Top customer reviews
Some might say that it would have been better to not have a defective battery - but these things happen, and I find the response to these situations to be very indicative of a companies character. I generally love Aukey products and knowing that they are willing and able to stand behind their products gives me confidence to continue to be their customer.
So, this is a product review, so maybe I should say something of the product.
This is an awesome battery - I have been traveling a lot lately and this battery easily gets me through my typical 9-10 hour flights with juice to spare. My typical inventory is a LG G4 and an iPad. Lately I've added a Nexus 6P - the confidence that not only will I not get bored on the flight, but will finish it with fully charged batteries on all 3 devices takes a great burden off my mind. I hate landing, only to find that I have 8% battery left, and I need to get an Uber and start making calls. This does not happen with this battery, so I highly recommend it.
There is a downside - it's large. But frankly, any battery with this capacity is going to be unwieldy and heavy. Aukey does make smaller ones, and I would definitely recommend one of those if the heft of this model is too much for you.
This bank is heavy though. As heavy as about 3 large/phablets phones. I'm not sure it would be that convenient to take it with you at all times out of the house, but maybe could be left in the car and retrieved only if needed. My needs are different than yours as my phone is always charged. At the same time I would rather carry it with me than carrying a dead phone... It has charged my Note 4 probably over 5x + watch, and other phone before it needed recharge. This thing takes long time to recharge. probably over 12-16 hours.
When i first got it ( i got it because it was on front page of slickdeals) and i was not sure when i or how i would use it. When buying it i figured i would use it few times i go camping and that is it HOWEVER i find my self using this all the time. I have it in my office and i place the battery on my desk and its charging my phone while i am working. If someone calls or texts me i can easily check who is calling and pick up or i can view and text easily. Compare that to when you have it plugged in the outlet it just gets annoying with long cables and having to look for outlet all the time. It is a great product
I'm duly impressed with Aukey's customer support. After posting my original review, they reached out to me to offer a replacement. Definite points for keeping an eye out for bad reviews. What I don't know yet is whether the replacement will suffer the same fault as the original. It seems as if there was a batch of units that had a problem, so if the new ones have the problem corrected, I'll be a happy camper. Like I said originally, this unit worked well when it worked, and I would be quite happy recommending it if the reliability problem has indeed been addressed. I guess I will see soon. . .
This was great when it worked, but the battery now refuses to recharge. I have no clue what the expected lifetime is SUPPOSED to be for these, but it certainly didn't last nearly long enough (about 5 months of infrequent use) for me to give it a good rating. I like the design, and the price certainly doesn't make me expect for it to last forever, but there are certainly better options.
