Customer Ratings & Reviews

I travel all over the world and I need to stay charged to reach friends, family and to conduct work projects. This charger, that I’m using as we speak, keeps me from having to worry about that happening as I don’t always have an adapter to use in foreign countries. You could argue it’s a little bulky but it isn’t for sitting on a desk or sliding in a carry-on bag. To be fair, if you’re like me and have cargo pockets in all your pants, it fits great on the go as well. Lastly, it’s a good value and that’s something I appreciate as I don’t like to carelessly throw my money away.

Bought this to carry in my purse. You have to get a good cube for faster charging, otherwise it takes forever to fully charge (I used my laptop charger). Recently traveled to Mexico (with stops) and really took advantage of it. Kept all my electronics charged at the beach and still had battery life left after the weekend.

Best charger by far hands down! Spent 5 days in the mountains with no electricity. Powered our devices with power to spare. It still still had more power to charge after coming down out of the mountains. I highly recommend this product.

Able to charge my phone and tablet two times And still had power left in the power back

This charger truly helped me on so many occasions such as bus and plane trips.

Light to carry around. Cord should be a little longer.

Charges in less than minutes great portable power you can take anywhere

Great portable charger !! It charge quickly & it can do multiple devices at once.

We take it fishing and everywhere we might need to recharge our devices. Really reliable charging device. Thanks again Best Buy for a Great product.

It helped me survive a concert! We had left for the concert at noon and didn’t return back to the hotel until 12 hours later!

The best external battery, has one usb port and 2 type C.

This is still my favorite portable battery charger. It is super durable and it is water proof. It holds a great charge and it does not take long to charge or charge my devices.

Great charger. Charges my devices and my phone, super fast and its very very strong resistance to dust and heat The only con is that its bulky and long so it’s much more difficult to carry in pockets and sticks out as a result.

It chargers fast, has a lot of capacity and is durable. This is the second unit I’ve purchased. I had the first one for several years and needed a second one recently. Highly recommend. It’s just works

I genuinely love this thing. It has come in clutch so many times. It is on the heavier side but it can go for months without needing to charge and it still charges my whole family's phones in one go.

Love it has come so in handy. I am able to charge my android phone several times before running out of charge. Case is durable and rugged. Charges complete in less then 2hrs.

Bought this to utilize on a training mission where the ability to plug in my cell phone to an outlet would be very limited. This power bank surprised me on how long it was able to hold a charge through extreme weather conditions, amd with how many times i could charge my phone before neesing to recharge this power bank itself. Definitely worth the money, built with rubber seal caps to cover the charging ports did a great job at keepingbthe elements out. Would buy again.

This is one tough PowerBank. Recently used on an expedition sea kayak trip in a salt water, sandy environment. Kept my Marine VHF, GPS and other electronics charged for many days. It is heavy for its size but is about as simple to operate as possible. Despite being waterproof, it was kept in a protective case. I expect many years of service from this device. It is a bit expensive but I think it was worth the cost.

This thing was somehow very hard for me to get, it was on sale, but for some reason a couple times I added it to my cart and it just disappeared when it came time for payment. I'm guessing it was some inventory control error with a third party seller that showed it available on the Best Buy website, but they weren't able to fulfill it at the point of sale. Either way, I eventually got it, and it works fine, like a battery pack should. If doesn't charge at super-high speeds, and I assume it doesn't actually perform to its 20Ah rating, but that's not uncommon with battery packs, and this one seems to underperform it's rating at about the same pace as other 20Ah batteries from other major manufacturers, so that's fine. I got it for the water resistance, and the seals and gaskets on it seem pretty solid. I haven't had any problems yet, I've had it in a fairly small bag in the rain a couple times, and had no problems, so that's great. I'm not going to try to get it wet just to test it, but I have taken it into most situations that I would risk standard battery packs, and it hasn't failed me yet. The MSRP is too high, though.

This is the best purchase ever! Bought it for a trip to Puerto Rico lasted me all day, all I needed to do was charge it over night and by the time I woke up in the morning it was fully charged. When I go to rivers in the summer I bring a portable mini fan and I can use it all day and charge my phone and it won’t affect the battery life at all. Performance is 10/10
