Overview
- Belkin introduced the UltraCharge Pro line at IFA and on Thursday, September 3, 2026 made the two models available this month through Belkin.com and major retailers.
- The smaller UltraCharge Pro Slim Magnetic 5K is a 5,000mAh Qi2 magnetic bank that offers up to 15W wireless and 22.5W wired output while the UltraCharge Pro 10K packs 10,000mAh, a smart display and up to 60W wired charging.
- Belkin says the new BoostSolid cells use a gel‑like layer alongside liquid electrolyte to raise energy density and improve thermal behavior, and it advertises 80% capacity after 1,000 cycles as a proxy for roughly three times the usable life of typical power banks.
- The company highlights safety and durability testing, including nail‑puncture, high‑temperature, drop and vibration tests, TSA carry‑on compliance, active heat dissipation and real‑time thermal monitoring on the 10K model.
- Industry coverage notes Belkin’s move follows smaller brands using similar semi‑solid approaches and that mainstream adoption could change power‑bank size and longevity, though independent long‑term validation of Belkin’s longevity and safety claims is not yet available.
