SINOELE Portable Charger 15000mA Mobile Phone Power Bank External Battery Pack Quick Charger 4.4A Ultra Compact for iPhone,iPad,Samsung.

Holy crap this thing is awesome! I didn't see this too highly reviewed and I'm just blown away impressed. The packaging was so nice that it puts Apple to shame in that category, and the effectiveness, wow! I've had this charge both my and my girlfriend's iPhone 6/6s for a solid 3-4 days straight (charging up often from the red, multiple times daily) and no problem.The charger itself charges WAY faster than expected too. That said, it is about 8 hours, but when you consider it'll charge an iPhone something like 15 times, that's pretty darn good!If you want something for walking around with in your pocket, anything in this mAh range will be very heavy, but the dimensions of this make it totally comfortable to do so (also fits in my camelbak if I'm running around).

Good product so far. Does have the fast charge on one of the two ports which is awesome. Product also came with a nice carry bag, micro usb cord, and sticky suction thing to attach your phone to the battery while it is charging. The included micro usb does not support fast charge, but not a bog issue as i have my own personal preference micro usb cord. Size is also perfect and fits in my hand. I have a GS7 and it works great for it.

My son plays games on my phone when we are out and about and is always draining the battery. The power bank allows him more playing time and me a functioning phone. This lasts about 5 complete charges for my iPhone 5S.

Pretty heavy - heavier than the other one that I have. But this is solid and works for a long time. Charge felt (kinda) slow on my iPhone 7 - but still a 5-star review for the price you pay.

This is a phenomenal power bank. At first, it seemed impractical because it was larger than I expected. However, the build quality is exceptional. Unbelievably fast charge - faster than any of our wall chargers. We use this constantly. Highly recommend this product.

Solves the problem of iphones loosing charge over the day. Charges 2 phones at once. It works well for 4-6 charges. Great product.

As expected.

This is great since you can charge two phones at a time, but a bit heavy and big in size.
