AURA SLIM

5,000 mAh Semi-SSB | Qi2 25W | 8mm Ultra-Thin

India's first 8mm ultra-slim Semi-Solid-State power bank. Fits in a shirt pocket alongside a 7.5mm iPhone. Qi2 MagSafe magnetic alignment charges iPhone 0 to 50% in 30 minutes. 1,000+ cycle life means daily charging for over 2.7 years.

Semi-SSB is not experimental. CATL shipped 6 GWh of semi-solid-state cells in 2025 for automotive applications. Consumer power bank applications launched commercially at CES 2026.

Why Semi-SSB is the Future

Six reasons Li-Ion can't compete.

1,000+Cycles

1,000+ Real Cycles

Semi-SSB cells maintain above 80% capacity after 1,000 full charge cycles. At once-daily charging that is 2.7 years of reliable use vs 1.4 years for standard Li-Ion.

<5%Liquid

No Thermal Runaway

With less than 5% liquid electrolyte, there is virtually no flammable material. Semi-SSB passes TSA/IATA carry-on and UN38.3 air transport standards.

8mmUltra-Slim

8mm Ultra-Slim Design

250-300 Wh/kg vs 150-200 Wh/kg in Li-Ion means AURA SLIM can be just 8mm thick - thinner than an iPhone.

140WPD 3.1 EPR

140W Output - Safe

Improved ion transport enables high-power discharge without dangerous heat build-up that makes Li-Ion unsafe above 65W.

#1CATL & BYD

Backed by Industry Leaders

Semi-SSB is the direction of CATL (37.9% global battery share), BYD, and WeLion - same companies supplying Tesla and Apple.

2026First Mover

First Mover in India

Semi-SSB power banks launched commercially globally in January 2026. BILLIARDS is India's first brand with BIS IS 16102 registration.

The Bottom Line

Standard Li-Ion = cheap, fails fast, fire risk, 18% gross margin. Semi-SSB = 1,000+ cycles, airline safe, 8mm slim, 140W capable. Semi-SSB is not a future technology - it is commercially available right now with zero Indian brand using it.
