Belkin Brings Semi-Solid-State Batteries to a $70 Power Bank
At IFA 2026, Belkin integrated semi-solid-state cells into a credit-card-sized power bank, launched trackers certified for both Apple and Google networks, and reduced the price of active noise cancellation to $39.99.
Battery Innovation
Belkin’s first two UltraCharge Pro power banks feature what they call BoostSolid Cell technology. While not fully solid-state, Belkin explains that a gel-like layer alongside the liquid electrolyte allows for slimmer packaging and improved safety. The design aims to mitigate thermal runaway, fire, and swelling risks, maintaining stable charging between 0°C to 40°C.
Safety Features
The company emphasizes that these power banks meet UL2056:2025 safety standards and TSA carry-on guidelines, crucial for air travel. Belkin claims the cells last up to three times longer than competitors, retaining up to 80% capacity after 1,000 charge cycles over five years (assuming daily use).
Product Lineup
Belkin offers two power banks with BoostSolid Cell technology:
- UltraCharge Pro Slim Magnetic: Thinnest model at 8.8mm thick, equivalent to a credit card, with 5,000mAh capacity, Qi2 wireless charging (15W), and USB-C port (22.5W). Priced at $69.99 in black and sand, launching in September.
- UltraCharge Pro Display: Larger model with a display, offering up to 60W USB-C Power Delivery for rapid charging. Costs $89.99.
Market Timing
While not the first to market with semi-solid-state batteries, Belkin’s distribution and pricing make it stand out. This technology is often first introduced in accessories before finding its way into larger applications like vehicles, highlighting the importance of early adoption in consumer goods.
