Customer Reviews
Overall rating: 4.9 / 5 from 48 reviews.
Very well built charging unit with very fast mag charging system. No problems with this one works great.
Love this charger our iPhones including iPad all up seven times on its full charge and still had charge left over, a little heavy for my small bag, but in the backpack, I think I might get a smaller one just for me.
I really love this one. I can charge my phone almost 4 times on a full charge. It has all the ports you need but it’s a bit bulky which I don’t mind.
This power bank is a lifesaver on the road! No more waiting to charge my devices one by one. It's a must-have for any traveler. 5 stars!
I'm impressed! This power bank is the perfect travel companion. It charges all my devices simultaneously, and its fast charging capability is incredible. Love it!
Searched for a while and found this item. Once received it was much better than I assumed. Very happy with my purchase. Would buy again.
Other than a long delivery time, the experience was very good. My charger arrived in good condtion. It was fully charged on arrival, so I was able to test it right away. The charger works great with plenty of battery power to keep my devices charged. Glad I bought it!
Great charger
Just got it. Seems to work as expected.
Looks solid; works well
Purchased in 2024 for a trip. Worked great in Europe and love the fact I don't need to carry cables, just the adaptor for the country I was in. 1 year later, the screen is starting to short out, and it gets extremely hot when charging. I am hesitant to plug in to charge and walk away. I just decided to buy another one though, as this is the best portable charger with magsafe I have found.
👍
Works great strong battery supply!
I haven’t use it yet.
Great powerbank! I have an iPhone 14 Pro Max and I’m able to get almost 4 full charges with this powerbank!
Great vacation charging station
This charger is fabulous, all that we need for our O/S trip in March. We have tried it out with all our phones etc & it is very fast and so easy to use.
Well made power pack.
Best all around portable chargers. Sleek design, lots of options. I would definitely recommend this product.
Really love this. It's pricey but delivers what I want Yet to test it on my S9 tablet as it's going to be my main travel power bank.
Finally found a wireless battery bank worth buying and keeping. This one actually charges my phone much faster than my phone discharges while in use. And it is capable of almost 3 full charges on a single charge of the battery bank. No product on Amazon can do anything like this one can. I have had to return 2 battery banks because their capacity was much lower than the manufacturer claimed, couldn't charge my phone faster than it could discharge, or the battery bank itself took too long (one of them, 3 days) to charge. This battery bank has none of those issues whatsoever, and the customer service was amazingly quick and helpful when I had an issue with the transaction. I would recommend this to anyone.
