Portable Power Inverter

A: The WZRELB ETP is a portable pure sine wave inverter that converts DC power from selected removable tool batteries into AC and USB output. It is designed for suitable electronics and small loads during mobile work, camping, RV travel and temporary power interruptions.

A: This category covers the ETP500W and ETP600W. Both use compatible removable batteries and provide pure sine wave AC output, USB-A and USB-C PD outputs, an LCD display and an LED work light. Rated continuous output is up to 500W or 600W respectively with two or more suitable batteries, subject to battery condition, discharge capability and connected load.

A: The confirmed compatibility list is DeWalt 20V MAX battery models DCB200, DCB201, DCB203, DCB204, DCB205 and DCB206. Confirm the exact battery model before ordering. Compatibility with other packs is not established by the brand name or voltage label alone; contact us to check any model outside this list.

A: The ETP has four battery slots and supports one, two, three or four compatible battery packs. Select the battery setup according to the intended load and runtime requirements.

A: Yes. One compatible battery supports up to 250W, subject to battery condition, discharge capability and connected load. Check the battery charge level and the running and startup demand of the intended devices before use.

A: Two or more suitable compatible batteries can support up to 500W continuous output on ETP500W or up to 600W on ETP600W. Available output still depends on charge level, battery condition, discharge capability, operating conditions and connected load; battery count alone does not guarantee full rated output.

A: No. Batteries and a charger are not included. Product photos may show batteries to illustrate the installed configuration; confirm the agreed package contents in the quotation.

A: No. The ETP converts battery power into AC and USB output. It does not recharge the tool batteries. Use a suitable separate battery charger for the compatible packs.

A: No. It uses compatible removable tool battery packs supplied separately. The inverter power rating describes output capacity; it is not a measure of stored battery energy.

A: The confirmed configuration has two 120V AC US-style outlets, two USB-A ports rated 5V / 2.5A and two USB-C PD ports rated 30W per port. Match each device to the correct port and rating.

A: Yes. ETP500W and ETP600W provide pure sine wave AC output for compatible equipment. Always check the device voltage, frequency, running watts and startup requirements against the inverter and battery limits.

A: Yes. The AC output frequency is user-selectable between 50Hz and 60Hz. Match the setting to the connected equipment. This confirmed version remains 120V AC with US-style outlets; changing frequency does not change the socket or output voltage standard.

A: Suitable applications include compatible phones, tablets, laptops, camera chargers, routers, lights, fans and other small devices within the available power limits. Check the total running load and any startup demand rather than relying on the device category alone.

A: Suitability depends on the actual appliance. Motors and compressors can require substantially higher power at startup than during normal running. Provide the running watts and startup requirements so the intended load can be reviewed against the inverter limits and available battery output.

A: Multiple outputs are provided for compatible devices. Check the combined connected load, each port rating and available battery output before simultaneous use. Individual port ratings should not be added together as a guaranteed total output.

A: Runtime depends on usable battery energy and the total power drawn from the batteries. Estimate hours as usable battery Wh divided by measured total battery-side watts, including inverter and auxiliary consumption. Use the stated battery Wh or nominal voltage and Ah for energy calculations. Confirm runtime with the intended battery setup and load; no fixed runtime hours are promised.

A: The LCD shows battery channels, input voltage, AC output voltage, output power, frequency and protection alerts. An integrated LED work light provides illumination for portable use.

A: The ETP includes low-voltage, over-voltage, overload, over-current, short-circuit and over-temperature protection, together with a temperature-controlled cooling fan. Operate within the product limits and keep ventilation clear.

A: This version is designed for the confirmed compatible removable tool batteries. It should not be treated as a conventional 12V vehicle-battery or cigarette-lighter inverter, a solar charge controller or a tool-battery charger.

A: Check the LCD protection alert, battery charge level and condition, battery count, connected load and ventilation. Reduce or disconnect the load if a protection alert occurs, and follow the product manual. Contact Reliable Electric with the battery models, load details and displayed error information if the issue continues.

A: Please provide the ETP model, quantity, destination market, exact battery models and capacities, and intended device running and startup requirements. Advise any branding, packaging, manual-language or market-documentation requests for review. Package contents, available documentation and commercial terms will be confirmed in the quotation.
