I travel for work and keep destroying other battery packs. All it takes is for the cap on a bottle of water to leak and the pack never works again. I was so happy when I found this one! It's still going strong and I take it out on my boat and camping too. Great product

This charges my Android from ZERO 4x . The battery pack itself takes about 2-3 hrs from zero (depending on the current) . Other than that it travels well without the added weight im my backpack. This can last me a week when fully charged

It is very sturdy being waterproof and protects itself when dropped. It charges my phone a few times once it's full - but it takes forever to charge itself, hence the four stars.

I’m loving this product. I originally bought this for my girlfriend but eventually purchased another one for our children because they kept using hers!! It charges our devices surprisingly fast!

Great battery, very durable, nice holder to keep handing when traveling around. Only bad thing I can say is its very big and heavy. But if you are out and about it's a great item to have to charge all those portable devices.

We always buy these for our cellphones. If we are traveling we trust charging our phones a lot more than plugging them into a strange place that could be hacked.

This portable charger is the best one I’ve ever owned. Charges fast though a little bulky to personally carry around it’s still good to keep at a stationary area for charging and charges in half the time as any other charger I’ve owned

I’ve been using this for a couple of months now. I’m able to completely charge my phone at least 4 times in a work week. I’m gone for over 16 hrs and being able to charge my phone while at work is great.

This bad boy keeps my Clash addicted friend going for hours after he fails to charge his phone during any of his frequent naps he has to take between work and happy hour. I even use it sometimes.

Does what it says. Took this on a Caribbean sailing trip. Held a charge and was able to charge two phones a couple of times with it. Although it was not completely charged out of the package, only had about 75% charge

We bought the portable charger to keep are phones and any other devices we had on us when we went to the parks in Orlando, FL. It works great it helped keep all are devices charged throughout the day.

Have used this frequently on vacation....holds a charge extremely well...went on a 3-week vacation and never had to recharge the unit....used it several times

Very heavy and bulky but lasts a long time. Its great for deployment or long travels in and around the city

This is the second of this brand I have bought. It charges quickly, does not get hot and is easy to use. I highly recommend this product.

Killer charger especially for when it came out initially. Throw it in the lake? No problem.

Downside- heavy Positive- charges several units. Fast charger. Does an excellent job. Shuts off automatically when the unit is completely charged

We got this for traveling and its been through the ringer! Works really well still

EXCELLANT product for a teenager with a older car so they will never be without a charged cell phone.

I have had other types that were worthless. This works great. Does what it is advertised to do. Worth the price.

One of the best power packs out there, this unit, brave the northern reaches of Canada, and supplied a iPad and a iPod for a week in the wilderness
