Q: How long does it take for the battery to be fully charged?
A: If your charger is 2A, it takes 8 hours to fully charge.
If your charger is 1A, it takes 16 hours to fully charge.
To shorten the charging time, please try to use a charger with more than 1A.
Q: Why does the power bank output have a round 7.4V DC connector instead of a 5V USB port?
1. The 7.4 V battery provides a higher voltage than the 5 V battery, so that the heating vest can be heated faster than the 5 V USB heating vest.
2. Our heated areas are very large, so some power banks with 5 V cannot operate our heating vest.
3. Although the cost of a 7.4 V power bank is higher, we still insist on using it to provide consumers with a better product experience.
Q: What is the correct procedure for washing a vest?
A: Take out the battery pack and wash the vest by hand or machine (put it in a laundry bag).
Q: Can I use other power banks to charge the vest?
A: For safety reasons, please use the included power bank. Other power banks may cause vest malfunction due to lack of safety protection.
