Specifications

Operation

LCD Screen

The LCD screen displays the status of the power station.

• a: ECO Mode indicator
• b: Battery Capacity percentage
• c: Input Power in Watts
• d: Low Battery Warning icon ⚠️
• e: Temperature Warning icon ?️
• f: Output Power in Watts
• g: Overload Warning icon ⚠️
• h: Short Circuit Warning icon ⚡

Turning On/Off

To turn on: Press the AC power button / DC power button / 12V DC button to activate the respective output.

*The LCD screen stays on for 30-60 seconds. Turn on at least one of the ports (AC/DC/12V DC) if you want the display to remain on longer.

To turn off: Press and hold the power buttons to turn off the respective output.

Mode

Setting Mode: When the AC output is off, press and hold both the AC and DC power buttons simultaneously, and the frequency indicator will flash.

ECO Mode¹: In 'Setting Mode', press the DC power button to turn it on/off.

AC Frequency²: In 'Setting Mode', press the AC power button to switch.

¹ In this mode, the AC/DC output will automatically shut off after 4 hours of low load (≤10W for AC, ≤1W for DC) or no load to save power.

² AC Frequency refers to the number of AC cycles per second in an AC sine wave. The common frequency is usually 50/60 Hz.

Charging

AC Charging

Simply connect the EB55 to a standard wall outlet and start charging.

A wall AC outlet is connected via an AC adapter to the EB55's AC adapter input port.

Solar Charging

Connect solar panels (in series or parallel) to the EB55 using the solar charging cable.

Note: Please ensure your solar panels meet the following specifications: OCV: 12-28V, Input Current: 8A Max, Max Input Power: 200W max. With MC4 or Anderson connectors.

Solar panels with MC4 connectors are connected via a solar charging cable to the EB55's DC input port.

Car Charging

Connect the EB55 directly to the car's cigarette lighter port using the car charging cable.

A car's cigarette lighter port is connected via a car charging cable to the EB55's DC input port.

³ OCV: Open Circuit Voltage. The maximum voltage a solar panel can output without load.

Generator Charging

Connect the AC adapter's input plug to the generator, and connect the output plug to the EB55's DC charging port.

A generator is connected via an AC adapter to the EB55's AC adapter input port.

Dual Charging

The EB55 also supports dual charging (e.g., charging via adapter + PV, and charging via dual adapter).

Illustrates various dual charging configurations using AC outlets, AC adapters, car charging cables, solar charging cables, and DC7909-XT60 cables.

⁴ For dual adapter charging, an additional adapter (200W AC adapter + DC7909-XT60 female cable) is required.

Discharging

Estimated runtimes for various devices:

• Phone: 40-50 times (10Wh per charge)
• LED Light: 20-30 hours (at 20W)
• Television: 5-6 hours (at 75W)
• Power Tool: 5-6 hours (at 80W)
• Refrigerator: 4-5 hours (at 90W)
• Multi-cooker: 2-3 hours (at 200W)

Formula for calculating charging time: 537 Wh x DoD x η ÷ (Load Power) = Charging Time (approximate)

Note: DoD - Depth of Discharge, η - inverter efficiency. DoD = 90%, η = 90%. Load power and charging time are measured in Watts and hours.
