How customer reviews and ratings work

Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.

To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.

4.0 out of 5 starsWorks as advertised but has auto off.
Reviewed in the United States 🇺🇸 on April 24, 2023
I've read several reviews that discussed long charge times. Charge duration for the most part is a function of the amount of current your power supply can deliver. There can be limits set within the device, but If you are using a small travel charger that can only delver a few milliamps of current your charge time is going to be longer. If you use a power supply such as for your MacBook Air or larger, then charge times will be shorter. The manufacturer should discuss this more in their advertising. With that said, I received my device yesterday at 37% charge. I connected it to a larger cell phone charger (iPhone) and had a full charge in about 5 hours. The downside for me is that while it can provide power to anything that requires USB power. That device must draw enough current to disable the auto-off circuitry. I have a USB powered Bluetooth receiver I use for an older car and the receiver powered up initially but the supply turned off within 30 seconds because the current draw was so low. If you need such a supply that does not have an auto-off check out Voltaic System v25 or one of their higher capacity models.

3.0 out of 5 starsLong charging time both ways
Reviewed in the United States 🇺🇸 on May 1, 2023
PROS: It's rather large, and heavier than i was expecting. It looks and feels like it is well made and durable. Love the light up display and the ability to charge with micro OR type C to USB cords. That being said...

CONS: This thing takes FOREVER to charge to capacity. Honestly, I believe that it has only charged to display 100% a couple of times after being plugged in overnight. Sometimes only charges to 40-50% in that time or the time I have to recharge it, and I've noticed charging speed varies widely. It can be finicky about cords and charging blocks or car adapters, but once I get that magic combo correct, it performs fairly well.
I have plugged my nearly dead phone into it many many times when the LCD is showing 15% or less and it has exceeded my expectations by fully or nearly charging my phone to 100% before it runs out. In fact, in my experience it charges faster when its under 25% than it does when its over that for some reason. Another CON for some might actually be the size and weight of the unit. When it's in my purse, I definitely know it's in my purse because it is noticeably heavier than usual.
It is also about the same size as my Samsung phone, but much thicker, obviously.

My conclusion....since it has charged my phone enough for me to use it without interruption during my day I think I'm ok with keeping it and avoiding the hassle of returning/selecting a new one...I just wish it recharged itself a bit faster and was more consistent in it's charging of my phone.

2.0 out of 5 stars Very slow to charge and to discharge.
Reviewed in the United States 🇺🇸 on May 12, 2023
Color: BlackVerified Purchase
I do like the amount of power it holds but thats about it. When plugged into the wall be prepared to be waiting until the next day, as it charges incredibly slowly. The io is relatively straight forward, two type c input, four USB output. Would definitely like to see a type c output. Furthermore this device doesn't support fast charging which I verified with several different cables. When plugged into my Galaxy 22 Ultra it would sustain a trickle of charging when not in use however if I needed to make even a phone call the charger would fall short of even sustaining the same power it had at the beginning of the call. This power bank would be okay if you wanted to top off your phone while you weren't using it, but thats about it.

Compared to the one I had last, not sold here anymore, this one is not good. Overnight I can’t get it to 100% change. Maybe 85%. Quickly de-charges, Won’t buy another. I tried other USB’s and other charging blocks. No help.

2.0 out of 5 stars Quit working after using it 6 times
Reviewed in the United States 🇺🇸 on May 6, 2023

Bought it for a trip. For the first six days, it worked great. Charged it last night, all was well. Plugged my phone into it today, nothing, dead. I thought that something happened and it drained itself. Plugged it in for an hour, and nothing.

2.0 out of 5 stars Must be defective
Reviewed in the United States 🇺🇸 on March 26, 2023
Color: BlackVerified Purchase
Not only does it NOT charge my devices, but I swear it drains them as well. That really sucks cause it's a really nice sized bank and it has multiple ports for multiple devices but mine just doesn't work. Instead, I'm forced to use the one I've had for over 5 years now which still seems to get me juiced up fully in under a hour.

2.0 out of 5 stars Very heavy. Not allowed by commercial airlines, and return is not free. I was very disappointed.

I did not even open the item. It is very heavy and kind of big. Definitely not comfortable to carry in a small bag. May not be allowed by commercial airlines. Returning is not free as stated unless you have a way to print all the papers required for this return. I was disappointed that there were no other options for an easy return.

2.0 out of 5 stars Highly recommend - not anymore
Reviewed in the United States 🇺🇸 on December 12, 2022
Color: BlackVerified Purchase
Works super well! I can go camping or traveling with this portable and it can charge my GoPro, phone, selfie stick, speaker, and more without any issues. It can hold so many charges so I don’t have to worry. It has 4 USB ports so you can charge everything at once if you want. It has a clear battery display. I highly recommend this

Originally, I gave this product 5 stars because it worked perfectly. I don’t use it everyday. I only use it maybe once a month. Now, it recently stopped working at an 88% full charge. So I can charge my phone like 50% of the way and the portable charger doesn’t work anymore. I’m not sure why this is happening. It didn’t get wet or anything. It just doesn’t work pass 88% now so I had to do a review edit.

My own fault for not investigating if this battery could be taken to charge my devices on a trip. The delivery box says it right on the outside- not to be taken on airplane or cruise. Don’t really know when or how I can ever use this recently purchase. Bummer!

2.0 out of 5 stars Big, durable, long lasting slow charger
Reviewed in the United States 🇺🇸 on April 3, 2023
Color: BlackVerified Purchase
It fits fine in back packs or pockets but it's heavy. Charges very VERY slow via USB. Gotta keep my phone attached for hours to keep the charge up on road trips. Ok value if you don't need a fast charge. It will charge multiple devices at once.
