Great portable charger for your iphone or ipad! Holds the charge a long time and is fairly lightweight. Much better than the cheap portable chargers I have been buying!

Cool device, it is light and can get about 5 phone charges out of it before needing to recharge again. Useful to keep in your purse.

I have the RZ60G-B, which is essentially the same product but pricier for some reason. I bought it for a trip to Costa Rica last Spring and it kept 2 Samsung Galaxy 5s, a Samsung Galaxy S2 tablet and a Kindle charged (usually two out of the four) without having to plug it in after each charge. It's still working great. There are less expensive brands, but the feel and quality of this power bank are the best. It's built like a Sherman tank.

I was having problems with my Mophie PowerPack, and I traded it in twice, until I saw this thing. I read the reviews (that were super good), and now I own it. It has super high output, and long lasting battery life. It literally charged my IPad and my IPhone 6 at the same time and was done within 15 mins! and I could probably charge my phone again if I had to. I bought 3 more for my family members for Christmas. Love it!

This power bank is built solidly and compactly. Previous free power banks easily broke, but this one is built to last. Shake feature is nice - no buttons needed to see charge status

Great product, purchased on sale on BB.com, this product works as advertised. Great 2a output to charge my tablet and smartphone but also works at 1a output to charge my bluetooth headphone.

On a full charge I can charge my Samsung Galaxy S6 Edge from near dead (2%) to a full charge in a little over an hour without use and still have charge remaining on the razor.

Great charger still using after 4 years and still holding up

Purchased this for my son for his trip and it worked great. Still has it 6 months later and it does the job when you need to add juice to your battery.

Use for iPhone 6+ and ZTE max pro charges both completely in about 1 hour 20 min I love this very useful

Me and my husband use these to play pokemon go and it drains our batteries and these work great even when we play it builds the battery :)

Bought this my charge because I was traveling and with an iPhone 6s Plus I got 2 full charges out of it.

I got this to charge my phone wherever. Holds at least 2 if not more whole charges

I like this battery for the size and the capacity but is to heavy for the pocket

The one I picked up did not hold the charge nor did it charge my items.

My son actually bought this portable charger and loves not having to schlep around cords and bulky chargers

Seems like a good idea, but not worth the trouble.

After using for several months, it would no longer hold a charge.
