| Specification | Value |
|---|---|
| Storage | |
| CapacityHow much energy the battery stores. Bigger means longer runtime or more of your own solar power used later. | 1,408 Wh |
| Battery chemistryLFP (lithium iron phosphate) cells are known for long life and stable behaviour with heat. | LiFePO4 (LFP), managed by VTOMAN's LIFEBMS with 10 protections |
| 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. | 3,000 cycles to 80% capacity; VTOMAN puts this at up to 10 years of daily use |
| ExpansionExtra battery units that add storage to the same system. | Not published by VTOMAN for this model |
| 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. | 2,400 W in total, 230 V, 50 Hz, pure sine wave, three AC sockets |
| AC output (surge)A short burst above the continuous rating, for appliances that draw more power when they start. | 3,200 W peak. VTOMAN says its V-BEYOND technology can run resistive loads above 2,400 W up to 3,200 W, such as heaters, toasters, ovens and coffee makers |
| USB-APorts for phones, tablets and small devices. | 3 ports at 5 V 2.4 A (12 W each) and 1 Quick Charge port at 5 V 3 A / 9 V 2 A / 12 V 1.5 A (18 W maximum) |
| USB-CPorts for laptops, phones and tablets. Power delivery up to 100 W can charge most laptops. | 2 ports, up to 100 W each (5, 9, 12, 15, 20 V at 3 A; 20 V at 5 A) |
| Car outletA 12 V socket like the one in a car, for car accessories. | Yes: one cigarette-lighter port, 12 V 10 A |
| DC5521A small round DC connector used by routers, cameras and LED lights. | Yes: 2 outputs, 12 V 10 A each (regulated 12 V) |
| Wireless chargingA pad on the unit that charges a compatible phone without a cable. | No: not part of the maker's specification list |
| Charging | |
| AC chargingHow fast it charges from a wall socket. Higher means a shorter wait. | 1,500 W maximum |
| Time to charge from the mainsHow long a full charge takes from a wall socket. | 0 to 100% in 1 hour with the 1,500 W charger, according to VTOMAN |
| Solar inputHow much solar panel power it accepts. A higher figure fills the battery faster on a sunny day. | Anderson input, 12-60 V, 600 W maximum, with built-in MPPT. VTOMAN recommends its VS400 400 W panel; panels with MC4 plugs need an MC4 to Anderson adapter cable |
| Solar charging timeHow long a full charge takes from solar panels, in the conditions the maker names. | 4 to 8 hours with 400 W of solar panels, according to VTOMAN |
| Car chargingCharging from a car's 12 V or 24 V socket while driving. Slow, but useful on the road. | DC input 12-20 V, 200 W maximum; VTOMAN gives 12 to 14 hours from a car outlet |
| Pass-through chargingWhether it can power devices while it is itself being charged. | Yes: VTOMAN says it can be recharged while it charges devices |
| Backup switchover (EPS)What happens when the grid fails. EPS means it takes over automatically. | 10 ms or less (UPS function) |
| Solar and off-grid | |
| Works with solar panelsWhether you can charge it from solar panels. Yes means a built-in solar input or a compatible solar setup; read the detail for the voltage and power limits. | Yes: Anderson solar input, 12-60 V, 600 W maximum, with built-in MPPT. |
| Off-grid useWhether the maker describes it running with no grid connection at all, for example in a cabin, van or off-grid home. Backup only means it covers power cuts but needs the grid the rest of the time. | Yes: VTOMAN lists outdoor, camping and RV use, charged from solar, the car or the mains. |
| Housing and warranty | |
| Dimensions (L × W × H)Check the space before you buy, including room around it for airflow and cables. | 393 × 280 × 270 mm, as listed by VTOMAN (axis order not stated) |
| WeightMatters for lifting, wall mounting and moving it. | 19 kg |
| Operating temperatureThe range it is rated to work in. Cold and heat can reduce performance. | Discharging -20 to 55 °C; charging 0 to 55 °C |
| Noise levelFan noise while working. | Not published by VTOMAN |
| Protection ratingIP ratings show protection from dust and water. IP55 and IP65 are rated for outdoor-style exposure; check the installation guidance. | Not published by VTOMAN |

The estimate assumes 85% of the rated capacity is usable after conversion losses. VTOMAN 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 VTOMAN says this product works with. Anything not listed here is not confirmed.

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 FlashSpeed 2400. Figures come from VTOMAN's UK shop page for the FlashSpeed 2400 (features, specification table and FAQ), last checked on 13 November 2026. VTOMAN's US store lists the 120 V model with the same capacity and ports. A value that VTOMAN does not publish is shown as not published.
We do not show prices, because they change often and differ between sellers.

Common questions about VTOMAN FlashSpeed 2400
What can the FlashSpeed 2400 run?
VTOMAN rates it at 2,400 W continuous. Its V-BEYOND technology can run resistive loads such as heaters and kettles up to 3,200 W, but not motor loads that start with a surge.
How fast does the FlashSpeed 2400 charge?
VTOMAN quotes 0 to 100% in 1 hour from the mains at 1,500 W, 4 to 8 hours from 400 W of solar panels and 12 to 14 hours from a car outlet.
Is the FlashSpeed 2400 the same as a home battery?
No. It is a portable power station that you plug devices into. An installed home battery is wired into your electrics by an electrician. See our guide to plug-in and installed home batteries.
