Portable-Charger-Power-Bank - 50000mAh Powerbank PD 30W and QC 4.0 Fast Charging External Battery Pack with USB-C LED 4 Outputs & 2 Inputs Portable Charging for iPhone 15 14 13 pro, Samsung

This is my second purchase of this product. I bought a different brand at the same time I bought the first one of these and the other one failed and this one is still going strong. I need 2 to alternate between to use with my insta360 cameras to allow longer recordings. I sometimes have to ride 2-3 hours and an insta360 battery would not last that long. I've used it to charge other devices as well. I charge it using the USB-C port and it charges quickly considering how much power it stores. I would recommend this if you need a reliable power cell.

This is a life saver..I love the fact that I am able to charge multiple devices and it does so quickly..Additionally the power bank itself can go about 2-3 days before needing a recharge..It is very bulky and heavy in comparison to other power banks but I honestly don't mind especially since it is so efficient.

great product would recommend, haven’t tested its heat protection much but it’s been better than any anker at the same price over the last month

It works well, but it is quite bulky and heavy so we returned it.

"This thing WORKSIt does have some weight to it. But it charges super fast and holds a good charge for dayssss. It is durable and flashlight is pretty bright for a small design. We had bad weather a couple months back and I ordered right before storm hit. I had no power for 3-4 days the battery lasted 2.5 days charging my iPhone, small portable fan, and some co workers phones before I could get to a generator to recharge it. Has multiple ports including C chargers port"

The product is built well and seems very solid. It does take a while to charge which I get. My only complaint so far and I noticed another user has also mentioned this but it is not 50,000 mAh. I did test this and this is what I found. (I also bought 2 of these and both were the same)Control test:I have a portable power station (solar generator) which is 299wh (around 80810 mAh). I have a set of usb string lights (5v) If I plug my string lights in to the power pack it says it should run for about 60 and yes I let it run. If I take 299/5 it comes out to 59.8 so pretty close.Power Bank:"50,000 mAh" so it says if you do the math that should come out to roughly 185 Wh. When I took the same lights from the control test and plug them in I was losing about 7% an hr. (yes I tested with a stop watch) I did let it run till 0 and it only ran the lights for about 14.5 hrs. Problem is if you take 185/5 It should have been able to run the lights for around 37 hrs. As another user has mentioned he was thinking more around 20,000 mAh so if I do the math with that number here is what I get.20,000 mAh comes out to about 74 Wh. So if I take 74/5 that comes out to 14.8 hrs. That is a lot closer to what I witnessed running my 5v lights off this power bank. Hopefully Amazon has them change this so more customers are not misled. All in all if they would have put the correct 20,000 mAh in the description I would have rated it higher it is a well built product and works but not for as long as they say it should.Wh = Watt hoursmAh = Milliamp hourshr = Hourhrs = Hours/ = DividemAh to Wh:Formula is (mAh)*(V)/1000 = (Wh)Wh to mAh:Formula is (Wh)*1000/(V) =(mAh)

This powerbank was phanominal and durable. It renaissance chargé for a excessive à moune of time and is efficient to use and is very easy to carry. And is à portable item that can carries in purses and bags to use.

12/16/2024.Tengo problemas con esta Power Baterry, al parecer esta defectuosa, se apaga contantantemente cada unos 15 o 20 Minutos, de forma que tengo que desconectar el cable y volver a conectarlo, y solo estoy alimentando un termo de Insulina. A pesar de estar cargada al full, se apaga, he probado por todos los puertos de salida y siempre me hace lo mismo. Y presisamente la compre porque la necesito. Voy de viaje y necesito llevarme la insulina fria ya que el viaje es de varias horas e inclusive compre otra Bank-Power más de esta. La segunda que compre aun no me ha llegado, espero que no este defectuosa también. Tampoco responde al boton de encendido, a pesar de oprimir el botón de encendido, no hace nada, se mantiene apagada todo el tiempo.Please necesitaria que me orientara. Porque necesito viajar para fin de mes y de verdad que la necesito por cuestiones de salud . Gracias el cliente.12/16/2024.I have problems with this Power Battery, it seems to be defective, it constantly turns off every 15 or 20 minutes, so I have to disconnect the cable and reconnect it, and I am only feeding an Insulin thermos. Despite being fully charged, it turns off, I have tried all the output ports and it always does the same thing. And I bought it precisely because I need it. I am going on a trip and I need to take cold insulin with me since the trip is several hours long and I even bought another Bank-Power of this one. The second one I bought has not arrived yet, I hope it is not defective too. It also does not respond to the power button, despite pressing the power button, it does nothing, it stays off all the time.Please, I would need you to guide me. Because I need to travel at the end of the month and I really need it for health reasons. Thank you, customer.
