Detailed overview: Jackery SolarSaga 40 W Mini foldable solar panel
The Jackery SolarSaga 40W Mini is the brand's most compact solar panel, and it answers a question the 100 or 200 W models leave aside: how to produce solar energy when you carry all your gear on your back. At just 1.5 kg with a two-panel fold, it straps to a backpack without unbalancing your stride.
Its small surface is offset by cell quality. Jackery uses high-efficiency monocrystalline cells here, around 25%, among the best available on a portable panel. In practice that means the advertised 40 W is reached in good sunshine, and the panel stays productive even when the sun is not at its zenith.
The panel deploys in seconds thanks to its two leaves and built-in kickstands, which let you tilt it toward the sun rather than laying it flat. That is a decisive detail: at this power, orientation easily swings output by 30 to 40%. IP65 certification protects it from dust and showers, welcome at camp where you do not always fold your kit away at the first cloud.
In practice this format suits owners of a compact power station, such as an Explorer 100 Plus or Explorer 240, or anyone wanting to maintain a large portable battery over several days. It will slowly recharge a 1 kWh station, but that is not its purpose: for that, a 100 or 200 W carried by car remains far more relevant.
Compatible with Jackery stations via its DC connector, it carries a 3-year warranty. It is the logical companion for hikers, bikepackers or kayakers wanting to extend their electrical autonomy without sacrificing kilos in their pack.

☀ How fast does this panel recharge a power station?
The Jackery SolarSaga 40W Mini panel (40 W) recharges a Jackery Explorer 1000 v2 (1070 Wh) in ~38h or an EcoFlow Delta 2 Max (2048 Wh) in ~73h, in full sun.
| Compact / mid | Recharge |
|---|---|
| Jackery Explorer 100 Plus (99 Wh) | ~3h30 |
| EcoFlow River 2 (256 Wh) | ~9h10 |
| Jackery Explorer 500 v2 (512 Wh) | ~18h |
| DJI Power 1000 (1024 Wh) | ~37h |
| High capacity | Recharge |
|---|---|
| Anker Solix C2000 Gen 2 (2048 Wh) | ~73h |
| Jackery Explorer 3000 v2 (3072 Wh) | ~110h |
| Allpowers R4000 (3456 Wh) | ~123h |
| Fossibot F3600 Pro (3840 Wh) | ~137h |
Estimate in full sun (ideal conditions). In practice, count on 3 to 5 hours of truly useful sunlight per day, so a full recharge may span several days depending on weather and orientation.
Comparison
Around 110 euros, the SolarSaga 40W Mini compares to the small portable solar panels sought for hiking, via searches like "portable solar panel hiking" or "lightweight solar panel bivouac". Here is how it stands against three alternatives: the Jackery SolarSaga 80W, the BigBlue 28W and the EcoFlow 45W.
| Criterion | SolarSaga 40W Mini | Jackery SolarSaga 80W | BigBlue 28W | EcoFlow 45W |
|---|---|---|---|---|
| Power | 40 W | 80 W | 28 W | 45 W |
| Weight | 1.5 kg | ≈ 4 kg | ≈ 0.7 kg | ≈ 2.3 kg |
| Efficiency | ≈ 25% | ≈ 24% | ≈ 22% | ≈ 22% |
| Kickstands | Yes, built-in | Yes | No | Yes |
| Observed price | ≈ 109 € | ≈ 249 € | ≈ 60 € | ≈ 149 € |
In short, the SolarSaga 40W Mini sits exactly where hiking needs it: twice as powerful as the BigBlue 28W while staying portable, and far lighter than the SolarSaga 80W which assumes motorised travel. Its 25% efficiency is the best of the group. The BigBlue remains unbeatable for charging a phone directly at minimum weight, and the EcoFlow 45W plays in the same league at a higher price. To feed a compact station off-grid over several days, this Mini format is the most accomplished compromise.

Our tester's review: Julien De Jurquet
We took this SolarSaga 40W Mini on a three-day trek, and it is the first Jackery panel we genuinely agreed to carry on our backs. The 1.5 kg goes unnoticed once strapped to a hiking pack, where a 100 W at 4 or 5 kg makes itself felt on the first climb. Deployment is immediate: two panels, two kickstands, and it holds the angle even on stony ground. In full mountain sun, it kept an Explorer 240 station afloat throughout the trip, partially recharging it each afternoon during breaks. You have to be realistic about what 40 W represents: this is not a panel that fills a large station in a day, but a charge maintainer and a top-up for small devices. Seen that way, it does exactly its job. Build quality is Jackery's usual standard, with a solid fabric cover and a practical handle. Two caveats: the price per watt stays high compared with bigger panels, and under cloud cover output drops fast given the small surface. For hiking and light bivouac, it is still the most sensible format.
Frequently asked questions: Jackery SolarSaga 40 W Mini foldable solar panel
It can, but very slowly. At 40 W it is designed to feed a compact station such as an Explorer 100 or 240, or to maintain the charge of a larger model. To fill a 1 kWh station in a day, aim for 200 W or more.
Yes, that is its whole point. At 1.5 kg with a two-panel fold, it straps to a backpack without hampering your stride, unlike 100 W panels that often weigh 4 to 5 kg.
Its IP65 rating protects it from dust and splashes, so a passing shower. It is not designed to stay exposed to heavy rain for long, nor to be submerged.
It connects to Jackery stations via its DC connector. It can also feed other brands of station provided you have the adapter matching their solar input.
