BigBlue 28W Solar Panel Charger with Digital Ammeter, USB-A/USB-C Outputs | 25.4% High-Efficiency, Folding Waterproof Solar Panels with Carabiners for Camping, Backpacking, Phones, Tablets, Power Bank
The BigBlue 28W solar panel charger folds down to a 11.1 x 6.3 x 1.4-inch pack (1.5 lbs) and unfolds into a four-panel 28W array with 25.4% high-efficiency cells — enough to keep phones, tablets, power banks, and small USB gadgets topped up all weekend. The built-in digital ammeter shows real-time charging current so you can angle the panel for maximum output instead of guessing. Dual USB-C ports plus one USB-A port deliver up to 4.8A total, and the IP44 splash-resistant panels with carabiners hang from a tent, tree, or pack. It has no internal battery: it charges your devices directly in the sun, which makes it the natural budget companion to a power station for off-grid trips.

By the second morning of a trip, the phone that was your camera, map, and flashlight is down to 15% — and idling the car to charge it wastes fuel and isn't always an option. The BigBlue 28W folds to daypack size, hangs from a tree or tent, and tops phones, tablets, and power banks straight from the sun all afternoon. Honest catch: 28W is device-charging territory, not power-station refill territory — for a Jackery-size station you want a 100W+ panel.
🏆 How It Compares
The budget, pack-light entry point in the solar lineup: four high-efficiency USB panels that charge small devices directly from the sun with no station required — versus 100W+ panels that exist to refill power stations.
Pros & Cons

❌ Cons
- 28W output is slow for laptops or large stations — it tops up small devices best
