Frequently Asked Questions

Q: What devices can the G300 power?

A: The G300 can power devices that consume less than 300 Watts. Please check your device's operating power before use.

Q: How long can it power my devices?

A: Working time can be estimated by: Fully charged 260Wh * 0.85 / operating power of your device. For example, a 30W device would run for approximately 7 hours (260Wh * 0.85 / 30W).

Q: Can I charge the power station while it is supplying power?

A: Yes, it supports pass-through charging. However, for safety reasons, AC outputs will not function while the unit is being charged.

Q: What kind of solar panel can I use with this power bank?

A: This unit accepts 12V-25V DC input with a 5.5x2.1mm DC connector. A 100W+ solar panel is recommended. Charging time depends on sunlight intensity and panel power.

Troubleshooting Guide

Q1: Why can't I charge my devices via the DC Output, USB Output, or AC Output?

• Ensure the Power Button has been pressed to turn on the respective outputs.
• Verify the power station has sufficient charge.
• Confirm the device's power requirement is within the 300W limit.

Q2: Why the AC adapter cannot charge the power station?

• Check if the adapter's indicator light is on.
• Inspect the adapter for any abnormal signs like excessive heat or noise.
• Try charging with alternative methods (car charger or solar panel). If other methods work, the adapter may be faulty. If none work, contact support.

Q3: Is this power station allowed on airplanes?

A: No. According to international regulations, lithium-ion batteries over 100Wh are forbidden on airplanes. The SinKeu G300, with 260Wh, is not permitted for air transport.

Q4: Why is the fan still working when the power station is off?

A: The fan operates as a built-in cooling function and may continue running even when the unit is off until the internal temperature returns to a normal level.

Operation Guide

Charging the Power Station

This power station contains an internal rechargeable lithium battery. Please charge it fully before first use.

Option 1: Charge with the AC Adapter

Connect the AC adapter to a power socket and the DC input port of the power station.

Tips:

• Full charge takes approximately 6-7 hours.
• Avoid touching the adapter during charging.
• Unplug the AC adapter once charging is complete.

Option 2: Charge with the Car Charger

Connect the car charger to your vehicle's cigarette lighter port and the DC input port of the power station. Start your vehicle's engine to begin charging.

Notes:

• Ensure your vehicle's cigarette lighter output voltage is at least 13V.
