Portable Charger, 2-Pack 20000mAh Power Bank Ultra Slim Fast Charging External Battery Pack with Dual USB Outputs Compatible with iPhone 16/16 Pro/15 /14/13/12/X, Samsung S24/S23, Android Phone etc

I like these power banks. I own several power banks but they are heavy, I liked how light these are, if I know I will need more power back up I can bring the pair, but if I feel like all I need is just a little boos I can just bring one I don't have to carry the extra weight.I can get almost 2 full charges for my Galaxy S22 Ultra phone with just one of them, so the pair should be able to recharge my phone almost 4 times.The light indicator is a little difficult to see when outdoors, but I can just cover it a little with my hand and I can see the level of charge it has with no issues. If you are looking for a light-weight power bank, this is a great option.

These work great! Using them for a small project and to be honest they are as good as the major name brands.

Our iPhones with iOS17.5.1 unusually get hot and consume a lot of electricity. Hard reset does not help.We hope it will be improved with iOS18, but we couldn't wait until the new OS to come out for I were to go to an offshore vacation. So, we decided to carry these batteries always with iPhones.It took a long time to initially charge the batteries, but, once fully charged, the juice lasts very long.The only caveat is that the USB output for charging external devices (iPhones) unexpectedly turns off and we had to keep checking if iPhones show "charging" and, if not, manually turn on the battery with the push button. This does not happen very often, but it is somewhat annoying.Otherwise, the relatively slim form factor and not-so-heavy weight makes the product a good buy.I put the battery in my jeans front pocket near the iPhone in a belt holster.

Awesome chargers - easy to transport and use

Great battery charge and great price for 2

This lasted for a couple months. Won't charge now.

I didn't realize these don't have an indicator to show how much charge is left. Most other battery banks do so these were returned and different ones with a charge indicator ordered although the new ones will be half the rating. I would have kept these higher capacity banks otherwise.

I bought two packages of these batter packs.On both of them, one of the power bricks stop functioning. The lights wouldn't turn on. They wouldn't receive charge and they wouldn't charge my devices. Luckily I was able to return both in a single refund.Outside of this very concerning and consistent issue, the bricks also have a weird functionality where they are not compatible with some of my electronic devices. I will plug them into a small USB fan and note that the fan will only turn on for a split second before quickly turning off. It appears that these power bricks send energy in very quick pulses, which, while fine for charging your phone, does not work for any form of moving electronics. In order for me to power my fan, I need to use this power brick to charge a different power brick from another company. I imagine this is a waste of energy and is very annoying.One of the port's charges fast-ish. The other port charges slow. I've been told that the slow port is very good for charging vapes and stuff, so I actually enjoy the options.They're very slim, slimmer than most of the other battery packs I've bought. It can fit inside of my tight jean pockets along with my slim phone, charging it as I'm on the go. Or I can have both of them simply side by side in a small pouch in my backpack.Heat has never been an issue.For the price I imagine this is actually pretty amazing. Just make sure to buy two of them so you can refund the broken ones.Edit: About a week after leaving this review, the other two that I had purchased also failed.Keep in mind that this is in inhospitable conditions- a tent where bugs, moisture, And the occasional gust of heavy rain can slip in. During the duration of this product working, it was an absolute benefit.
