Belkin UltraCharge Pro 10K

A Battery Built for More Than Phones

Belkin's UltraCharge Pro 10K combines a 10,000mAh reserve with enough wired output to handle larger devices. Its USB-C port can deliver up to 60W, opening the door to laptops and gaming handhelds as well as phones. A status display shows the remaining charge and surfaces alerts without requiring guesswork.

Magnetic Charging at the Full Qi2 Rate

The pack attaches magnetically to compatible phones and supplies up to 15W through Qi2. That makes it useful as a cable-free top-up while still leaving the faster USB-C connection available when speed matters more. The larger body is the tradeoff for twice the capacity of Belkin's new Slim 5K model.

Gel Layers Made for a Longer Life

Inside, Belkin's BoostSolid design uses gel layers that are meant to slow battery degradation. The company says the pack retains 80 percent of its original capacity after 1,000 charging cycles, which works out to about five years if it is fully cycled every other day. Belkin estimates that lifespan at up to three times longer than a typical magnetic power bank.

A Practical Step Up From a Pocket Pack

The UltraCharge Pro 10K is aimed at people who want one portable battery to cover a phone and more demanding gear. Its mix of magnetic convenience, 60W wired charging, and an on-device display gives the extra size a clear purpose. It will be available through Belkin and retailers including Amazon starting this month.
