Belkin introduces semi-solid-state batteries in a $70 power bank.

      The automotive industry continues to assert that this battery technology is at least ten years away from practical use. However, Belkin has introduced it in a power bank priced at $69.99.

      At IFA 2026 in Berlin on Thursday, the company launched three product lines, each released separately, which include portable power sources, trackers and chargers, as well as audio devices. The standout product is the UltraCharge Pro series, which is based on what Belkin refers to as BoostSolid Cell.

      It's important to note that BoostSolid is semi-solid-state, not fully solid-state. Belkin explains that this cell features a gel-like layer in addition to the liquid electrolyte, which is different from eliminating the liquid entirely. This gel layer provides a more compact design and, according to Belkin, enhanced safety.

      The safety aspect is particularly intriguing. Belkin claims that this architecture reduces the likelihood of thermal runaway, fires, and swelling, maintaining stable charging between 0 and 40°C. It incorporates dual analogue and digital temperature sensors that monitor the cell every 250 milliseconds, cutting power if temperatures stray past set limits.

      Additionally, the design meets the UL2056:2025 safety standard and complies with TSA guidance for carry-on items. This is not merely a marketing tactic, as airlines have tightened regulations for lithium batteries in cabin luggage over the past two years. A power bank that cannot be used on flights is essentially unsellable.

      Belkin asserts that its cells can last up to three times longer than competing power banks, defining this longevity as retaining up to 80% capacity after 1,000 charge cycles. The five-year lifespan estimate assumes a full charge and discharge every two days. This means the claim reflects cycle-life metrics rather than a guarantee regarding calendar years.

      In terms of pricing, the UltraCharge Pro Slim Magnetic is particularly noteworthy. Belkin claims it is 8.8mm thick and no larger than a credit card, with a capacity of 5,000mAh. It features Qi2-certified 15W magnetic wireless charging and a 22.5W USB-C port, available for $69.99 starting in September in black and sand.

      The 10,000mAh variant, which includes a display, costs $89.99 and supports up to 60W over USB-C Power Delivery. Belkin states it can charge an iPhone 17 Pro to 50% in about 24 minutes and fully recharge itself in approximately two hours. The display indicates battery percentage, wattage, charging direction, and thermal status.

      Belkin is not the first to introduce such technology; other brands like BMX, Kuxiu, and Zens have already launched semi-solid-state power banks. What Belkin offers is improved distribution, and its pricing aligns with what consumers typically pay for quality power banks.

      The contrast with the automotive sector is notable, as LG Energy Solution indicated in August that solid-state batteries for electric vehicles are still a decade away. The challenges lie in large-format cells rather than smaller ones, making accessories the first place to see new battery technology implemented.

      In another product category, Belkin unveiled SureFind, its first line of proprietary trackers. The company has spent years providing cases and loops for third-party tracking devices and has now created its own.

      Every SureFind product is certified for both Apple’s Find My and Google’s Find Hub, allowing households with a mix of iPhones and Android devices to utilize both networks. This resolves the issue of which phone can locate lost luggage.

      SureFind Spot starts at $14.99, while the Card retails for $26.99 and features an IP68 rating, designed to fit into wallets or passport holders. The Loop Cable Tag, priced at $24.99, conceals a USB-C to USB-C charging cable within its strap. It will only be available in the Americas, Australia, New Zealand, and the Asia-Pacific region. A Wallet Stand with RFID blocking will follow in October at $39.99.

      This release also includes two standard lithium-ion power banks with retractable cables: an 11,000mAh version priced at $59.99 and a 22,000mAh model for $99.99. Additionally, a magnetic ring stand and four new color options for a 30W compact charger that matches Apple’s MacBook Neo finishes are included.

      In the audio category, three SoundForm products have been introduced. The flagship model, Isolate, is priced at $59.99 and features hybrid active noise cancellation rated up to 45dB, 32 hours of total battery life, Bluetooth Multipoint, and multiple sizes of ear tips and wing tips.

      The Dot model is available for $39.99 with active noise cancellation or $34.99 without it. The Play model is specifically designed for children aged five and older, priced at $49.99, with active noise cancellation and an optional volume limiter at 85dB. It
