5W Solar Charger with 5000mAh 7.4V Li-Battery

The WILLFINE SP200 delivers twice the battery capacity of entry-level solar chargers. Its 5W monocrystalline panel feeds a 5000mAh / 7.4V Li-ion battery, with dual DC outputs (12V/1A and 6V/1.5A) supporting a wide range of trail cameras and accessories. Type-C 5V/2A input enables top-up charging from a power bank. Four LED indicators show charge status at a glance. IP66 rated; -20°C to 60°C operating range.

Double the Capacity, Double the Compatibility

Where the SP100 Pro is built for single-camera scenarios, the SP200 doubles down: a 5W monocrystalline panel + 5000mAh / 7.4V Li-ion battery delivers roughly twice the storage and twice the daily charging throughput. Equally important, the SP200 features dual DC outputs (12V/1A and 6V/1.5A) — meaning one charger can simultaneously power a 12V trail camera and a 6V outdoor accessory, or be redeployed across a wider range of devices over time. For farms, multi-camera deployments, or hunters who don't want to commit to a single-brand ecosystem, SP200 is the flexible mid-tier choice.
