Portable Charger, 6000mAh for iPhone 15 16 Power Bank, USB-C Portable Phone Charger with Fast Charging (20W), Mini Battery Pack for iPhone 15 Pro/15 Plus/15 Promax/Samsung/Huawei Andriod - White

This little gem is perfect for giving your phone battery a fast boost. It charged my Galaxy S21 from 40% to 60% in 10 minutes, then 60% to 80% in another 15 minutes and still had 60% left on the display.* It weighs only 3.4 oz, so it's ideal to carry in your purse or day pack in case your phone gets low.Recharging the pack itself from zero to 100% took 82 minutes - pretty fast IMO.I'm happy with its capacity. It has just enough juice to give my S21 one full charge, from 0% to 100% (but don't let it get that low).**I am concerned about whether it will hold a charge. The procedure to turn it off completely suggests that this might be an issue. And when it's needed, finding a power source to turn it on again might be a problem.It's not for charging your phone more than once, so ignore the complaints from reviewers who think it should. No pack advertised as 5000 mAh or 6000 mAh will. If that's what you want, lug around a heavier power pack with more capacity.But this one is light enough to carry around, fast enough to provide a quick boost, and has enough capacity for a full recharge. I like it.================Note: The S21 fast charges at 9v. Speed and efficiency may differ for phones that charge at 12v.* The phone slows its charging above 60%, and slows more above 80%. A full charge from 40% took 51 minutes.** Details for my fellow numbers geeks:Advertised mAh are almost always inflated. This pack advertises 6000 mAh, which I never believed. Arguably the "capacity" could be what it takes to charge the pack from the wall charger, which I measured at 5157 mAh. That's more than the 5000 mAh that similarly sized and priced packs advertise. I'm happy with that.What the pack actually delivered to my phone was 3928 mAh, which is close to the nominal phone battery capacity of 4000 mAh. I'm happy with that. And it may well have a little more capacity than most similar packs.For the engineers - I measure in mWh and convert to mAh, assuming 3.7v which is how battery capacity is advertised. To charge the phone from 40% to 100%, the pack delivered 8720 mWh at the USB connector, coincidentally using 60% of the pack's capacity according to its display. Extrapolating gives a total usable pack capacity of (8740 mWh / 60%) / 3.7v, or 3928 mAh.

This charger is fantastic. It charged my iPhone 15 Pro Max from 18% to 84% in one hour! I highly recommend this product if you’re looking for something that’s compact and will charge your iPhone battery to at least 80% in a short amount of time. It does overheat a bit, but not to the point that it’s going to damage or melt any items in your purse.

I’ve had this charger for just shy of one year. For almost one year it worked fabulously and then it just died and stopped charging. I guess for around $20 it was worth it? Now I’m back on Amazon to find another one which will hopefully last longer than a year. While it worked it was great- it charged quickly and was easy to carry with me.

I love the size of this charger; it fits in my pants pocket without much bulging. Charging is quick too. It is an excellent value as well. This is my go-to charger when I am traveling. The battery percentage indicator is a nice feature to have too, instead of the four dots on some of charger at this price level.

I bought 2 of these and thought they were the best portable chargers for my trips. I got a lot of compliments and they were great for a few months then stopped charging even though I had always made sure they were 100% re-charged before each use 8-(

Easy to use and I took it with me to Japan. With a small form factor it was easy to carry around in my pocket.Charging it was fast, and also I was able to get my Pixel 6 from 11% to 100% in about 18 minutes, and the little guy still has 34% of juice left.
