Choose Your 12V Battery Setup

Pair your 12V 1000W inverter with the right 12V LiFePO4 battery for RVs, boats, camping, small appliances, and backup power.

Power Scenario Typical Devices Power Demand Recommended Battery Setup Battery Capacity
Essential 12V Backup Basic backup use Lights / Wi-Fi / Phone Charging / Small Fan / TV Light Load For daily essentials and small devices
12V 150Ah Battery
1.92 kWh
Extended Runtime Setup RV & camping power Fridge / Freezer / TV / Laptop / Coffee Maker / Small Pump Medium Load Longer backup time with more capacity
12V 200Ah Plus Battery
2.56 kWh
Maximum Runtime Large-capacity 12V backup RV / Boat / Off-grid Cabin / Longer Backup Use / Multiple Appliances Heavy Runtime Large 12V battery capacity for longer use
12V 320Ah Bluetooth Battery
4.10 kWh

💡 Tip: This is a 12V inverter. Use a 12V battery system only. Do not connect batteries in series, as series connection increases the voltage to 24V or higher. For longer runtime, choose a larger 12V battery or connect identical 12V batteries in parallel only if supported by the battery manual.

Estimate Your 12V Backup Time

Choose a common load or enter your own power usage to estimate how long each 12V battery setup can keep your inverter running.

Choose Your Power Load

Not sure? Start with one of the common 12V inverter load presets below.

W

Estimated runtime = nominal battery energy × 94% peak inverter efficiency ÷ power load.

Essential 12V Backup

Compact backup capacity for lights, Wi-Fi, phone charging, small fans, TV, and daily essentials.

12V 150Ah Bluetooth Battery 1.92 kWh
≈18h

Extended Runtime Setup

More capacity for RVs, boats, camping, refrigerators, laptops, and longer daily use.

12V 200Ah Plus Battery 2.56 kWh
≈24h

Maximum Runtime

High-capacity 12V backup for longer RV, marine, cabin, and off-grid use.

12V 320Ah Bluetooth Battery 4.10 kWh
≈39h

Estimated runtime is for reference only and is calculated using nominal battery energy and the inverter's 94% peak efficiency. Actual runtime may vary depending on battery condition, battery settings, appliance load, operating temperature, wiring, and overall system efficiency. This is a 12V inverter. Use a 12V battery system only. Do not connect batteries in series, as series connection increases the voltage to 24V or higher.
