    I bought this as an open box and I charged it for 6 hours (charging on the side) then next morning I charged my iphone 8 using the Qi and there is no charge. I even tried my power cord , also no charge, so I returned it. Why the heck will Bestbuy put a sticker in the box saying its functional and no defects when it doesnt work at all? I asked the Geek squad to test and and they said they cannot test it, so I asked for a replacement. The replacement I have to pay the difference in price. Why would I do that when bestbuy just sold me a defective unit? Crap service by best buy.

    I bought an open box or at discount for some other technical reason, well I return it as it wasn't able to charge was slow and the wireless which was my main point to buy it was really bad you needed to place the phone in an exact position on top of charger otherwise didn't charge at all, you have to constantly be looking at it otherwise you waste you time the most minimum movement stop the wireless charge

    Dozens at charity event helped by this product!

    I bought this for my son who was participating in a charity bicycle ride. The ride was an over 500 miles / 7 day ride to raise money for cancer research. He used it 24 hours for 5 days before having to charge it. After that the other riders were trapped in their tents and couldn’t access their belongings because the weather had become so bad that they weren’t allowing any of them access to their belongings. Which of course is where their phone chargers were. Because of the power capacity of this item combined with the wireless charging capabilities my son was able to pass it from tent to tent meaning many of the riders, regardless of what type of phone they had riders were able to communicate with their families

    Charger does not last long and takes a long time to charge. I'll probably return it because it is not living uo to the claims on the box.
