well if you want electricity of grid you could buy yourself a small solarinverter (compact and easy to transport or move)which uses a battery and/or a solar-panel …you can recharge your batter with a small solar-panel …and if you do not have one you can just use your battery and recharge with a charger or let your truck recharge it .I bought myself a small “Sunraiden” its great and works great what I like most about it it keeps my cell phone charged because it is pure sine. Hope my reply helped you to get power easy and with no hassle. Keep us posted!
