Our Apple issued lightning cable died. She had a good long life by lightning cable standards. RIP. We had even taken precautions to keep the wire from bending, but alas, it was all in vain. So knowing I needed the iPad charged plus a dying iPhone waiting for it's turn as well, I hit bestbuy.com and saw the Apple cables and was set to do in store pick up, but I didn't have hours to wait around for confirmation of pick up. So I went to the store instead. Not a single employee tried to assist me as I stood in the center of Appleland with 3 loud kids, not even when I literally shouted "I need some help over here" as there were NO Apple cords out on the floor. Only Best Buy's Insignia brand. When I saw 10' I decided, fine, I will go for it. Especially after all the glowing reviews I googled on my Samsung phone. (Hint: their phones will charge on virtually any cable you can find so I'm never out a cable for that device.). Purchased the cable (& the 4' model) and plugged in 2 iPads. One was "dead" and one was at 17%. The dead iPad is nearly 2 years old (yay Defender case) and the livelier iPad is just a few months old. Then the fun began as we watched to see if this cable would work or be a dud. (We had previously bought a $5 cable from 5 Below that took about 12 hours to charge the devices.) After 4 hours, neither was fully charged, but the dead iPad was MORE charged than the one that started off at 17%! You guessed it, that was the 10' cable. I've boxed them back up as after 6 hours both were in the 60%s for charging and selected the Apple versions for in store pick up.
Nice try Best Buy. Fool me once, shame on you, but you won't fool me twice. I'm going to go out on a limb and assume that part of the problem is cable length which may explain why even Apple's longest cable is only 6.6', but I honestly expect more for my money. I've lost 5% of power since opening up my iPad just to write this review and this iPad typically goes 4-5 days with steady use before it is charged again. So even though it reached 100% after 8 hours, it isn't a full or true charge, like when you use your car charger on your phone and it isn't always as strong of a charge.
Do yourself a favor and get the genuine Apple cables, they might be shorter and it's like feeding the beast, but why settle for less when the price difference is nearly negligent?
