Just a note for people wanting to buy these for use on 120Vac in the U.S.: I would advise against purchasing these if you expect to use these in the U.S. or any other place not using 220Vac to 240Vac electric power. Even though the packaging I received these (100 watt units) in erroneously stated 120Vac and 220-240Vac support, you should notice that the online page here on the Banggood website correctly states 220Vac to 240Vac ONLY. The website page is correct. These will not illuminate if connected to 120Vac as they are hard-wired for 220-240Vac.

This doesn't ship with any specifications OR instructions but seems to work very well. I used a USB power bank rated at 8000maH and from my measurements and observations you could probably run this vest for about 8-10 hours on this. The power bank is installed in the left-inside pocket that contains the USB cable connection. The two switches on the left breast area control power to the rear and front areas of the vest separately. These switches change color to show different modes of operation: No LED = power OFF Red LED = High power heating (continuous 1.8A current draw) White LED = Temperature Maintenance Mode (Pulsing 1.8A current draw). Blue LED = Low Heat mode (2-step Pulsing current draw). The circuitry automatically switches from Red to White mode once the vest comes up to temperature. The Blue mode can be manually invoked for further battery savings and longer life. Overall, I am impressed with construction and operation. Time will tell the story regarding longevity and reliability.

This is my favorite USB monitor meter and I have tried quite a few different models. The large bright color-coded LED displays show only what you really need to know... Voltage and Charging Current. These can be plugged into virtually any USB charger/power supply/computer that supports the standard USB-A port. I have purchased almost two dozen of these over the last year or so and seem to find new uses on a regular basis. This was sold under the Keweisi brand before and the product still bears this name and logo regardless of who else is selling it. The product is first rate and is a most valued tool in my arsenal of test equipment and consumer device charging units. I highly recommend these units if you need to know what is going on when charging USB-charged battery devices!
