- X-Boost runs high-wattage heaters and kettles at reduced power, not at their full rating
Choose the DELTA 3 Plus if
- You plan to add an extra battery later.
- You recharge from solar or charge laptops at more than 100 W.
Choose the DELTA 3 Classic if
- You want 1 kWh for outages with no plans to expand.
