Belkin Bets on Semi-Solid-State Tech for Power Bank Longevity

The lineup introduces two primary models: the UltraCharge Pro Slim Magnetic Power Bank 5K and the larger 10K variant. The 5K model, priced at $69.99, utilizes Qi2 wireless charging to deliver 15W to magnetic devices while maintaining a profile 40 percent slimmer than standard competitors. While its USB-C port can output 22.5W, performance throttles significantly when charging multiple devices simultaneously, dropping to a combined 17W output.

Beyond longevity, the semi-solid-state design addresses safety concerns common in lithium-ion cells. The chemical composition reduces overheating risks—specifically swelling and fire hazards—while ensuring stable power delivery across fluctuating temperature ranges. The 10,000mAh model, costing $20 more than the slim version, adds a display and three ports, including two USB-C and one USB-A, allowing for triple-device charging. Although these accessories carry a higher cost than units with similar specifications, Belkin is banking on the extended lifecycle to win over consumers weary of rapidly degrading batteries.
