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 32 °F to 113 °F (0 °C to 45 °C) when charging and from 5 °F to 113 °F (-15 °C to 45 °C) when discharging, and Jackery warrants the whole thing for 5 years.

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.
Our team's recommendations based on the model's capacity, output power and weight.
Comparison
Between roughly $169.25 and $406.20 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 | ≈ $207.16 | ≈ $323.61 | ≈ $403.49 | ≈ $171.96 |
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 nearly ninety pounds less. Against the Anker Solix C300X DC, its most direct rival, it offers the same capacity and the same USB-C power for nearly $196.33 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 need to understand this station's gamble before judging it, because it is unusual: Jackery removed the inverter and the 230 V sockets. The result: no more DC-to-AC conversion, so fewer efficiency losses (267 Wh delivered out of 288 Wh advertised at the charge bench, or 93 %), no more fan needed to clear the inverter's heat, and a much smaller housing. At equal capacity, 288 Wh, the 300D weighs 2.5 kg against 3.75 kg for the Explorer 300 Plus, its mains-socket sibling, and costs less. Excellent if everything you carry recharges 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 good speed with a compatible charger, but the real speed depends heavily on the charger used, a point the spec sheet does not mention. A deal-breaker if you were counting on plugging in anything with a mains plug, even a simple older-generation laptop charger. One point deserves real caution: the 2-in-1 carrying cable, presented as a handle rated to carry 10 kg (a figure never independently corroborated), deformed after a few uses for one user, causing the unit to fall and an injury, with no compensation from Jackery despite the evidence supplied. The brand's customer service, moreover, comes up regularly in complaints for its slowness. The complete absence of a fan otherwise gives a rigorously silent station, confirmed in use including under sustained load. The deliberate omissions: no Wi-Fi, no Bluetooth, no app, no UPS function, no IP rating.

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.
