Overview
- The C1000 Gen 2 delivered 839 Wh at the 230 V outlet from a 1,024 Wh rating, with overall efficiency measured around 72–74% in CHIP’s lab.
- A full recharge averaged 1:01 with a recorded peak draw of 1,236 W, and the AC inverter sustained up to 2,000 W continuous output.
- Ultraspeed charging increased noise noticeably, while routine operation stayed modest, including 0.1 sone at a 100 W discharge.
- The compact C300 yielded 240 Wh via AC (266 Wh over USB‑C and 254 Wh at 12 V), reached full in about 1:09 at up to 329 W, and its AC output is limited to 300 W with very low noise.
- Both models use LiFePO4 cells (manufacturer claims: ~4,000 cycles for C1000 Gen 2 and ~3,000 for C300), include XT60 solar input with MPPT and robust app controls, and the C1000 Gen 2 omits the predecessor’s battery expansion port.
