20W Solar Battery Charger Kit with Dual USB and DC
Product Overview
The 20W solar battery charger kit provides an 18V panel output and a separate 5V dual-USB connection. The 420 × 280mm monocrystalline module comes with battery clips, a vehicle plug and mounting accessories. Select a compatible charge-control circuit for battery use and match any USB load to the stated output.
Compatibility & Notes
Use a compatible charge controller for battery chemistry and voltage, and verify polarity before connecting clips. Vehicle plug operation depends on the vehicle socket wiring. The USB current specification is not a per-port or simultaneous maximum-output guarantee. Place the panel in unobstructed sunlight and keep electrical connections dry; no battery or charge controller is included.
