Energy wattmeter GreenBlue GB620E for mains 220V, max 16A, plug-in power/energy monitor

GreenBlue GB620E is a compact plug-in energy wattmeter designed for 220V mains and rated up to 16A. The device provides real-time power (watts) readouts and cumulative energy (kWh) tracking, enabling straightforward monitoring of household appliances. Its plug-and-play form factor makes it easy to move between sockets to measure consumption of devices such as TVs, kettles and chargers within the specified limits.

Advantages

The GreenBlue GB620E offers immediate digital feedback on instantaneous power and total energy used without requiring installation or configuration. Its portable, plug-in design allows quick checks of different appliances and locations. The unit helps users identify energy-intensive devices and supports simple consumption comparisons over time. The clear numeric display and single-socket interface make the device convenient for everyday use.

Suitable for

• Measuring power and energy use of household appliances (TVs, audio equipment, lamps)
• Checking consumption of kitchen appliances such as kettles and microwaves (within rated limits)
• Monitoring charging power of phones, tablets and laptop chargers
• Quick energy audits in rented accommodation, offices or workshops

Key specifications

• Supply voltage: 220 V mains
• Maximum current: 16 A
• Measured values: real-time power (W) and cumulative energy (kWh)
• Form factor: plug-in single-socket wattmeter
• Display: digital numeric readout for instantaneous and accumulated measurements

How to use

Plug the GreenBlue GB620E into a standard 220V wall socket, then plug the appliance to be measured into the wattmeter. The device will display instantaneous power in watts and will accumulate energy consumption over time in kilowatt-hours. For accurate readings ensure the connected appliance does not exceed the 16 A rating and that the socket wiring is in good condition. To compare devices, measure each appliance under typical operating conditions for a representative period.

Usage recommendations

Use the wattmeter indoors in dry environments and avoid exposing it to moisture or mechanical stress. For high-power appliances, confirm that peak and continuous currents remain within the 16 A limit. Periodically record cumulative energy readings to track consumption trends and support informed decisions about appliance usage and replacement.
