Sunydeal 30000mAh Power Bank Universal External Battery Charger For iPhone iPad Samsung Galaxy HTC LG Google Nexus Blackberry BLU Lumia Moto ZenFone and other Cell Phone Tablet

Don't waste your time, this is a piece of garbage. After about a week of very light use this stopped outputting any charge to whatever is plugged into it (phone, tablet, etc). When charging the power bank itself all the lights flash as if it is charging up, but when you go to charge anything with it it does not output a charge nor does the light come on which is how I know its not charging itself even though it looks like it is.

My husband is on his phone all day, every day, and only sleeps for 5 hours a night, not giving it much time to rest and charge. To test out this battery bank, he used it to charge his phone instead of the wall charger. He was able to fully charge his phone, while he slept, for a full week before needing to charge the power bank. Success! He drains batteries on phones so quickly, he needs to charge it during the day often. This is the answer. It's slim and light weight, so it's easy to take in his tow truck with him. At one point, the power port in the truck went out and he used this to power the laptop in the truck for the night. I highly recommend this product.

Not really happy with this product so far. Worked great the first day as they came fully charged. Once we charged some devices and the battery power went to zero, the problems began. I purchased two of these as we have three kids with many devices, not to mention my wife and my devices as well. The first unit would not recharge at all. The input plug is very touchy and only seems to work if held a certain way. I have returned one unit and am giving the second unit a chance before I send it back as well. Right now if I bend the cord and use a very large binder clip to hold the cable a certain way....it seems to re-charge. Time will tell....but it seems to be the same old saying...you get what you pay for.

A good bargain for the money. The light works great. I usually only use the 2.1 Amp port for charging Android devices but have charged my tablet and phone at the same time and still had plenty of power to spare. If I only use it on my phone I can charge it more than 10 times from completely dead.

It has 3 ports for charging, but it you put more than one item on it to charge it will shut down amd stop working.

Works great. Had another brand that lasted about a month. This one is 6 months old and going strong!!! Love it...!

Worked so well my son took it! smh

Straight out of the box i charged my phone 6 times still had 1 bar left of 4! Sucks it takes so long for the charger to charge but so well worth it!!! Bought 2 more for back ups on my trip to south dakota on a motorcycle from chicago.. only used one there and back never even charged the charger! Little bulky wiah could be smaller but again definitely worth it!
