Samlex 10W Battery Maintainer Portable SunCharger

The SC-10 is the bigger of Samlex’s two SunChargers: 10 watts, twice the 5W model. Like the small one, it keeps a 12V battery topped up from sunlight while a vehicle sits, with no wall power anywhere nearby.

Samlex lists RVs, boats, ATVs, cars and trucks as its uses. For a single motorcycle, the 5W SunCharger is the one Samlex lists for bikes; this 10W panel suits the bigger stuff in the driveway.

• 10W semi-flexible panel, rugged and weatherproof.
• Direct charging, no charge controller needed.
• Prevents current flowing back from the battery to the panel.
• 10′ attached cable, plus 1′ cables with a 12V plug and with ring terminals.
• 12 x 15 x 0.53 in, 2.2 lb.
• 2-year warranty (US/Canada).

Where to put it: somewhere with direct sun, close enough for the 10′ cable to reach the battery. Use the ring terminals for a long-term hookup or the 12V plug if the vehicle has a powered outlet.

Common Questions

Should I get the 5W or 10W Samlex SunCharger?
The 10W is the bigger panel at 12 x 15 inches and 2.2 lbs, against 8 x 11 inches for the 5W. Samlex lists the 10W for RVs, boats, ATVs, cars and trucks.

Is the Samlex SunCharger weatherproof?
Yes. Samlex calls it a rugged, weather-proof design with a semi-flexible panel. It comes with a 2-year warranty in the US and Canada.

How does a solar battery maintainer connect to a battery?
Through a 12V power plug or ring terminals bolted to the battery. The SC-10 has a 10-foot cable attached, so the panel can sit in the sun while the vehicle stays parked.
