Overview

The Haier Thermocool 4800ES is a medium-capacity portable petrol generator designed to supply steady power for lights, fans, TV, fridge, small freezers, laptops and other medium household or small-business loads. It offers electric start plus recoil for convenient starting and a 230V single-phase output at 50Hz.

This model is built for regular standby use: it includes features aimed at protecting appliances and improving running life — such as an automatic voltage regulator and forced-air cooling — while keeping noise and fuel use competitive for its class.

Its fuel tank and measured consumption give long run times at typical loads, making it suitable for extended outages or day-long use on site or in a small shop.

Key features

Rated power 4.1kVA (3.3kW) single-phase output, 230V, 50Hz.
Electric start with recoil backup and included 7Ah battery for starting.
Fuel efficient with specified fuel consumption and long run time per tank.
Automatic Voltage Regulator for steadier output to protect appliances.
Noise level measured at 72 dB(A) at 7 m.

Typical load estimate for 3.3 kW rated output, keeping a 20% safety margin (≈ 2,750 W usable). Motors (fridges, ACs, pumps) need extra power for a few seconds at start-up — that is already counted.
