Hand warmer explosion incidents like this

Not an isolated case

In February 2018, Mr. Chen from Shenzhen, Guangdong, was sleeping at home when the hand warmer he was charging suddenly exploded. Brown liquid spilled everywhere, causing extensive burns on Mr. Chen's face.

On November 3, 2016, when Xiao Wu, a girl from Jilin, was at work, the power bank she placed on her lap for warmth suddenly exploded, and the splashing liquid scalded Xiao Wu's legs.

Did you immediately want to throw away the hand warmer in your hand after seeing this? !

In fact, not all hand warmers will explode. The key is to choose the right ones and use them correctly.

There are three main types of hand warmers on the market: electrode hand warmers, heating wire hand warmers, and heating tube hand warmers.

▲Simulate heating of three types of hand warmers

Electrode-type hand warmers pose a great safety hazard and their sale has been expressly banned.

Therefore, when purchasing, you should avoid electrode-type hand warmers and choose electric heating wire and heating tube-type hand warmers.

How to use it correctly

1. Use according to the instructions

To ensure safety, you must read the product instructions carefully before first use and use it correctly as required.

2. Control the power-on time

The heating time should be controlled within 5 minutes. Remember, never charge overnight!

3. Cannot be wrapped when heated

When the power is on for heating, the hand warmer should be exposed and not wrapped in a quilt.

4. If any abnormality is found, cut off the power immediately

When the hand warmer is powered on and the temperature is found to be significantly too high, or the bag is noticeably expanded, you should immediately turn off the power and stay away from it.
