Quick verdict
The Explorer 300 pairs a 292Wh LiFePO4 power station with a 40W folding solar panel in one box, weighing about 7.5 lb and rated for six devices at once through two AC outlets, a 100W USB-C PD port, two USB-A ports and a 120W car port. It suits light weekend camping and day-to-day device charging rather than running a fridge or a power tool. The one caveat is recharge speed on the bundled 40W panel, which Jackery rates at 7.5 hours to 80 percent.
Strengths
- Weighs about 7.5 lb, among the lightest in its class per the maker
- LiFePO4 chemistry rated for over 4,000 cycles and about 11 years of service life
- Six devices at once across two AC outlets, 100W USB-C PD, two USB-A and a 120W car port
- 300W continuous with a 600W peak surge covers laptops, cameras and small drones
- Ships with a 40W folding solar panel, AC adapter and car charger cable included
Weaknesses
- 292Wh is a small reserve, not enough to run a fridge or a power tool for long
- The bundled 40W panel takes about 7.5 hours to reach 80 percent charge
- The power station and solar panel may ship in separate packages, per the listing

Who this kit is for
A phone, a headlamp, a camera battery and maybe a small fan: that is the load a weekend camper actually needs covered, and it is squarely what the Jackery Explorer 300 and its bundled 40W solar panel are built for. At about 7.5 lb for the power station alone, this is a kit meant to go in a daypack or a car door pocket, not a garage shelf.
This review is based on the maker’s published specifications and on recurring owner feedback. We have not run this product ourselves.
What you get
The box holds the Explorer 300 power station, one 40W folding solar panel described in the listing as the Air model, an AC adapter, a car charger cable and a user guide. Jackery notes the power station and the panel may ship in separate packages, so do not be surprised if they arrive on different days. The station itself holds 292Wh in a LiFePO4 pack and outputs up to 300W continuous with a 600W peak surge for brief higher draws.
Capacity and output
292Wh is a day-trip number, not a backup-power number. It is enough for several phone charges, a run of a headlamp or a camera battery, and light use of a laptop, but it will not keep a fridge or a space heater going for any useful stretch. The 300W rating with a 600W peak surge is sized for laptops, drones and cameras, the devices Jackery names directly, rather than for appliances with motors or heating elements.
Solar charging
The included 40W panel is the lightweight, slow-charging end of Jackery’s solar range: about 7.5 hours to reach 80 percent in good sun, per the maker. Jackery also lists a 100W panel, sold separately, that cuts that to roughly 2.8 hours. A buyer planning to rely on solar through a multi-day trip should budget for the 100W panel instead and treat the bundled 40W unit as a trickle charger or backup rather than the main charging path.
Build and portability
At roughly 7.5 lb, Jackery describes the Explorer 300 as about 17 percent lighter than the industry average for its class, with a built-in handle meant for one-handed carrying. That weight class is where this unit earns its keep: it rides in a pack or a seat pocket without being noticed, unlike the 40-plus pound stations built for home backup. The chemistry, LiFePO4, is rated by the maker for over 4,000 charge cycles before dropping to 70 percent capacity, which Jackery translates to roughly 11 years of regular use.
Living with it
A station this size suits a charge-drain-recharge rhythm rather than sitting topped off in storage for months. Owners of small LiFePO4 power stations commonly report that keeping the unit at a partial charge, rather than always running it to empty, extends the practical life of the pack; the manual should have specific storage guidance for this model. Six ports across AC, USB-C PD, USB-A and a car socket cover most campsite charging needs at once without juggling adapters.
Alternatives to Consider
For a buyer who needs real appliance power rather than device charging, the larger Jackery Explorer 1000 v2 or Explorer 2000 v2 are a better fit, trading this unit’s light weight for a fridge-capable reserve. The Anker SOLIX C1000 sits in a similar mid-size tier with faster charging if solar speed matters more than price. For the lightest possible charging on a hike, a smaller USB-only power bank without AC output costs less and weighs even less.
Verdict
Buy the Explorer 300 and panel kit if the goal is keeping phones, lights and small electronics charged on weekend trips without adding much weight. Skip it if the plan includes a fridge, a heater or anything with a motor, where 292Wh will not stretch far enough to matter.

Jackery Explorer 300 Portable Power Station with 40W Solar Panel, 292Wh, 300W AC FAQs
Jackery does not state a fridge runtime for this model in the listing. At 292Wh, a typical compact fridge would likely run for a few hours at best; this is better suited to phones, lights and small electronics than full-size appliances.
Yes. The listing includes one 40W folding solar panel along with the power station, an AC adapter and a car charger cable.
Jackery rates the 40W panel at about 7.5 hours to reach 80 percent in good sun. A 100W panel, sold separately, cuts that to about 2.8 hours per the maker.
The maker lists six device connections at once across two AC outlets, a 100W USB-C PD port, two USB-A ports and a 120W car port.
