    I went in to purchase a Mophie battery charger, but they were all sold out. The employee suggested that I try this one, which was within my budget. Almost everyone has Energizer batteries in several sizes. This item says High Speed, and it really is!

    I have a usb c charger for my phone... and that part of the portable charger refuses to work at all! Ive wasted money on something that does not work for my needs and im pretty upset about that. so if you have a charger like mine, maybe you should look for another instead...

    Love that it has mumtiple inputs to charge and ourputs for charging. Its heavier than i anticipated, but perfect if its in a bag or whatever. Cant speak to its longevity, but the build is solid, so thays a good sign.

    Does what I needed it for, keeping phone charged during a power outage. It is a slow charge, takes a bit of time, but works for what I wanted it for

    Not durable. This broke on my after two years. One day it just didn’t hold a charge. Also port options are out dated.

    It works but it seems like the C port does not work well. I was thinking about returning it. Other than that it charged from the other ports well.

    This is a great thing to have when you're out and about. It takes a couple hours to charge. But after it charges. Its power at your fingertips.I like to watch my tablet on my back porch.This portable charger is perfect for me.

    Very good value product. It’s slightly large/heavy but if you’re able to get past these specification (which I did) you will be pleased with your buy. Now I’m wondering on life duration.

    I did not actually use this so I can not attest to how it works. I wanted it to take on a trip but I felt it was too heavy to carry with me all day

    It's not a faster charger given that it's only 10,000mAh but it still works well and will charge your phone in a good amount of time.

    Good charger only drawback is there is no easy way to tell how much charge you have left. My old charger had a LED display that read X% left. This one has no display.

    TRASH

    This thing does not work. It took all the batter power it had, after being fully charged, to charge my S20+ from 5% to 70% - about 3 hours. Then, after being fully charged again it took 20 minutes to DIE before being dropped in the water for my friends iPhone 14 blah blah blah. STRAIGHT TRASH, my iFrogz from 2010 was better.
