Our take on the FlashSpeed 2400
- Who it suits
- Consider the VTOMAN FlashSpeed 2400 if you want 1,408 Wh of LFP capacity, 2,400 W continuous AC output, a stated 10 ms UPS and 60 min full charging.
- Who should skip it
- Skip it if you need 240 V output, want an expansion battery option, or need more than 1,408 Wh of stored energy for longer outages.
- Closest alternative
- Choose the FOSSiBOT F2400 if you want more battery capacity while keeping 120 V output and UPS functionality.
Good for
- 120 V outage backup with 2,400 W continuous AC output and 3 AC outlets.
- A refrigerator averaging 60 W, with an estimated runtime of 18.8 to 21.1 hours from our calculation.
- A Wi-Fi router and cable modem, which the site calculator estimates can run for 69 h to 211 h.
- Devices that can tolerate the stated 10 ms UPS switching time.
- Fast recharging, with VTOMAN stating a 1,500 W AC charging rate and 60 min full-charge time.
Not for
- A 240 V well pump, since the FlashSpeed 2400 provides only 120 V output.
- Buyers who want to add an expansion battery. VTOMAN does not state an expansion capacity or compatible extra battery.
- Devices that cannot tolerate the stated 10 ms interruption during UPS switching.
- Buyers who need a lightweight portable station. The FlashSpeed 2400 weighs 41.9 lb.

What the FlashSpeed 2400 can run
Estimated runtime on a full charge with one appliance plugged in. We assume 80% to 90% of the rated 1,408 Wh reaches the appliance. The start-up check compares each appliance's published start-up figure (volts times starting amps, in VA) with the stated surge rating. At small loads the station's own idle draw takes a large share, so actual runtime can fall well below the range.

Medical devices. A rating check is not medical advice; here is what device makers and the FDA say.
- CPAP without humidifier (ResMed AirSense 10/11 class): FDA: ask your device maker or supplier whether the device can run on batteries or a generator, and check settings after power returns. If the device is life-sustaining, seek emergency help. ResMed battery guide: it strongly recommends a ResMed DC-to-DC converter over a DC-to-AC inverter when running from a battery.
- CPAP with heated humidifier (ResMed AirSense 11 / 10): FDA: ask your device maker or supplier whether the device can run on batteries or a generator, and check settings after power returns. ResMed battery guide: it strongly recommends a ResMed DC-to-DC converter over a DC-to-AC inverter when running from a battery.
- Travel CPAP (ResMed AirMini): FDA: confirm with the maker or supplier that battery or generator power is suitable for your device.
- Home oxygen concentrator (5 LPM): FDA: ask the maker or supplier whether it can run on batteries or a generator, and use battery-powered lights rather than gas lights or torches when oxygen is in use. Seek emergency help if the device is life-sustaining.
- Nebulizer (compressor type), Power wheelchair or scooter charger (24 V, 8 A): FDA: ask your device maker or supplier whether the device can run on batteries or a generator, and check settings after power returns. If the device is life-sustaining, seek emergency help.
Charging: wall, solar and car
- Wall charging: up to 1,500 W; fastest stated full charge 60 min.

Questions readers ask
How long can the VTOMAN FlashSpeed 2400 run a refrigerator?
Our calculation for a refrigerator averaging 60 W is 18.8 to 21.1 hours. The site calculator estimates 19 h to 21 h for a full-size ENERGY STAR refrigerator. Actual runtime depends on the appliance's power consumption.
Can the VTOMAN FlashSpeed 2400 run a CPAP overnight?
Our calculation for a CPAP with a heated humidifier is 2.5 to 2.8 nights. Each night is 8 hours at 56.1 W. Confirm with the device maker and your doctor before relying on a power station.
Can the VTOMAN FlashSpeed 2400 run a sump pump or well pump?
The site calculator estimates 1 h to 1.5 h for a 1/2 HP sump pump at 115 V, within the station's rating. A 1 HP submersible well pump requiring 240 V cannot run from its 120 V output. Check the sump pump's starting demand before relying on it.
How fast does the VTOMAN FlashSpeed 2400 recharge?
VTOMAN states a 60 min fastest full-charge time with a 1,500 W AC charging rate. It also lists up to 600 W solar input. These are manufacturer specifications, not measured charging results.
Does the VTOMAN FlashSpeed 2400 have UPS and battery expansion?
VTOMAN states a 10 ms UPS switching time. Connected equipment must tolerate that transfer interval. VTOMAN does not state a compatible expansion battery or maximum expanded capacity. If you need expansion rather than UPS functionality, compare the Jump 1800.
