High Capacity Real 20000mAh capacity charger is more than enough for few days trip which can fully charge your iPhone 8 for 8 times or Galaxy S8 for 4 times(iPhone and type C charging cable not included). INIU Power Bank feature【Smart LED Digital Display】Fashion and latest design for power level display. Real-time and exact status of the remaining power help you easy to control the power operating. The flashlight feature feels random but nice to have. A child could operate this. You just press the power button twice. (No joke it lights up like a horror game flashlight, a little white circle. 😆) IIRC, I read somewhere that the expected efficiency of power banks should average around 80-85% due to conversion losses. At 70% loss, this power bank does not seem to be every efficient (although in my test, this may be due in part to the fact that the phone used is an old one). The best aspect of the PowerCore 5000 is that it hit 19% after 15 minutes, which is 7% above the Miady power banks. There's nothing particularly wrong with this charger, but nothing impressive either. If you got it as a present, you might hold onto it and get a ton of use out of it. If it goes on sale for a deep discount, we wouldn't be against considering it. But at the end of the day, it's low on our list for a reason.It came over half charged. When I plugged my phone in it said 'charging slowly' and that from 60% to full 100% battery it'd take an hour and a half. I'm okay with that. It's just for emergency power when I'm out all day. Some power banks might be capable of wireless charging, and may even be able to do that while providing power to other devices through the USB ports. Just know that the power it puts out will be split between those devices and may not charge any of them as fast as it would solo.

My ancient Mophie retains a full charge for weeks and will recharge to full in about 2 hrs. This old power bank will recharge my Kindle to 100% from near zero in less than 2 hours, still leaving 75% of the charge. Granted it is much much slower with my phone but I'm not sure why a new power bank is taking so much longer than my old tech.
