    Fast charging works great and it is a reliable brand at an excellent price. I got it on sale for $32.49 on Black Friday and previously have seen it on sale in the $40s. At full price, it is probably not worth it.

    Bought this for pending elk hunting trip, for use in charging my I phone and GPS at base camp in CO. I’ve tested it and can recharge my I phone and Garmin hand help GPS/radio about 5-6 times each. Perfect for five day hunt in CO !

    I haven’t used it much because I am not able to use it for the reason I bought which was to power my work laptop for a road trip. In stead of returning it I will keep it to keep phones and kids handheld game systems charged for any future road trips. It’s a little heavy but not a problem.

    This battery is great. I took a trip to Europe and was able to charge my I phone several times before I had to recharge the battery which recharged fairly quickly with the adapter for European plugs. It’s quite handy to have while on trips.

    2023 February Austin Texas freeze made me go buy this. It is better than others- but doesn't charge as many devices as it claims with the device being fully charged itself. It worked-but not as well as I hoped.

    Works great for keeping my phone charged during live video feed. Used for my sons bowling matches and had no problem with it. It was nice to have a backup because my phone drains battery during streaming pretty quickly.

    It's first 3 or 4 uses seemed to be good, but since then it seems the capacity has degraded. It now lasts just a bit longer than my 10k MaH device, and much less than my other 20k MaH device.

    Holds a charge well and can get up to 4 or 5 full charges for my phone before needing to recharge it. Only reason I'm giving 4 stars instead of 5 is because it's bigger and bulkier than other ones I've had.
