Detailed overview: Jackery 288 Wh power station without mains sockets
The Jackery Explorer 300D opens a still-rare category for the maker: the all-DC power station. Where a conventional station carries an inverter to manufacture 230 V AC, the 300D goes without and offers only USB and 12 V outputs. That choice has direct, measurable consequences for size, weight, noise and price.
The battery is a 288 Wh LiFePO4 pack rated at 4,000 charge cycles, roughly a decade of regular use. Total available power reaches 300 W, spread across three USB-C ports, a USB-A port capped at 15 W and a 120 W 12 V cigarette-lighter output. The first USB-C port goes up to 140 W and works both ways: it is how the station recharges, and it is also what feeds a demanding laptop.
Recharging illustrates the product's philosophy well. On 140 W USB-C the station goes from empty to full in 2 h 18. On solar it accepts up to 100 W through its 8020 interface (16 to 28 V, 6 A) and fills in 3 h 30 in good conditions. From a car's cigarette lighter, allow 4 h 06. The supplied cable is a find: designed to take 10 kg, it acts as the carrying handle while being the 140 W charging lead, which rules out the classic forgotten-charger problem.
The rest comes down to a few figures: 2.5 kg, an upright format of roughly 119 x 180 x 188 mm that slips into a camera bag, an LCD screen, a built-in LED lamp and above all no fan, the removed inverter no longer needing cooling. Operation is therefore rigorously silent. There is, however, no Wi-Fi, no Bluetooth, no mobile app and no UPS function. Permitted temperatures run from 0 to 45 °C when charging and from -15 to 45 °C when discharging, and Jackery warrants the whole thing for 5 years.

⚡ How long will this power station run a device?
With 288 Wh, the Jackery Explorer 300D external battery runs a fridge (50 W) for ~4h55 or an LED TV (90 W) for ~2h45.
| Home | Runtime |
|---|---|
| Mini fridge (45 W) | ~5h25 |
| Refrigerator (50 W) | ~4h55 |
| American fridge (150 W) | ~1h40 |
| Dehumidifier (300 W) | ~50 min |
| Outdoor & workshop | Runtime |
|---|---|

Rough estimate: real consumption varies, and very power-hungry appliances (heating elements) must stay below the output power.
What is this power station best for?
-
Hiking & Bivouac Ideal
This is clearly what the 300D was drawn for. At 2.5 kg for 288 Wh it holds almost three times the energy of a large power bank without weighing much more, and its 2-in-1 carrying cable takes 10 kg while doubling as the 140 W charging lead. On a wild camp it recharges a phone about ten times, runs a head torch, an e-reader and a camera, and its built-in LED lamp serves as camp lighting. With no fan, it makes no sound at all inside a tent. Its one limit on foot remains weight: for a day hike, a 20,000 mAh power bank will do.
-
Camping & Tent Ideal
On a campsite the 300D covers everything that plugs into USB or 12 V: phones, tablets, a speaker, a fan, a mattress pump, lighting. Its three USB-C ports and USB-A port serve four devices at once, and the 120 W cigarette-lighter output takes a small 12 V cool box through the day. Its LiFePO4 chemistry (4,000 cycles) withstands years of seasons, and a 100 W solar panel refills it in 3.5 hours on a sunny pitch. The thing to check before leaving: it has no 230 V socket at all, so make sure every piece of kit you take charges over USB or 12 V.
-
Photo & Video Ideal
For a photographer or videographer working outdoors, the 300D is particularly well judged: its 288 Wh recharge dozens of camera batteries, and its 140 W USB-C port tops up a laptop so you can offload cards on site. The compact vertical format slips into a camera bag, 2.5 kg costs nothing over a day of scouting, and the absence of a fan means no stray noise during a sound take. Do check your kit, though, if any of it demands mains power, a cinema battery charger for instance: the 300D delivers DC only.
-
Road trip & Car Suitable
In a car or a converted van, the 300D plays the part of a discreet backup reserve: it recharges from the cigarette lighter in 4.1 hours while you drive, then runs phones, a laptop through the 140 W USB-C port and a 12 V cool box once parked. Its 2.5 kg stow anywhere, and total silence is a real comfort when sleeping on board. It does not replace a station with 230 V sockets if you carry small appliances: for a kettle or a hob you need to move up a class.
-
Remote work Suitable
For working outside, on a terrace, in a garden or in a co-working space with no socket, the 300D covers half a day of laptop use through its 140 W USB-C port while keeping enough left for a phone and earbuds. The absolute silence, with no fan, is welcome on video calls. Two reservations for desk use: with no 230 V socket, an external monitor or a printer stay out of reach, and with no UPS function it does not protect against a brief outage. This is a mobility station, not a backup supply for a fixed workstation.

