1. NO POWER BANK INCLUDED, CUSTOMERS NEED TO PURCHASE ONE SEPARATELY.
2. Additional Troubleshooting Tips: If, after following the manual, the vest still does not work, please try connecting the vest via USB power by a phone charger or wall adapter. Some customers are reporting defective vests. We have found that plugging the vest into a wall adapter solves the problem most of the time. This usually happens when there is a problem with the power bank.
3. DON`T use the highest temperature for more than 20 minutes.
