Our Verdict
This is a liquid immersion heater, not a space heater. It heats water or coffee in a cup.
It runs at 220V. Most US homes use 110V outlets. You need a voltage converter to use it safely.
At $9.99 the price is hard to beat. But it serves a completely different purpose than a space heater.
It has none of the safety features common to space heaters. No tip-over shutoff, no overheat protection, no thermostat.
Buy this to heat a beverage while traveling abroad. Do not buy this to warm a room.
What We Like
- Costs only $9.99, making it one of the lowest-priced heating tools available.
- Stainless steel body resists rust and handles repeated exposure to hot water.
- Compact 5.71-inch size fits easily into a travel bag or backpack.
- 600W draws far less power than a standard 1500W space heater.
- Heats water, coffee, or tea quickly directly inside a cup or small kettle.
What Could Be Better
- Runs on 220V only. Standard US outlets supply 110V, so it will not work without a separate voltage converter.
- No tip-over protection. It has no automatic shutoff if the device is knocked over.
- No overheat protection. It lacks a thermal cutoff to stop it from overheating.
- No thermostat or temperature control. You cannot set or limit the target temperature.
- Cannot heat air. This device warms liquids only and provides zero room or spot heating.
