    I use this to charge/power my iPad Pro and iPhone pro traveling for 8 hours through flights and airports. Never need to find or fight for airport power again. Get the bigger one if you need to charge or power a laptop.

    Overall, I like the size and weight of the portable charger. Like some others, the wireless portion doesn't always work for me. I was able to charge my iPhone 16 Plus and had about 75%-80% charge left on the battery. However, when I tried to charge my phone again, I kept receiving some sort of error code after 5 minutes. Eventually, my device started charging the external battery. I'm sure there's a setting on my device that I need to adjust, but I'm looking for something very convenient and reliable that won't require me to check it every 5-10 minutes to ensure it's working.

    No, I would not recommend this to a friend

    Solves The Problem Of not Always Finding An Outlet

    For everyone who has ever had the problem of finding an outlet to plug a charger into this is the solution. It is also the solution if the power is ever out for a long period of time. This charger solved my problem of finding a outlet when traveling. Took it on a train trip to Riverside CA on Wednesday and used it to keep my iPhone charged. Was able to use the iPhone to take many pictures and videos without having to worry about keeping the iPhone charged.

    I've had one for several months now and so far it worked well. I mostly use it to charge my watch (using slow charge mode) it only takes about an hour and half and lasts for more than 5 charges before it goes low enough to need charging itself. Glad I got it.