Compatible solar panels
A selection of photovoltaic panels that suit this station's solar input (up to 28V / 100W), best match first.
Comparison
Between roughly 150 and 350 euros, compact stations now split into two families: those that keep a 230 V socket and those that have dropped it. The table sets the 300D against its mains-socket sibling and its two direct all-DC rivals.
| Criterion | Jackery Explorer 300D | Jackery Explorer 300 Plus | Anker Solix C300X DC | EcoFlow Trail 200 DC |
|---|---|---|---|---|
| Capacity | 288 Wh | 288 Wh | 288 Wh | 192 Wh |
| 230 V socket | None | Yes | None | None |
| USB-C max | 140 W | 100 W | 140 W | 140 W |
| 12 V output | Yes, 120 W | Yes | Yes | No |
| Weight | 2.5 kg | 3.75 kg | 2.8 kg | 1.83 kg |
| Observed price | ≈ 179 € | ≈ 279 € | ≈ 349 € | ≈ 149 € |
In short, the 300D is the most interesting entry in the table if you can live without a mains socket: at identical capacity it weighs 1.25 kg less than the Explorer 300 Plus and costs a hundred euros less. Against the Anker Solix C300X DC, its most direct rival, it offers the same capacity and the same USB-C power for nearly 170 € less. The EcoFlow Trail 200 DC is lighter still but only holds 192 Wh and does without a 12 V output, which rules out a cool box. If on the other hand you need even one 230 V socket, the Explorer 300 Plus remains the right call despite the extra weight.

Our tester's review: Christophe Delpuech
You have to understand this station's gamble before judging it, because it is unusual: Jackery removed the inverter and the 230 V sockets. The result is no DC-to-AC conversion, so no efficiency losses, no fan to shed the inverter's heat, and a far smaller casing. At equal capacity, 288 Wh, the 300D weighs 2.5 kg against 3.75 kg for the <a href="/power-stations/jackery-explorer-300-plus/">Explorer 300 Plus</a>, its mains-socket sibling, and it costs a hundred euros less. In real life that choice is either excellent or a deal-breaker, with no middle ground. Excellent if everything you carry charges over USB-C or 12 V: phone, tablet, laptop, camera, drone, e-reader, 12 V cool box, lighting. The 140 W USB-C port charges a MacBook Pro at full speed, and the three USB-C ports serve three devices with no adapter. A deal-breaker if you were counting on plugging in anything with a mains plug, even an older-generation laptop charger. Two design details deserve a mention. The 2-in-1 carrying cable is a genuinely good idea: it is the handle, rated to carry 10 kg, and it is also the 140 W charging lead, so you cannot leave it behind. And the complete absence of a fan, a direct consequence of dropping the inverter, gives a rigorously silent station, which counts inside a tent or during a sound take. The deliberate omissions: no Wi-Fi, no Bluetooth, no app and no UPS function. At this price and for this use, those absences make sense.
Frequently asked questions: Jackery 288 Wh power station without mains sockets
No, and that is its defining choice. It offers DC outputs only: three USB-C ports, a USB-A and a 12 V cigarette-lighter socket. Removing the inverter is exactly what lets it weigh 2.5 kg and run without a fan.
Yes, through its 140 W USB-C port, which charges a MacBook Pro or a Windows ultrabook at full speed. A laptop that only charges from a conventional mains brick, however, cannot be connected, since there is no 230 V socket.
Two hours and eighteen minutes on 140 W USB-C, three and a half hours with a 100 W solar panel in good conditions, and a little over four hours from a car's cigarette lighter.
Yes, completely. By removing the inverter, Jackery removed the heat source that made a fan necessary. The station therefore has no moving parts and makes no noise at all, even charging at full power.
No. The Explorer 300D has neither Wi-Fi nor Bluetooth and connects to no app. Everything is read on the built-in LCD screen, a choice consistent with its simple, compact positioning.
