BMX SolidSafe Brings Semi-Solid-State Batteries to Consumer Power Banks at $59.99

What it is

The BMX SolidSafe Power Banks are among the first consumer power banks to ship semi-solid-state battery cells. The lineup includes three SKUs: the SolidSafe 5K (5,000mAh, $59.99), the SolidSafe Air 5K (same capacity but 6.8mm thick in a titanium enclosure, $59.99), and the SolidSafe 10K (10,000mAh, dual USB-C 30W, Qi2 15W wireless, full-color LCD, $79.99). BMX debuted the series at CES 2026 and is selling direct through heybmx.com with Amazon rollout in Q2 2026.

What's interesting

The "semi-solid-state" clarification matters. Android Central confirmed these are not 100% solid-state batteries; roughly 90% of each cell uses solid ceramic/polymer electrolyte with a 10% liquid layer remaining. True solid-state consumer cells are still 2-3 years away. The semi-solid-state design is meaningfully safer than traditional lithium-ion: less flammable, more stable under physical stress, and more resistant to puncture failures.

SolidSafe Air 5K is the thinnest Qi2 power bank on the market at 6.8mm. 9to5Mac's hands-on called out that the titanium enclosure and Qi2 15W charging in this form factor made it their new favorite MagSafe battery. For iPhone users, the magnetic attachment and 15W wireless speed exceed Apple's own MagSafe Battery Pack at similar price.

Macworld charging tests rated the SolidSafe Air 5K at 89% efficiency, the top-rated semi-solid-state power bank they tested.

The 10K model bundles dual 30W USB-C PD ports with 15W Qi2 wireless charging, a full-color LCD with per-port wattage display, and simultaneous charging of up to three devices. Tom's Guide framed the 10K as a credible laptop-capable power bank at under $80.

What's missing or unverified

BMX is a new brand spinning out of the Hyper team (a veteran charger accessory maker). The brand pedigree is solid but BMX itself has a short public track record. Babeltech Reviews noted this, for buyers concerned about post-sale support, Anker or Baseus have broader service networks.

Semi-solid-state batteries at this scale are early-generation. Long-term cycle life vs. traditional Li-ion is not yet independently validated over multi-year use. BMX claims improved cycle life; real-world degradation data will emerge over 2026-2027.

Price is roughly 30-50% above comparable traditional-chemistry power banks. For buyers who do not specifically need the safety or thinness advantages, Anker's 5K and 10K Qi2 options at $45 and $60 deliver similar charging speeds at lower price.

The Amazon rollout gap matters for warranty and return convenience. Direct-from-BMX purchases during Q1 2026 ship from heybmx.com with 30-day returns; Amazon buyers in Q2 get the standard Amazon return flow.

Who it's for

iPhone users who want the thinnest possible Qi2 MagSafe battery (Air 5K). Multi-device users who want a high-capacity power bank with dual-port USB-C 30W and wireless (10K). Safety-conscious buyers traveling with lithium-ion products who want reduced fire risk in luggage.

Not for: budget buyers satisfied with traditional chemistry at 30-50% lower price, or long-haul travelers needing 20,000+ mAh capacity (BMX tops at 10K in current lineup).

Design and practical use

The titanium enclosure on the Air 5K matters beyond aesthetics. Titanium resists corrosion from sweat and humidity far better than aluminum, which means the power bank ages well under heavy pocket use. The Qi2 magnetic alignment is strong enough to hold an iPhone through moderate hand motion during video calls or podcast playback, but not strong enough to survive aggressive shaking or a drop.

The full-color LCD on the 10K is a genuine quality-of-life upgrade. Rather than LED indicators that approximate battery level, the LCD shows exact percentage remaining, active port wattages, and estimated recharge time to empty. For travelers tracking battery status across a long day, this is meaningfully better than the typical three-LED indicator.

Verdict

BMX SolidSafe is a legitimately interesting consumer debut of semi-solid-state battery technology at accessible prices. Against the Anker MagGo Qi2 5K at $45 and the Baseus Magnetic Qi2 at $55, BMX wins on safety chemistry and build quality; it loses on brand track record and retail availability. For early adopters and safety-focused buyers, this is the right pick.
