TL;DR: Belkin revealed its UltraCharge Pro series using semi-solid-state battery tech for slimmer, longer-lasting portable power. The lineup includes the 8.8mm-thin UltraCharge Pro Slim Magnetic Power Bank ($69.99) and the UltraCharge Pro Power Bank with Display ($89.99).
Carrying a portable charger usually means dealing with a heavy brick in your pocket or bag. Belkin is trying to fix that with its latest drop from IFA 2026. The tech accessory related company term revealed its UltraCharge Pro series, which uses semi-solid-state battery tech for slimmer, longer-lasting portable power. The lineup includes the UltraCharge Pro Slim Magnetic Power Bank ($69.99) and the UltraCharge Pro Power Bank with Display ($89.99).
Instead of standard liquid-cell batteries, Belkin added a gel-like layer to the battery setup. That simple tweak allows the chargers to stay lightweight, last up to three times longer, and handle heat much better — so you do not have to worry about overheating or battery swelling down the road.
