Power Bank Portable Charger - 20000mAh High Capacity with Digital Display LED Screen 2 USB Output & Dual Input External Battery Pack Compatible with All The Phone

It is a good charger, but not great. It is a lot heavier than it looks. I have ANOTHER 20,000mAh charger that lasts longer (battery life) and provides much more charging power. This one charges my iPhone 3 times before being dead, my other one charges my iPhone 6 times before dying...

I'm able to fully charge my phone with this charger at least 5 times . Then afterwards, I would need to charge the portable charger.

I wasn't pleased with this device since I bought because the capacity is not large like declared in the product display. Its capacity is enough only for one time charge my iPad mini and for 3 times charges my iPhone 8. Today, it started to not to charge properly. It shows battery capacity at 80% but it stops charging every 3 minutes. When it stops charging, I have to plug out and in again. But it stops again and again. I cannot use this device in this way. It is a waste of money to buy this device. I suppose I cannot return it anymore because 3 months have passed since I bought this device.

I didn't realize how heavy it was even though I read the product description. :) I wanted to carry it in my backpack when traveling but I need to find something smaller.

As others have said, this can't possibly be a 20,000 mAh charger. I have purchased Ankers and Vinsics in the past and have gotten over 5 to 8 charges on my Android or iPhone. This one gives me two at the best. This is what I would expect of a 5,000 to 8,000 mAh charger.I do love the size and layout but would not recommend it or purchase again. I can buy others that will give me a true 20,000 mAh.

This is 100% not 20000 mah. I’ve had multiple battery packs containing this many mah and this by far dies the quickest. I have an iPhonex. I plugged it in at 37% charge. The block was at 80% charge. My phone is now on 60% and the block is already down to 30%. Previous batteries I’ve owned could give me 5+ charges while this one barely gives 2. It feels nice in hand I’ll give it that. Every other part of functionality is bad.

very go to use it.

Good product
