Jackery Explorer 300D, 288 Wh, 300 W DC output review
A 288 Wh LiFePO4 station rated 300 W, charged over USB-C, solar or a car socket, with three USB-C ports of which two are rated 140 W and an integrated cable that doubles as the handle.
The bottom line The one station in this group that publishes an operating temperature range, and the one whose USB-C provision genuinely replaces the inverter for laptop work. Its cycle figure is the weaker half of the sheet: 4000 counts without the percentage they are measured to.
A tall, narrow 288 Wh station sold on portability and on USB-C rather than on mains output.
What it publishes
288 Wh of LiFePO4, 300 W, and five outputs of which three are USB-C — two at 140 W and one at 65 W. The fifth bullet gives an operating range of −15 °C to 45 °C, which is the most useful line on the sheet and the rarest.
Where the specification thins
The cycle count is 4000, with no capacity percentage attached. A count without its percentage cannot be set beside one that has it, and two of the stations in this family do publish theirs.
Charging is quoted to 80 % in about 70 minutes with USB-C and solar together. The time to full is not published, and it is the part of a lithium charge that takes longest.
What the USB-C changes
Two 140 W ports mean most of what people actually charge — a laptop, a camera, a phone — never passes through the inverter. That skips the conversion loss and, on a pack this size, it is a real difference rather than a specification detail.
What is not here
No surge rating, and no usable capacity. For a unit aimed at electronics rather than appliances the first matters less than it would elsewhere; the second matters everywhere on this shelf.
Availability
German, French, Italian and Spanish Amazon stores quoted 159 € to 239 € when this page was compiled.
British Amazon store carries it too, priced in its own currency, which the euro range above deliberately omits.
American Amazon store returned nothing at all, so the buy button there runs a search instead of landing on an empty page.

What it gets right, and what it leaves out
Strengths
An operating temperature range is published, which four of the nine stations here omit entirely
Two 140 W USB-C ports mean a laptop and a second device can be charged without the inverter
The integrated cable serves as the handle, which removes one thing to lose
Compromises
The 4000-cycle figure carries no capacity percentage, so it cannot be compared with counts that do
Only a time to 80 % is published; the last stretch of a lithium charge is the slowest part and is not quoted
No surge rating at all, which matters for anything with a motor

Questions owners ask about this one
Why is a time to 80 % not the same as a charging time?
Because lithium charging tapers near the top: the current falls as the pack fills, and the last fifth takes disproportionately long. A quoted 80 % time and a quoted full time describe different parts of the same curve, and only one is published here.
What does 0 dB mean on a power station?
The listing states it in the fifth bullet without a measuring condition. Taken literally it describes a unit with no fan running; what it does under a heavy load is not stated, and this page does not extrapolate.
1024 Wh nominal · 2000 W continuous, 3000 W peak · 4000 cycles to 80 % · full in 49 min at 1600 W · 600 W solar at 60 V max · 10 ms UPS · 9 ports
A 1024 Wh station rated 2000 W continuous and 3000 W peak, charged in a stated 49 minutes at 1600 W, with a 600 W solar input capped at 60 V and a 10 ms switchover.
Best for: A household that will pair the station with panels and wants the input window published rather than guessed.
1024 Wh nominal · 1800 W · LiFePO4, 3500+ cycles · 0–80 % in 1 h at 800 W · 11 outputs · 14 kg · app control
A 1024 Wh LiFePO4 station rated 1800 W with eleven outputs, charged from 0 to 80 % in a stated hour at 800 W, and controllable from a phone application.
Best for: A household that wants three mains sockets and app monitoring rather than the lightest unit on the shelf.
1024 Wh nominal LFP · 2600 W · 0–80 % in 37 min · 10 ms UPS switchover · 26 dB stated · 2× 140 W USB-C · 5-year warranty
A 1024 Wh LFP station rated 2600 W that reaches 80 % in a stated 37 minutes, switches to battery in 10 ms, and carries two 140 W USB-C ports and a five-year warranty.
Best for: Someone already inside the DJI ecosystem, or anyone who needs the shortest recharge and a documented switchover time.
