Jackery's SolarSaga 40 Air: A Lighter, Thinner Solar Panel for Backpackers

Jackery has officially announced the SolarSaga 40 Air for the European market, positioning it as the successor to the SolarSaga 40 Mini. The new panel brings several key improvements while maintaining the same 40-watt power output, making it particularly appealing for outdoor enthusiasts and digital nomads who need reliable portable charging on the go.

The most noticeable change is the panel's form factor. Jackery has reduced the folded thickness from 3 cm to just 2 cm, a significant improvement for anyone trying to pack this into a backpack. The company has also modified the aspect ratio of the panels, resulting in a taller but narrower profile when folded - approximately 34 cm high compared to 30 cm previously, but only about 23 cm wide instead of 25 cm. This change should address one of the main criticisms of the predecessor, which struggled to fit comfortably in standard laptop backpacks.

A new protective sleeve is included with the SolarSaga 40 Air, though this does add some bulk during use. The trade-off appears worthwhile given the other improvements. Most impressively, Jackery has managed to reduce the weight by 25%, bringing it down from 1.2 kg to just 900 grams. For backpackers counting every gram, this weight reduction is substantial.

One of the more interesting technical additions is the sun-angle indicator, designed to help users position the panel optimally for maximum solar capture. This feature could be particularly useful for those less familiar with solar charging best practices.

The SolarSaga 40 Air also introduces bifacial technology, allowing it to capture light from both sides. Jackery claims a BNPI (bifacial performance value) of 47 watts, though the practical implications of this figure for typical users remain to be seen in real-world testing.

On the connectivity front, the panel features both USB-A and USB-C ports. The USB-C port supports "USB Type-C Current" standard, which doesn't require special negotiation with connected devices - a user-friendly feature that simplifies charging. However, it's worth noting that USB Power Delivery (PD) is absent, limiting the USB-C output to 15 watts at 5 volts. This means the panel cannot deliver the higher power levels that some laptops require through USB-C. That said, many well-designed devices can accept Type-C Current, and the predecessor was similarly limited to 15 watts via USB-C.

For users with Jackery power stations, the package includes a DC8020-to-DC7909 adapter and a DC8020 cable with a USB-A/C box, allowing direct connection without USB conversion.

In terms of availability, Jackery is taking an interesting approach in Europe. The SolarSaga 40 Air will initially launch only as a bundle with the Explorer 300D power station, priced at 359 euros. A standalone version is planned for a later date. In the US, the panel is already available on Amazon for $129 (excluding tax), which suggests the standalone European pricing will likely align with the predecessor's 129-euro price point.

For comparison, the SolarSaga 40 Mini currently retails for 129 euros and was similarly limited to 15 watts via USB-C. The new model's improvements in weight, thickness, and form factor represent meaningful upgrades for the same price point, though the lack of USB Power Delivery support may disappoint users with laptops that require higher charging power through USB-C.

The SolarSaga 40 Air appears to be a solid evolution of Jackery's compact solar panel lineup, with improvements that directly address user feedback about portability and backpack compatibility. While it won't replace higher-powered solar solutions for demanding applications, it should serve well for keeping phones, tablets, and smaller devices charged during outdoor adventures.
