How to choose
Noise in decibels
Noise figures separate these picks. The QQT stays under 30 dB, the BZGG runs at 40 dB and the Amazon Basics runs at 48 dB. The Gaiatop and ASNUG describe quiet operation without a decibel figure, so compare them on size and settings instead. A lower figure suits bedrooms and offices where quiet matters.
Power, settings and ECO mode
Wattage sets how much heat a heater draws. The Gaiatop, Amazon Basics and ASNUG run at 500 watts, the BZGG gives 1000 watts on high and 700 watts on ECO, and the QQT runs at 1200 watts. The BZGG and QQT give 2 settings each, and only the BZGG lists an ECO mode. Compare wattage with settings for desk use and small rooms.
Size, handles and cords
Small size and a handle decide desk placement. The Gaiatop measures 2.6 by 5 by 5 inches, the ASNUG measures 6.1 by 5.75 by 2.87 inches and the QQT measures 8.2 by 5.9 by 5.5 inches. The BZGG has a carry handle and a cord about 4 feet long, and the QQT has a hidden handle for lifting. The Amazon Basics weighs 1.4 lb for moving between rooms.
