Customers are saying

Customers find value in the BOOST↑CHARGE™ Power Bank 5K's fast charging capabilities, ease of use, and compact, lightweight design. Many appreciate its compatibility with various devices and the reasonable price, especially when purchased on sale. However, some customers wish it had a larger battery capacity and point out that a charging cable is not included. The sleek design and convenient portability are frequently highlighted as positive aspects.

    Great for single use charge for large devices

    Great for charging two small phones twice. Nevertheless if you have one of those 'plus' iPhones and large screen android phones, then this portable charger will only charge your phone up to 80%ish given there is energy loss during the charge and overall fast output that drains the power bank extremely fast. Only plus is that the power bank charges fairly quick and good for one charge for iPhones. if you looking to charge your iphone/large android multiple times and an ipad you definetly need to have one of those 20,000 mAh power bank.

    Very convenient that you don't have to have a separate micro/type-c usb cable to charge your powerbank. you can charge your apple iphones,ipads,etc and the powerbank itself with one lightning cable. I definitely wouldn't pay full price for this right now. 5k mah is not a very big battery. It's durable but i definitely don't think it would handle drops very well. The top part is glossy and very prone to scratches.

    Great portable charger. It’s light weight, small and uses the same cord as the iPhone. It charges fast and keeps its charge for days so no need to recharge every day.

    Have only had it for two days but it has worked well so far. After a full charge I tested it to charge an iPhone from 15%-100% and then an iPad from 50% to almost full. It charged both but its charge was fully depleted at that point and needed to be recharged. Doesn't come with any cables. Bought it on sale so it looks like a good value.

    Due to weather, it took longer for delivery. It's not heavy and just a little bigger than my iPhone Xs. It arrived with some charge on it but I went ahead and charged it fully. It charged my iPhone just as fast as if I used the wall charger. No where does it state in the description of the compatible phones but the box "made for" shows the iPhone Xs as the highest so I was happy to see in the Q&A a response that it is capable to charge an iPhone 12 (just in case I wanted to upgrade). NOTE... keep your lightning cord if you upgrade to a usb-c product as you'll need it to charge this unit.

    This battery pack is great to charging your phone during travel. The size is great to fit in a backpack. It recharges quickly. I got it on sale during Best Buy one day deals. Excellent product that retains the charge for days.

    The right size and very capable of meeting my charging needs on a trip. I have been searching for a unit like this one for some time and I finally found it. Also it was selling at a great price. I plan to get maximum service out of this charger. I will recommend it to my brothers because they have the same need. So thank you Best Buy this charger appeared in your online add at the perfect time.

    Nice slim profile. Recharges iPhone 8 plus nicely thru out the day. Having to plug it in is kind of a drag. It should be wireless for both charging and using to charge your device. Then I could charge it on the pad at night and just put it next to the phone as needed thru out the day. That would be worth $40! Still a good deal of the day for $10 though.
