Power Bank 50000mah Fast Charging Portable Charger PD USB C 20W High Capacity Battery Bank 22.5W Quick Charge 3.0 with LCD Display External Battery Back for iPhone 13,MacBook and Samsung

This power bank is awesome as a heavy duty way to reliably charge or run devices off USB power for awhile. But with its size comes certain realistic expectations you should have. Charging will take a longer time than smaller power banks because there is more capacity to fill up. It is heavier than your average power bank because this is 40,000mah, not 20ah (20,000mah). There are more battery cells that adds to its weight and likely exceeds that required to bring with you on an airplane.Unlike others who use the micro-USB port for charging, I use the USB C port. On paper it says the USB C port is 3A while the microUSB port is 2A, which is probably why even though it's only a 1A difference every bit counts in charging it faster. But those specs aren't clear on whether they are the same in input as well as output. But, while it is faster from my experience, expect to charge this over night when the battery percentage is low.The first time or times you fully drain it will be the times it will take the longest to get back to 100% or near 100%. I would plug it into the USB C port with a 3A charger and leave it overnight.if you do prefer to use the micro USB port for charging it for some unknown reason, the amperage of the charger will have some effect on the charging speed. If your charger is 1A then obviously it will take twice the time of charging it versus using a 2A charger. So, The best and fastest is USB C because it is 3A so theoretically about three times faster. MicroUSB is older technology and the plug orienation is annoying legacy. Hopefully one day we no longer need that and have moved on to plugs without fighting with its orientation to a port.

I tested out and it work great! Recharging my phone, my wireless headset, and my Nintendo Switch (OLED) really fast. I recommend of getting this portable charger to everyone. However there one thing to keep in mind that if you're gonna recharge the portable charger make sure the USB charger adapter is 110V and up (picture 2). I use the 30v on that charger and it also burn out (picture 3). Make sure you check the label of the charger adapter before plug the charger it self.Recommend of getting this rechargeable adapter device (picture 3), I order this so it can recharge my port faster and it doesn't overheat in time.

Powerful and great for charging more than one device at a time. Is really heavy so I’m not sure that I will take it traveling but useful at home.

very good

I DO NOT RECOMMEND THIS POWER BANK.I wanted to like this thing but I think it has got defective charging hardware/software. In my case I used the USB A ports and 3 foot cables.The power bank would work for a few minutes then turn off then turn back on again. It would this again and again prolonging the charging time. You can see it in action when the charging led INDICATORS of your devices are cycling on/off - if you are charging a phone you can hear the chime of being plugged in go off again and again. After charging for 1 hour my devices would only get a measly 4-5 % and I'm charging only 3200mah batteries.9/28/23This battery pack is still doing the same thing. It's taking quite a long time charging different phones. I've tried an LG G6, Motorola EDGE 2022, and an Samsung J6. All the same malfunction of intermittent charging is present with all of them. The phones would chime as if the charing cables were just plugged In and then power from the battery would cease after several minutes. This would keep going until the devices were unplugged.Do not buy this brand!5/29/24The battery finally failed. Used the USB A port 1.Was charging a phone and the powerbanks gauge read 82%. I thought it would do fine charging a 4500mah phone that had 30% charge left. I came back 2 hours later to find that the phone only got to 64% and the power bank would no longer turn on. I doubt any apps running on the phone would have been able to drain a 50,000mah(advertised) power bank in just two hours.DO NOT BUY THIS POWER BANK.

Good

Didnt realize how big it is. Also its heavy not too heavy to carry in my book bag but if you trying to lug this in a purse rethink that! Plus side is that if you do carry it in your purse you can now use it as a weapon ijs 😆 [update] i loved this thing it powered all my devices with juice to spare however it broke. The usb slots started to sink into the device to the point i couldnt use it anymore. I wasnt rough with it. It stayed in my book bag unless it was on my desk charging. I guess i got a defective one cause I havent had this for a year yet.

I am a flight attendant I have to be moving all the time, this battery is now part of my luggage, it has take me out trouble many times, if because of your work of life style you depend on electronic devices, have one, you will not be dissapointed
