposed to work with any USB power source that is less than 2A.

Unlike other portable battery chargers, the NT120R-B essentially cannot be destroyed or broken

I travel for work, and this battery has come in handy in airports, onplanes, and in hotels

The PowerPak Xtreme is a great rugged battery pack that is truly waterproof.

So getting a compact battery that is 12000 mAh is a huge improvement

battery is dead and would take too long to charge even if it could be plugged into an outlet or the car

Myprevious battery would get quite warm--especially while charging my iPad

The battery was at 35%, not bad

When I want touse my cell phone for internet access on my laptop, plugging in the phoneto the laptop drains the laptop battery, so using this device keeps mylaptop battery lasting longer

the battery is only maintained or just drained more slowly

Upon returning the unit still had an impressive 1/2 battery left

If you have this and your phone battery dies you will at least be able to talk on your phone as you won't be able to dial 911 with dead phone battery but with this charged battery you could

I cannot imagine a more durable,overbuilt, dependable battery

I routinely find myself no where near power outlets and to have a battery of this size is fantastic.

In your hand it feels solid and this battery is extremely durable.

Overall a great battery for throwing in your bag or glove compartment, but not so much pocket-sized, if that's what you're looking for.

Whether it would be indoor or outdoor, this battery excelled in every test, and is why I give this battery 5 out of 5 stars

For now I’m glad there’s a very tough battery pack for my kid to not break and be able to check in from the top of the mountain or deep woods.

I bought my very first portable battery from NewTrent about 3 years ago (the 8900mAh IMP880 (discontinued)), and this new 12000mAh beast was a more than worthy upgrade in terms of capacity, quality, and features, though there are still a few areas for improvement (see the CONS below)

I also like that this battery remained cool while charging
