5V 2A Power Bank for Heated Vest, Jacket, Stadium Seats, Chair, Lightest 10000mAh Fast Charging Battery Pack for USB Heated Clothing, Heated Blanket, Coat, Sleeping Bag

Simply to use.Charges my phone quickly.Holds plenty of charge to charge my phone at least twice, probably three or more times.Useful when I went on a long camping trip and had limited access to electricity.

Recently I lost my power bank onboard a flight. I was looking for a replacement that is lightweight and could handle at least 2 charge cycle for a combination of my phone collections, Pixel 3 and iPhone 8+, 6s and Oppo.First I bought Anker Powercore 20100, it was kind of bulky and somehow it stops in the middle of charges with no reason. I have to push the button on the side to start again. Also, Oppo charged very very slow before it stopped. No fast charge for Pixel. So the next thing, I ordered:Charmast 20000 PD/QC 3.0. I found it lighter than Anker, however, this one ran 3 charge cycle and got down to 50%. Oppo charged better than Anker though.I was thinking of keeping Charmast, since its lighter than Anker and smaller. But then I came to see Okzu 10000 has the same QC 3.0 and PD. So I got this one too to check out.Okzu has worked out the best so far! The unit is so light. Smaller than iPhone, sleek design and as of writing this, I am running my 4th charge cycle. I charged Pixel 3XL twice, one from 38% and another from 47% and it fast charged like magic. I charged Oppo, and it fully charged from 17% and then the unit shutdown itself. Then I charged iPhone 6s from 19% to 100% in about 93 min. And the interesting thing is, it still shows 2 led lights.I guess for <$20 this is the best one worked for me so far. I am going to return both Anker and Charmast. I am leaving a 5 star for this now, and I will adjust the ratings up or down based on how this unit performs over the next couple of months.

easy to charge and holds charge. Have used for stadium hot seat and other things.

very lightweight, not overly durable, but should work well for backpacking. I have an iPhone 14 with a battery at 83% efficiency. It charged it 2.5 times.

Mine is five years old. I use it on average five times a month. Still one of the fastest charge points I got. Even compared to my wall and brick chargers. Both sides are fast. If it is full, it can fully charge my Samsung S24 Ultra from empty. Same for my tablet.

I unexpectedly had to replace my previous power bank and only had a few days to do so. I found this one and decided to give it a chance. This one was on par with the other option I was considering as far as size and power capacity, but really stood out when it came to actually charging a device. The other two options didn't have dual input options for charging the power bank (this one can be charged using usb-c AND micro usb); no quick charging output option at all (this one has USB-A & USB-C quick charge) and they were both more expensive.I thought my previous one charged fairly quick, but this one made me realize just how wrong I was. It charged my phone in 35 minutes (from 56%) and then charged my husband's phone in 45 minutes (from 38% to 95%) and still had plenty of power to spare. I would definitely recommend this charger to others.Pros: Dual input charging, USB-C quick charging out, Thin, lightweight, plenty of power.Cons: None that I found.I haven't had it very long, so as it stands right now, longevity is still the only unknown variable. Based on my experience with it thus far, I don't anticipate any problems going forward. But IF something does come up, I will update this review accordingly.

I have recharged my Pixel2 4 times so far and still have 1 LED (of 4) remaining. Very happy as I will typically have 5 days between resupply on the trail but on the trail, I will have my phone in Airplane Mode and so less battery use per day, so I will have no problems making it greater than 5 days. Great price too, so will buy multiple batteries for successive maildrops, each with a recharged 10000 mAh OKZU battery enclosed with resupply food.Edit- Days later, tried to recharge my phone again. Only 1 LED lit on the OKZU. Phone did not charge at all but the battery began showing 2 LEDs lit. Something unexpected going on. So I recharged my OKZU to full power (4 lights) and then tried to recharge my Pixel2. The power bank would charge my phone using the first USB port to USB-C on my phone. Tried the other USB port. After hrs, phone had not recharged even 1%, despite the Pixel2 screen displaying "Charging" and an estimated "19 hrs to full charge". I reviewed the simple instruction manual. Nothing in it about touching the On-Off button. All 4 LEDs became lit on the OKZU upon connecting the battery to my phone, ostensibly showing the OKZU turned on on connection. What's wrong? I pressed the battery's On-Off button and only then did the phone actually start charging at about 1.5% per minute with a new estimated time to charge of 40 minutes. So even if the OKZU's LEDs light up upon connection with a phone, it appears you must press the On-Off button for it to actually charge the phone. Additionally, simply connecting to the Pixel2 showed the Pixel2 "charging" but at a very slow rate (19 hrs). It took pressing the On-Off button to increase the rate of charge from 19 hrs to 40 min. That is confusing and I don't recall ever pressing that button the first 3 times I recharged my phone. Will keep you updated as I'm a little concerned about being out in the backcountry, crawling into my tent at the end of a long day of hiking, connecting my Pixel2 to the OKZU, only to find my Pixel2 had not recharged overnight.
