|---|---|---|---|
| Phone charging | 20 W | Runs it | 5.6 days |
| Laptop (while charging) | 65 W | Runs it | 41.4 h |
| Wi-Fi router and modemestimate | 28 W | Runs it | 4.0 days |
| LED bulb, 60 W equivalent (800 lumens) | 8.5 W | Runs it | 13.2 days |
| TV, 55 inch LED (LCD) | 82 W | Runs it | 32.8 h |
| CPAP machine (no humidifier) | 11 W | Runs it | 10.2 days |
| Oxygen concentrator (home, stationary) | 290 W | Runs it | 9.3 hCounts the running watts for every hour you enter.Starting watts not published; motors often need 2 to 3 times their running watts to start. |

Recharging
From the wall
Maximum AC charging input: 1,500 W.
From solar
It takes up to 2,000 W of solar. Worked at 4 peak sun hours, counting 75% of the panel rating to allow for heat, angle and controller losses:
- 200 W of panels × 4 h of sun × 0.75 = 600 Wh a day. From empty to full: 3,168 ÷ (200 × 0.75) = 21.1 hours of sun.
- 2,000 W of panels × 4 h of sun × 0.75 = 6,000 Wh a day. From empty to full: 3,168 ÷ (2,000 × 0.75) = 2.1 hours of sun.
