UDPOWER 210W Solar Panel

The 210W is UDPOWER’s high-wattage foldable, designed as the natural pairing for the S1200 and S2400 stations. At $299 on sale (MSRP $639 — only buy on sale), it sits in the same competitive segment as the Jackery SolarSaga 200W ($399), the Anker PS400 ($499), and the EcoFlow 220W bifacial ($429).

The case for the UDPOWER 210W is straightforward: at $100-200 less than the comparable Jackery/Anker/EcoFlow panels, with a 5-year warranty matching or exceeding the competition, and with universal connectors that work cross-brand.

The case against is that this is still a new SKU from a young brand, the long-term durability story is shorter, and the Amazon presence at review time was limited.

Real-World Output

UDPOWER rates the panel at 210W. In direct mid-day sun in late spring (about 65°F ambient, kickstand at optimal angle), I measured 165-185W of input at the charge controller of a UDPOWER S1200. That’s 78-88% of rated wattage, in line with field expectations.

In partial cloud cover the panel held 90-120W. In dense overcast, 35-55W. For comparison, the Jackery SolarSaga 200W I keep as a reference panel delivered 155-180W in the same conditions — a marginal but consistent edge to UDPOWER, likely due to the 10W wattage advantage and similar cell quality.

Pairing With the S1200 and S2400

The S1200 accepts up to 400W of solar input. A single 210W panel gets you to roughly 50% of that ceiling in optimal sun. Two 210W panels in parallel use about 90% of the input — close to the full capacity without overshooting.

For the S2400 (also 400W solar input), the math is identical. Two 210W panels give you the full input capacity. A single 210W panel still pushes useful daily recharge — about 1,100-1,300Wh over a full sun day, which is roughly 55-65% of the S2400’s 2,083Wh capacity.

Cross-Brand Compatibility

The included adapter pack covers MC4, XT60, and DC5521. I tested the panel against:

• UDPOWER C600, S1200, S2400 (native compatibility)
• EcoFlow Delta 2 Max (MC4-to-XT60 adapter included works)
• Jackery Explorer 1000 v2 (DC8020 not included; needed third-party adapter)
• Anker SOLIX C1000 (XT60 input works directly)

The Jackery requires their proprietary DC8020 plug, which UDPOWER does not ship. For Jackery owners, plan to source the adapter separately.

The Form Factor Compromise

Unfolded, the 210W panel is 70 inches long — about six feet. This is the unavoidable trade-off for higher-wattage foldables: more cells means more surface area means more length. Setup takes about a minute solo; two people make it easier.

The kickstand has three angle positions. In moderate wind the panel stays put; in gusty conditions weight or stake it. The carry handle is centered in the fold and the suitcase shape stays balanced.

At 13.2 pounds, the panel is manageable for one person to carry, but unfolded it’s bigger than a single-person setup is comfortable. For a fixed campsite or cabin, this is fine. For frequent breakdowns and moves, two of the UDPOWER 120W panels might be a better fit.

What’s Not Included

No IP68 rating — splash-resistant, not waterproof. No carrying case beyond the suitcase fold itself. No Anderson connector for high-voltage series chaining (which the S1200 supports but the S2400 caps at 50V anyway).

We could not confirm an Amazon ASIN at review time. For now, plan to buy direct from udpwr.com.

Who Should Buy It

Buy it if you own a UDPOWER S1200 or S2400 and want a single high-wattage panel that uses meaningful capacity of the 400W solar input, you want a 200W-class foldable at $100+ under the comparable Jackery/Anker/EcoFlow options, or you want a cross-brand panel with universal connectors.

Skip it if you primarily own Jackery stations (the DC8020 connector isn’t in the box), you need frequent breakdown/setup with a single person (a pair of 120W panels is more portable), or you want a verified Amazon listing (until UDPOWER confirms the 210W ASIN).

The Bottom Line

The UDPOWER 210W is the panel I’d buy as the partner to either S-series station. At $299 on sale it undercuts the established 200W foldables by $100-200, includes a 5-year warranty, and uses universal connectors. The Amazon listing gap is the only meaningful caveat.
