Camping Power Inverter Guide

Choose camping power around the batteries you already use, the equipment you want to run and the time between recharges. WZRELB offers portable inverters compatible with DeWalt 20V MAX batteries and inverters for a dedicated battery bank.

Choose your camping power setup

Your use	Conditions to check	Models and next step
Carry-in power for compatible lights, electronics and small AC loads	Compatible DeWalt 20V MAX batteries; one to four packs. One battery supports up to 250W. Two or more compatible batteries support up to 500W (ETP500) or 600W (ETP600) continuous, subject to battery condition, discharge capability and connected load.	ETP500 / ETP600 — two 120V AC outlets, two 5V / 2.5A USB-A ports and two 30W USB-C PD ports. Confirm the voltage and charging requirements of each device.
A campsite or camper with a dedicated battery bank	RBP3000 supplies up to 3000W continuous when supported by the selected battery system. Check running load, motor startup, battery/BMS capability and installation requirements.	RBP3000: 12V DC → 120V AC / 60Hz example Select a different DC input, AC output or frequency if your setup requires it. This example does not make a 12V accessory socket suitable for a battery-bank inverter.

Check the load before packing

Add the devices used together. Compare electrical input watts with the inverter’s continuous limit and check the rating of the outlet or USB port in use.
Review kettles, heaters and cooking equipment individually. These can be demanding loads. A pure sine wave label alone does not establish that a device will run.
Check fridge and pump startup. Running watts do not describe startup demand. Confirm the appliance requirement and the selected inverter’s surge capability before buying.
Match output voltage and frequency. ETP500/600 provide 120V AC with user-selectable 50Hz / 60Hz. For RBP3000, order the version that matches your battery and equipment.

Plan runtime and recharging

Battery capacity and load determine how long you can camp between recharges. Use the battery manufacturer’s usable-energy information, account for inverter consumption and conversion losses, and allow for battery condition and temperature. A 600W inverter rating does not mean 600Wh of stored energy or a guaranteed runtime.

ETP500/600 accept one to four compatible batteries, but one battery limits output to up to 250W. They do not charge DeWalt batteries. Bring the required compatible batteries, a separate charger and a suitable way to recharge between uses.

What to buy and prepare

ETP500 / ETP600: inverter, compatible batteries and a separate compatible battery charger. Batteries and charger are not included; the ETP inverter does not recharge the batteries. It is not a 12V car-socket inverter.
Battery-bank inverters: confirm the exact DC/AC/frequency version, a suitable battery system, battery charging equipment and installation parts. Check the selected product’s package contents; cable and protection requirements depend on the installation.

For a battery-bank installation, have the battery/BMS, DC cables, fuse or breaker, ventilation, grounding and AC connections checked for the selected model. Follow its manual and use a qualified installer for fixed wiring. Do not backfeed an AC outlet or connect inverter output directly to grid or shore power.

For a fixed installation that specifically needs 120V/240V split-phase output, review the home backup selection guide and SPT6000 configurations with your installer. SPT6000 is not a 12V-input inverter.
