I Found a Rare Power Bank That Doesn’t Feel Like a Brick in My Pocket

Right now, you can grab the Lisen Ultra Slim MagSafe power bank for just $20 on Amazon. We've been tracking the price, and this is the lowest we've ever seen, down from its usual $30 retail price. It's rare to see a magnetic portable charger drop this low, especially one that fits in a pocket so easily. Grab it now before the price goes back up or stock runs out.

The Lisen magnetic power bank is incredibly slim -- at just 0.3 inches thick, it's thinner than an iPhone 15. This means you get true mobile freedom without any annoying bulk, making it easy to take on the go.

You can charge your phone up to 100% in just 2 hours -- that's twice as fast as other portable chargers. For safety, it has overcharge protection and NTC temperature control. Lisen even added newer heat shields to reduce heat issues, dropping the temperature by 37 degrees Fahrenheit.

Plus, you can feel completely safe using it because it comes with a bunch of certifications, including FCC, UL, TUV, DOE, CEC, UN and RoHS. And if you're traveling, you can bring it into or take it out of both Europe and the United States without restriction.
