EverFrost can be charged 4 different ways: 95W adapter, car charging cable, 100W solar panel, or 60W USB-C port.

For a detached battery, use the solar or USB-C inputs.

For the powered cooler by itself, use the adapter or car charging cable.

EverFrost is not entirely waterproof because the USB port of the battery is exposed. If you can prevent it from being exposed to water, you can take it on a boat or place it near the shore.

• Store EverFrost 12 to 24 hours before its first use.
• Avoid leaving EverFrost in the sun for a long time. Store it in a dry place with shade.
• Fully charge EverFrost before storage and every 3 months during.
• Dump internal water before storage.

They signify 3 protection levels: Low, Medium, High. If you connect EverFrost to a car charging cable, set the protection level to M or H. If you connect it via a battery power source, such as a portable power station, you can set the level to L.

If you lift and tilt EverFrost over 30 degrees, the compressor stops for your safety. Place the powered cooler on level ground for 5 minutes, and you can resume normal use.

Any 11-60V solar charger with an XT-60 female connector.

• Turn off all outputs when not in use to avoid energy loss.
• Store in a dry and cool area.
• Check the battery capacity each week. If the battery level is below 30%, charge the power station to 100%. Fully charge it once every 3 months.

• You can use this formula to calculate this time: (1536 × 0.8) / Device Wattage
• Note: This formula only applies to devices with 300W or greater.

When any control buttons are turned on, even if no devices are being charged, there will be a certain amount of no-load power consumption. We recommend turning off the button when you are not using the power station.

No, AC input is a priority input source if both are connected. When AC recharging is not used, it will automatically switch to DC recharging.

The output power of the solar charger is not only related to the weather but also the area of direct sunlight. For maximum sunlight and larger output power, adjust the position and angle of the solar charger.

The solar panel is not waterproof. Avoid direct exposure to water, rain, and moist environments.
