Our Review
The most affordable, packable way into solar power — 768Wh and a 220W panel that recharges it in a few hours of sun. Great for light camping, short outages, and CPAP backup; not for heavy appliances.
Specifications
| Capacity | 768 Wh |
|---|---|
| Continuous output | 800 W |
| Surge output | 1600 W |
| Battery chemistry | LiFePO4 |
| Included panel | 220 W |
The River 2 Pro bundle is the entry point to genuine solar independence: a 768Wh LiFePO4 station plus a 220W panel, ready to run off the sun out of the box. It's the lightest, cheapest solar generator we list, which makes it ideal for solo campers, road trips, and as a grab-and-go outage kit.
Its 800W output (1,600W surge) is the honest limit — it'll run a CPAP, laptops, lights, phones, and a small fridge, but not a microwave or full-size refrigerator. The included 220W panel tops the battery in a few hours of good sun, though as always, real-world solar runs below the rating (why here).
Pros
- Most affordable solar generator in our lineup
- Light and packable for solo trips
- 220W panel recharges 768Wh in a few hours of sun
Cons
- 800W output won't run high-wattage appliances
- 768Wh is one night for most uses, not multi-day
What it actually runs
A full 768Wh charge gives about 650Wh usable — sized for one person, one night:
| Device | Typical draw | Runtime per charge |
|---|---|---|
| CPAP (humidifier on) | 60W | ~11 hours (one night) |
| Mini-fridge | ~40W avg | ~16 hours |
| Laptop | 50W | ~13 hours |
| Phone top-ups | 15Wh each | ~43 charges |
On a sunny day the included 220W panel harvests roughly 700–900Wh — more than a full refill, so a careful user can run indefinitely off the sun.
Is the River 2 Pro enough for a weekend of camping?
For one person running a CPAP or small fridge, lights, and devices — yes, especially with the panel topping it up each day. For two people or any high-wattage cooking, step up to a 1kWh bundle.
How long does the 220W panel take to recharge it?
In good sun, roughly 4–5 hours from empty — real-world solar runs below the panel's rating, so plan for most of a sunny afternoon (why).
