obody wants a swollen lithium-ion brick warping their travel bag or threatening an airport security line. At IFA 2026 in Berlin, Belkin introduced semi-solid-state cells into two of its new power banks, attempting to fix the physical vulnerabilities of standard portable power. In technical terms, this chemistry replaces part of the volatile liquid electrolyte inside standard lithium-ion packs with a dense, gel-like matrix, bridging the gap between conventional pouch cells and true solid-state hardware.
Belkin markets this setup under the BoostSolid badge, claiming it drastically curtails thermal runaway and internal swelling. That technical premise mirrors the SolidSafe approach from Better Mobile Xperience, trading slight packaging complexity for dramatically improved structural resilience under repeated charging cycles.
Belkin has moved part of its flagship charging range to semi-solid-state cells, which add a gel-like layer to the liquid electrolyte inside the battery.
If you have ever had to retire a backup battery because its casing began to bulge dangerously after a hot summer commute, this chemistry targets that exact failure mode before it starts, keeping internal temperatures lower under continuous high-wattage draw.
Laptop Power and Compact Sizes
The flagship of the new hardware lineup is the UltraCharge 22K, which pairs a 22,000mAh capacity with an integrated digital display and a built-in retractable 65W USB-C cable for $100. Belkin engineered this pack squarely for laptops and tablets, taking direct aim at the premium 65W bricks that Anker currently dominates. For lighter daily commutes where shedding pocket weight matters more than keeping a laptop running for six hours, the compact UltraCharge 11K cuts capacity in half to 11,000mAh for $60. Both units hit Belkin's online store, Amazon, and retail shelves in early September.
Alongside the semi-solid-state models, Belkin rounded out its IFA showcase with standard lithium accessories. The UltraCharge Pro Slim Magnetic Power Bank fits a 5,000mAh battery into an 8.8mm chassis no larger than a credit card, delivering 15W Qi2 wireless charging alongside wired USB output for $70. If multi-device throughput is your bottleneck, the UltraCharge Pro Power Bank 10K costs $90 for 10,000mAh, dual 60W USB-C ports, a USB-A port, and an integrated status screen that monitors both output wattage and real-time thermals.
Trackers, Stands, and Wall Plugs
The company also rolled out four tracking accessories under the SureFind label. The entry-level coin-shaped SureFind Spot runs $15 for keychains and bags, while the $27 SureFind Card slips into wallet slots and passport holders. The $25 SureFind Loop Cable Tag incorporates an integrated USB-C cable so you do not have to carry a loose cord, and the $40 SureFind Wallet Stand combines tracking, card storage, RFID shielding, and an adjustable kickstand. Belkin finished the lineup with a $25 magnetic ring stand and $27 compact 30W USB-C wall chargers matched to MacBook Neo colorways.
Paying $100 for a 22,000mAh battery bank is a modest premium over generic lithium bricks, but the built-in 65W cable and non-swelling chemistry justify the entry price for anyone who relies on portable laptop power. If your existing power bank is intact and runs cool under load, there is no need to discard it today. But when you need a dependable travel brick that survives hot bags and heavy laptop charging cycles without ballooning, the UltraCharge 22K is one of the safest bets hitting retail this fall.
