Medical equipment: these are estimates. Test your own setup and keep a backup plan.
The numbers
| Battery capacity | 1548Wh (LFP) |
|---|---|
| Usable energy | 1316Wh (85% via AC outlets) |
| Continuous AC output | 1500W |
| Surge rating | 3000W |
| Home oxygen concentrator running watts | 300W |
| Startup watts | 600W |
| Average draw | 300W |
| Estimated runtime | 4.4 hours |
| Energy per day of typical use | 7.2 kWh |
1548Wh × 0.85 = 1316Wh usable ÷ 300W average = 4.4 hours

Recharging with solar
The Vtoman FlashSpeed 1500 accepts up to 400W of solar input. In real conditions that harvests about 1.5 kWh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.
Solar can’t fully keep up. A home oxygen concentrator uses about 7.2 kWh a day at 24 hours of use, more than the Vtoman FlashSpeed 1500’s best-case solar harvest. Solar will stretch the runtime but not sustain it.
Tips
- A 5 L/min stationary concentrator draws around 300W continuously. Always keep backup oxygen cylinders; a power station is not a substitute.
- You’ll still have about 1200W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The Vtoman FlashSpeed 1500 uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.

FAQ
Will the Vtoman FlashSpeed 1500 run a home oxygen concentrator overnight?
No. At about 300W average it runs out after 4.4 hours. For a full night you need at least 2900Wh of capacity.
How long does the Vtoman FlashSpeed 1500 take to recharge with solar?
With its maximum 400W of solar input it refills in about 5.2 hours of strong sun. With a single 200W panel, expect about 2.1 sunny days (10 hours of full sun).
Is the Vtoman FlashSpeed 1500 safe for medical equipment?
These are estimates, not medical advice. Check your device’s actual power draw, test your setup before you rely on it, and always keep a backup plan approved by your doctor or equipment supplier.
