Customers say
Customers praise this power bank's fast charging capabilities and high-quality construction.
These work extremely well, hold a battery for a long time without use, and have charged four devices fully and still hasn’t dropped below 80% even though it hasn’t been charged in over a week. Great product and easy to use with the charging ports and cords being so easily accessible. Love it! Read more
This thing is great. Most phones need at minimum 20,000mAh to properly charge your phone to full capacity. This product meets that specification and is not unbearably heavy or too pricey. It has both types of connections (Apple, Android) and charges up well when put to charge. I am careful to put it to charge in a USB outlet that has good capacity itself. It charges by USB. I purchased the pink one because I like pink everything. I only wish it was magnetic to keep it attached stuck to my phone while charging. I appreciate that the cords have a storage position so they aren't all over or lost. It is durable as it has traveled now with me and is not easy to misplace and can be thrown around in my bags or car and still survive. Read more
This charger is great! I use it for my phone. I haven't tried it with a laptop but I'm assuming it will use more power quicker, but work just fine. I can charge my phone to 80% in about 20 minutes, sometimes less. It will stay at the charge you left it at for days. The attached cords for iPhone and usb c are awesome and lay flat within the grooves. The thing I didn't realize is that you need a stronger adapter plug. I was taking all day to charge the brick and then I realized the cube plug was getting really hot. I just bought the mint houz 67W GaN charger and it charged in less than 2 hours. I was an idiot! Now I'm really pleased with my purchase. It is heavy but I've carried it in my backpack and had no issues with charging my phone quickly when I knew I wouldn't have access to electricity. Overall, I like this because it carries a large amount of juice that I can rely on over many days. Read more
This portable power bank is very fast charging for your phone. It comes with type-C and iphone cable, and LED display showing how many battery percentage left. It is also compact and light weight easy to carry on. I use it everyday when my phone need charge. I love it and hightly recommended. ^_^ Read more
Not only is this charger a beautiful color, but it is affective and easy to use. Nice size, easily carried around in my purse. I carry it wherever I go. Very useful. Read more
Very easy to use. Long charging capability. A bit heavy, but I don’t mind. Read more
I ordered this portable charger after my old one began to short out. I was skeptical at first but I’m shocked with the durability of this charger. It has its own USB C and Apple iPhone charger connected to it so it’s easy and convenient for last minute charges. It hold its battery life pretty well also. It does take a bit to charge up compared to other portable chargers that I’ve used but it does last a long time too to it’s worth the wait. Read more
Awesome power banks that work well with the heated chairs I bought. I like that it has 2 different plug in adapters on it so you don't need an extra cord while using the power bank. All in all, it's a good, useful and handy power bank. Read more
