Display

The GRECELL HW01 has a nice compact LCD screen that's a good size for a portable power station (3.5 inches). This screen strikes a balance between being large enough to easily read key info at a glance, while not taking up too much space on the front panel.

The brightness of the LCD screen seems sufficient for most lighting conditions. Even in direct sunlight, the screen remains viewable which is important when you need to check things like remaining battery percentage outside.

The display provides the key stats you need including:

• Battery percentage
• Output wattage
• Input power
• Overload and fault warnings

It would be nice if it also showed estimated time remaining at current output wattage, but overall it's a functional display that provides the core info you need when using the GRECELL station.

Safety Features

The GRECELL HW01 has multiple built-in protections and certifications to ensure safe operation. This includes:

Overcurrent Protection

The power station will automatically shut down if detecting overloading or a short circuit in connected devices. This prevents damage from excessive power draw.

Overcharge/Overdischarge Protection

Overcharge and overdischarge protection prevents the battery from being charged or discharged outside of safe voltage levels. This extends the battery's lifespan.

Overheating Protection

If internal temperatures get too high, the cooling fans will automatically activate and the power station may shut down to prevent component damage.

FCC, CE, RoHS Certification

The GRECELL HW01 meets FCC regulations for electrical interference and is CE certified for product safety. It's also RoHS certified for restricting hazardous substances.

UL94 V-0 Fire-Resistant Shell

The device's shell is made of a UL94 V-0 fire-resistant composite material for improved safety. It's more resistant to catching fire if high temperatures occur.

Battery Management System

The integrated battery management system monitors battery health, charging status, power draw and other metrics. This helps optimize performance and safety.
