HOTA S6 Ultra Dual Channel Smart Charger (GaN+SiC, 480W AC / 650W DC, 1–6S)

The HOTA S6 Ultra is the next-generation upgrade to the proven S6 platform, now featuring GaN (Gallium Nitride) + SiC (Silicon Carbide) power supply technology for improved efficiency, reduced heat, and better real-world performance.

Maintaining a compact dual-channel design, the S6 Ultra delivers strong output on both AC and DC, with improved thermal handling and higher balance current for faster, more stable charging.

This is the ideal charger for users who want serious performance in a dual-port setup without stepping up to larger multi-channel units.
