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.

You buy a power station, run everything for a weekend, and then realize it's empty with no outlet for 200 miles. A $60 panel that folds into your pack turns that one-and-done battery into a system you can refill every sunny day — as long as you pick a panel that actually shows you when it's catching the sun.
🏆 How It Compares
The BigBlue 28W is the budget solar-panel pick for the power-station class covered in this guide: at $59.97 it costs a fraction of the EGO stations but adds the missing solar-input half of an off-grid setup. It can't charge a 3000W station (that needs a 100W+ MC4 panel), but it pairs perfectly with the Jackery 300 and EcoFlow River 2's USB-C charging for topping up phones and small electronics.
Pros & Cons
✅ Pros
- 25.4% high-efficiency cells and a built-in digital ammeter for real-time sun-angle feedback
- Dual USB-C + USB-A outputs (up to 4.8A) charge phones, tablets, and power banks directly
- Folds to 11 x 6 x 1.4 inches at 1.5 lbs — fits in a daypack side pocket
- IP44 splash-resistant with carabiners for hanging from a tent or tree
❌ Cons
- 28W output is slow for laptops or large stations — it tops up small devices best
- No built-in battery: needs direct sunlight to charge, so output stops at dusk
- Requires angled, unobstructed sun to hit rated output
