Specifications
Last checked on 11 November 2026. The grey text under each name explains what the value means.
| Specification | Value |
|---|---|
| Storage | |
| CapacityHow much energy the battery stores. Bigger means longer runtime or more of your own solar power used later. | 288 Wh rated capacity |
| Battery chemistryLFP (lithium iron phosphate) cells are known for long life and stable behaviour with heat. | LFP (LiFePO4) |
| Cycle lifeHow many full charge and discharge cycles the cells are rated for before they hold less than the stated share of their original capacity. | Not stated. EcoFlow describes '5 years of outdoor power freedom' in its text, without a cycle count |
| ExpansionExtra battery units that add storage to the same system. | Not stated |
| Output | |
| AC output (continuous)The power it can deliver all the time. Add up the watts of what you want to run at once and stay below this. | None. The TRAIL series is pure DC |
| Peak outputA short burst above the continuous rating, for example to start a motor. It cannot be held. | 300 W maximum discharging power |
| USB-APorts for phones, tablets and small devices. | 2 ports, 12 W each |
| USB-CPorts for laptops, phones and tablets. Power delivery up to 100 W can charge most laptops. | 2 ports, 140 W each (input and output) |
| Car outletA 12 V socket like the one in a car, for car accessories. | 1 outlet, 120 W maximum |
| Wireless chargingA pad on the unit that charges a compatible phone without a cable. | Not listed |
| Charging | |
| Solar inputHow much solar panel power it accepts. A higher figure fills the battery faster on a sunny day. | 110 W maximum through the solar/car port |
| Time to charge from the mainsHow long a full charge takes from a wall socket. | Not stated for the 300 DC. EcoFlow says the series recharges in about 1 hour through a 140 W USB-C port |
| Car chargingCharging from a car's 12 V or 24 V socket while driving. Slow, but useful on the road. | Through the solar/car port, 110 W maximum |
| Pass-through chargingWhether it can power devices while it is itself being charged. | Not stated |
| Housing and warranty | |
| Dimensions (H × W × D)Check the wall or floor space before you buy, including room for airflow and cables. | 167 × 115 × 166 mm |
| WeightMatters for lifting, wall mounting and moving it. | 2.58 kg |
| Operating temperatureThe range it is rated to work in. Cold and heat can reduce performance. | Not stated |
| Protection ratingIP ratings show protection from dust and water. IP55 and IP65 are rated for outdoor-style exposure; check the installation guidance. | IP30 |
| ConnectivityHow you monitor and control it, usually through an app. | No Wi-Fi, Bluetooth or app on the 300 DC (the Plus 300 DC has them) |
| WarrantyThe period the maker covers. Read the terms: conditions and capacity guarantees differ. | 3 years in the specification table. The page text also mentions 5 years of power freedom without saying what that covers |
How long will it run your devices?

The estimate assumes 85% of the rated capacity is usable after conversion losses. EcoFlow does not state this figure, so we use a cautious assumption. Real running times vary with temperature, battery age and how each device draws power.
Compatible with
What EcoFlow says this product works with. Anything not listed here is not confirmed.
- Mains devices
- Not compatible: Not compatible: the TRAIL 300 DC has no AC output, so a kettle, laptop charger brick or TV needs a different power station.
- Solar panels
- Up to 110 W through the solar/car port.
Rules where you live
A portable power station is not wired into your home, so it is simple to use almost anywhere. Connecting one to your home circuits to power the house is different, and the rules for that vary by country. See our country guides for the rules, incentives and prices where you live.

Where this information comes from
We have not tested the TRAIL 300 DC. Every figure comes from EcoFlow's TRAIL Series DC Portable Power Station page (the comparison table of the TRAIL 200 DC, 300 DC and Plus 300 DC), last checked on 11 November 2026. A value that EcoFlow does not state is shown as not stated.
We do not show prices, because they change often and differ between sellers.

Common questions about EcoFlow TRAIL 300 DC
Can the TRAIL 300 DC run a kettle or a laptop?
Not directly. It has no AC socket, only DC ports. A laptop that charges over USB-C at up to 140 W works; a device with a mains plug does not.
How long will 288 Wh last?
Divide 288 Wh by the device's draw for a rough running time. Our calculator above assumes a conservative 85% usable energy.
Is it a home battery?
No. It is a small portable power station for outdoor and travel use. An installed home battery is wired into your electrics by an electrician. See our guide to plug-in and installed home batteries.
