Why do shoppers love it?

This power bank comes in black or white, though you’ll get the best deal on the black one. Pick it up for just $20, or white for $24. The built-in USB-C cable can double as a carrying loop, and makes it convenient to charge your phone without having to carry an extra cord with you. You can charge as many as three devices at one time, so you won’t have to pick and choose whether to charge your phone, headphones, tablet, watch, or other device first. In addition to the built-in USB-C cable, it has a USB port and a second USB-C port to plug in more cables. It also has a digital display to quickly check the battery life of the power bank. 

Shoppers love how quickly this power bank can charge up their devices. The manufacturer says the high-speed charging can charge a Galaxy S24 Ultra to 50% battery life in less than 20 minutes. And shoppers agree that it’s fast – one reviewer said, “I love this power bank! I can charge my Samsung S25 Ultra so much faster than other power banks I tried. And super convenient to just pull this out and use it, rather than looking for a power outlet and digging out my wall charger with its cord wrapping around everything in my bag. This power bank charges itself up much quicker than the other ones I have previously used.” They also said this is perfect for their frequent power outages, so they can keep their Kindle charged to read while the power is out.

Other shoppers love that this is perfect for on-the-go use. One said, “When I’m on the road, I need a charger that can recharge my phone as well as any other digital equipment that I carry. This one checked the boxes one after the other. Transfers power quickly, efficiently, and safely. Holds its charge for a long time, not losing it over a few months.” It holds enough power for multiple charges for your devices, with the manufacturer stating it can charge an iPhone 15 up to 3.9 times, a Samsung Galaxy S24 Ultra about 2.9 times, and an iPad Air approximately 1.9 times before you need to plug in the power bank itself.
