What it is, and what it is for
ROCKSOLAR RSSP30 30 W Foldable Solar Panel
A 30 W folding solar charger that packs to the size of a folded laptop and weighs under 3 lb, for keeping phones, a tablet, a GPS, headlamps and a power bank charged on a hike, a paddle trip or a week at a campsite, and for topping up a small ROCKSOLAR power station between drives.
The panel charges straight from its own ports: a USB-C PD port and a QC 3.0 USB-A port for phones, tablets and laptops, a second USB-A port, and an 18 V DC barrel output for a ROCKSOLAR power station or, through the supplied MC4 adapter, a 12 V battery via a charge controller. Monocrystalline cells on a PET laminate give 20 percent or better conversion; on a heavily overcast day expect 20 to 30 percent of the rating, enough to keep a phone alive. The fabric case is splash-proof to IPX4, with four carabiners to hang it from a pack, a tent or a rail.
Point it at the sun and re-aim it every hour or two; a 30 W panel in good sun puts about 100 to 150 Wh into a station over a day. For a station over 200 Wh, or to charge faster, step up to the 60 W panel. Unfolded 885 × 355 × 35 mm (35 × 14 × 1.4 in); folded 355 × 250 × 45 mm (14 × 10 × 1.8 in); 1.33 kg (2.9 lb). In the box: the panel, a 10 in connector cable, a 78 in DC 5.5 × 2.1 mm cable, MC4 adapter, four carabiners and the manual. 1-year warranty.

Before you order.
If yours isn't here, ask an engineer. It costs nothing and it's the step most people skip.
What if I'm not sure this is the right product?
Ask before you order. Send us what you need to run, or your pool or well figures, and an engineer will confirm the choice — it costs nothing. Or use the finder below, which sizes from what you actually run and shows its reasoning.
