    Bought it for an all day event in case my iPhone needed charging. Didn’t charge my iPhone. Haven’t tried charging anything else yet. Also pretty heavy to be carrying around in your pocket.

    Got this for my son to carry at school. Packaging said it came pre charged and it wasn’t, isn’t as good as some others on the market. Did come in handy during recent power outage for days.

    My previous charger worked better. This only has 1 charge for my Samsung Galaxy S8 plus. I am ordering one direct from Samsung as it's also lacking the fast charging feature.

    Not really 10,000 mah

    I tested this twice 6 times, 3 using fast charging and 3 using trickle charging and once again I've been... Tricked by a false capacity claim on a battery bank. When I was done testing I opened it up to check the battery model and I didn't even need to look it up, right on the battery 6300mah is printed... Unbelievable. So far I've only found 2 brands that don't make false claims, Anker and iniu. The only problem is because they are known to be honest companies they are more popular which means lots of fakes. Another problem with this having way less capacity is the fact that when you use any fast charging method it ends up being less power efficient. It's just the law of thermodynamics. So really it's more like 4500mah.

      Hi Customer

      The technical side of it is complicated, but the rule is simple: the actual capacity of a power bank is about 2/3 of the capacity indicated. The rest disappears during power conversion or is lost during charging, especially as heat. This means power banks with a battery of 10,000mAh or 20,000mAh actually have a capacity of only 6,660mAh or 13,330mAh. This rule applies to high-quality power banks alone. Budget power banks from cheap wholesalers are even less efficient, so they lose even more energy. you may check below link for more very detail information on why.

    It works fine and charges my phone, but it is not high speed like advertised. It took 2 hours just to get 60 percent, so I'm unimpressed
