Technical specifications for the SinKeu R200 list a 155Wh 3S Lithium-ion battery configuration, typically utilizing 18650 cells. The unit operates a Modified Sine Wave inverter, which is functionally compatible with DC electronics and basic AC power adapters but may induce audible buzzing in audio equipment. Telemetry is provided via a local LCD, as the unit lacks wireless communication protocols.
Physical characteristics include a chassis weight of under 4 lbs. The "42,000mAh" capacity rating is based on 3.7V internal cell voltage, with usable 110V AC capacity affected by approximately 15-20% inverter efficiency losses. Sustained loads exceeding 150W may trigger thermal shutdown protocols, particularly in environments with limited ventilation.
Operational Note: Pass-through charging is not recommended for this unit's battery chemistry to prevent premature degradation. Recharging through DC input (solar or wall) is rated for a 7-8 hour cycle.
The Anker 521 offers LiFePO4 chemistry and faster recharge times for high-cycle deployments. This unit is part of the portable power stations category of mobile energy devices.
