Sunydeal 30000mAh Power Bank High Efficiency External Battery Pack For iPad iPhone Samsung Galaxy HTC LG BLU Sony Nokia Lumia Google Nexus Motorola Blackberry Smartphone Bluetooth Device Tablet Tab

Do not buy this product. I know there are a lot of people here giving it good reviews, saying that they were given the product on a discount to give an unbiased opinion, but the truth is they probably gave them the good batch of power packs. Once the manufacturer got the good reviews they wanted, they probably started cutting corners to save money on making the product. Unfortunately I do not think this is 30000mAh. It only charged my iphone 6 plus 3.5 times. Once I started using it more and more the life of the power pack became less and less. It almost doesn't keep a charge. I guess you get what you pay for. I knew the price and description sounded too good to be true. Plus side, it came sooner than promised. I hope this review helps other people.

This is the second one I have purchased. The first one impressed me so much, and I can always use the stored power. This product performs exactly as it says. It is a quality product, heavy lithium battery, which I am told is a testament of quality. When you get the Power Bank, it will probably be charged to about 75% plus or minus. It will still take at least 8 hours, or overnight, to fully charge. But it holds its charge, and it is ready when you need it. I have used both the charging capabilities as well as the LED. I have both an iPhone 6 Plus and a Samsung Galaxy S5. Both charge very quickly on this Power Bank. I cannot express how very satisfied I am with the Power Bank.

A few months ago (April from Amazom) I purchased the 30000mah battery. We did not have oppertunity to use it till last night when we went camping. We had charged it and it worked fine (recharging my Samsung note). The next day when we charged it up again, it started to melt down and started smoking. Fortunately I was available to unplug it before it caused a fire.I was charging it on a standard usb charger, the same one I was charging my samsung note on and it was fine.When attempting to contact you thru amazon it indicated I was out side the 30 day window.I have also attached a picture.Please advise asap.I wrote the above directly to the company a month ago and the have never responded. Only giVing 1 star because you can not give 0.

Very handy. Good for traveling

Dont waste your time/money, It doesnt charge my tablet, even it makes strange sounds,

Charged my Android 2% in 4 hrs. My husband said it charged his Iphone overnight, but not quickly at all. Will still be something for my husband to use while in the field. I purchased this item at a discounted rate in exchange for my honest review.

According to an article which test this battery, it is a 12626mA battery only, not 30000mA.(...)I use it once and it was quickly empty, may be after around 3 charge with my galaxy note 2.So it looks like it is true and I recommand to buy another one.

Worked great for 6 months then died while we were on vacation. It got regular use but should have lasted for much longer than 6 months!!
