Power Bank 50000mAh Portable Charger Fast Charging 22.5W 4 USB 3.0 QC PD4 for iPhone for Samsung, Phone Battery Pack 50000 mAh Powerbank Cell Phones External Powered Banks (Red Upgraded 2024)

Heavy and with the charging cable (that works both ways, both to charge thru the small USB-in plug, and the phone or other device you want to charge in one of the 4 USB-out plugs.) The tiny instruction sheet that comes with it is almost impossible to read and doesn't bother to mention HOW LONG it takes to fully charge. 50,000 mah is a lot, so I expect maybe 5 or 6 hours.There's a small rectangular button that I assumed is for the light (that didn't work) and all it did was show 4 led bars glowing white (which means there's NO charge in the battery- really inverse logic: there should be NO lights if the battery isn't charged.) After I plugged it into the wall-mounted USB charger, it shows 1 Flashing BRIGHT Bar and 3 steady low-light bars all white. None of this matters if it all charges-up and powers my devices.There ARE warnings about keeping it dry and cool and not dropping it because the batteries are fragile, might break, AND THEN NOT BE WORKING. Battery devices like this are also NOT allowed on aircraft, because the batteries might be damaged by changes in air-pressure, to leak and possibly catch fire! >>>Pay Attention to these warnings!<<<I treat it like I would any other delicate instrument or device: WITH CARE!

I own a much less expensive 14,000mAh power bank that was half the price and works much better. Will only recharge my iPhone XR two times from about 20% remaining. 50,000mAh?? No way. Seems to empty very quickly. It also takes forever to charge the unit back up to full strength. Full strength — what a joke!! SERIOUS BUYERS REGRET! Do not purchase this product. In my many years using Amazon, this is my only disappointment! Buyer BEWARE!

I have been using power banks to charge my mobiles since a long time. My previous power bank was already old so I decided to get a new one and I got this. First I was delighted with the design and now I am fascinated with its performance. I now feel comfortable to take it with me everywhere and I now it is always charged regardless how much I need or use it. The charging time for my mobile is always stable and my battery now last longer. I fully recommend this power bank to anyone who wants a reliable source of energy that makes you happy! A real value for your money. By the way, the blue is beautiful

It did charge faster than some reviews stated (36 hrs.) The one I received fully charged in 9hrs. What I like best was the ability to charge my android phone, fit bit and Ipad and still have 3 blue light's on for plenty of power left. Will up date the more I use it. But so far so good and a good buy for the price.

Este producto ayuda a tener energía en las montañas cuando voy de senderismo. Así me mantengo escuchando mi música y el GPS para saber en donde estoy

This takes about 36hrs to charge, at least thats how long it takes for 4blue led lights to stop blinking. Charging power was good, I have a 3500 mAh phone, and my wife has a 3500 mAh capacity phone also, so thats not much draw. It DID charge them pretty fast, mine in about one hour was fully charged from 5%. Same for wifes phone, a lot faster.Battery life really sucked...This "50,000 mAh" battery pack was killed after charging those two mentioned phones once. I had expected a at least a few days of use, but now Im back to charging for the next 36hrs. Why so damn long to charge the thing, its attached to a wall socket fast charger itself? So much for 50000 mAh. No value for the money with this... Remember... for $27 you get what you pay for. Junk.So, having had a previous pack that worked great, get one with LED percentage power indicator. I wouldnt buy this again, or recommend it. In fact Im just going to get another at double the price with those features.Oh...and really, what do I need a light for, my phone light is better. To me, useless featurePass on this one.

I bought this power bank in 2021 and lost it in a trailer fire in 2023.. they last forever. I was able to get 3 full charges out of this usually and with a good charger too lol so... I would recommend it to anyone

I got 2 of these to keep my WiFi hotspot running for longer before I have to haul it to the charger.It works pretty much as advertised, but some parts of the design do annoy me.Firstly the super bright blue LED's are on all of the time while charging my devices and I can only cry about the amount of power that I am beaming into the room where I could use all of that to power my device.Second it tries to be just too damn smart, it detects when the current drawn goes to 0 and turns itself (and the annoying blue lights) off. This is problematic for me since the WiFi hotspot stops drawing power when fully charged and starts drawing again after the battery dips about 10%, I was hoping that this would be able to keep the charge up - I know this is not promised so I was hoping, but it turns off and did not solve my problem.I just use these as general battery banks now, works OK, charges my IPhone twice when it is fully charged so the efficiency is definitely not top notch and the 10,000mAH is is probably being leeched by the LED's and all the clever logic inside.
