Novobeam NBP3000-2P Ultra-Compact Waterproof / Dustproof Portable USB External Battery Pack Charger / Power Bank, 3,000 mAh, Compatible with most Smartphones and other USB Powered Devices, 2-Pack

These are so cool and make great last minute gifts! Very easy to use. Charge like you would your phone or tablet for about 2 hours the light goes from red to green. When it needs to be charged the green goes to red. They are small so will only last a charge or 2 for your phone or tablet each recharge. I keep atleast one handy in my commuter bag for an emergancy. Also work good for DIY projects where you want a light weight usb battery source :)

They work just fine and provide good portable power. My application requires using both charge and discharge connectors at the same time, so a bit more clearance between the two would be helpful as most connectors will not cohabit well in the current configuration.

I ordered a pair of these so I would always have a handy, pocket sized back-up charger for my iPhone 6. I ride mountain bike and generally spend a lot of time outdoor so I wanted a waterproof/dustproof charger. Honestly, I don't see how these could be either. The cap does not fit very tight and it is attached to the charger unit by a little piece of plastic string that looks as if it would break at the slightest provocation, which of course means the cap would be lost. It could only be waterproof while not in use and the cap is attached firmly (questionable). With the cap removed for USB cable attachment, it would not be waterproof. I sent these back for the reasons I just mentioned and also because even using the Apple (OEM new from the Apple store) Lightning cable, the USB end did not make good contact with the USB socket on the charging unit and as a result, the charger would shut off and not charge my phone, which makes it useless. I tried it with several different cables just to be sure, and all attempts ended with the same result. I ordered a different brand and have been more than satisfied with the new, much higher quality unit. The Novobeam NBP3000-2P is a poor quality, poorly designed, and poorly executed unit in my opinion.

okay

great product I bought 2double pks already used one (lifesaver) everyone should get a few i put one in each car for backup the price is Great too!

Nice! Compact package and works very well. The cap makes all the difference for me since I don't have to worry about where I put it. Will definitely buy more.

Excellent value for the money!!

it is only enough for one recharge of your cell
