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 keep up. A heated mattress pad uses about 432Wh a day at 8 hours of use, so with enough panels and good sun the Vtoman FlashSpeed 1500 can run it indefinitely.
Tips
- Queen-size heated pads draw about 90W and cycle once warm.
- You’ll still have about 1410W 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.
