Belkin has stepped into the Qi2.2 race with the UltraCharge Slim 10K, a magnetic 10,000mAh power bank priced at £69.99 and sold in Black, White, and Sand. The Belkin UltraCharge Slim 10K promises faster wireless charging, a thinner body, and a display that tells you how much juice is left instead of making you guess from blinking LEDs.
That combination is becoming the new baseline for premium portable chargers. Belkin is clearly aiming at the same buyers who have been pulled toward slim magnetic packs from rivals such as Ugreen and Portronics, but it is trying to win on polish rather than gimmicks. The result is a product that sounds less flashy than it is useful, which is usually a good sign.
Qi2.2 charging and dual-device support
The headline feature is 25W Qi2.2 wireless charging for compatible smartphones. Belkin says an iPhone 17 Pro can go from 0 to 50% in 39 minutes, and the charging system is designed to keep magnetic alignment and heat under control. A single USB-C port adds up to 30W output, and the power bank can charge two devices at once using both outputs.
- Wireless charging: 25W Qi2.2
- USB-C output: up to 30W
- Dual charging: one magnetic pad plus one USB-C device
- Pass-through charging: 30W
Slim body, built-in screen, and 10,000mAh capacity
For a 10,000mAh pack, the size is impressively restrained at 102mm by 71.6mm and 10.6mm thick. Belkin uses a frosted aluminum alloy shell and a soft silicone surface on the phone-facing side, which is the sort of detail that sounds boring until you avoid a scratched handset. The built-in display is the other smart touch, showing exact battery percentage instead of vague status lights.
Belkin says the battery can deliver roughly 44 hours of extra playback time for an iPhone 17 Pro. It also includes SmartProtect safety monitoring with a dual-chip design for overcurrent, overheating, and overvoltage, and it has passed 55 internal safety tests. TSA carry-on compliance makes it easier to justify tossing it into a backpack before a flight.
Belkin UltraCharge Slim 10K versus rival magnetic power banks
The timing matters because magnetic chargers are no longer a niche add-on; they are quickly turning into a standard accessory category for phone owners who want a cleaner, cable-light setup. Belkin’s entry does not try to out-muscle the biggest battery bricks. Instead, it leans on Qi2.2 support, a slimmer frame, and a more premium finish – which is probably the right play for a category that already has plenty of cheap grey rectangles.
The bigger question is whether buyers will pay a little more for a pack that feels thoughtfully made rather than merely spec-heavy. Given how quickly rivals are adding built-in cables, higher wattage, and color screens, Belkin will need more than brand recognition to keep this one from becoming just another very tidy power bank.
