According to the release of the market supervision bureau, the rechargeable hand warmer is a new type of electronic product that uses batteries to provide energy for sustainable external heat transfer. The heating temperature is in the range of 45 ° C ~ 65 ° C, and the continuous heating time is generally more than 4 hours. It is popular with consumers because of its portability.
However, at present, the quality of warm hand products sold in the market is uneven, so consumers should choose carefully and pay attention to the safety of products. We have provided you with a few purchase tips. Let's take a look
1. Check whether the operation manual, certificate, warranty card and accessories of the product are complete.
2. Check the trademark and nameplate, and select the products marked with regular manufacturers and registered trademarks. The products without information shall not be purchased, and the identification of the input and output ports (charging and discharging interfaces) of the products shall be clear and accurate, the identification of the rated input and output voltage and current value shall be complete, and the identification of the rated capacity value shall be clear.
3. The battery capacity of the product is not equal to its effective output capacity, that is, the capacity information such as 10000mah separately marked on the conspicuous part of the product should not be viewed, but the rated capacity value in the specification parameters should be viewed, which is the actual output capacity.
4. When purchasing, we should not blindly pursue low price and good-looking, but should measure our own needs and product brand, reputation and other information.
5. Check the production date of the product, and try to select the rechargeable hand warming products produced within one year. If the production date is too long, the battery capacity will be reduced and the service life of the product will be affected.
6. Try to avoid dropping the product during use. Once the temperature is found to be significantly higher than the use temperature (45 ℃ ~ 65 ℃), stop using it immediately and place it in an open space away from people.
