12v AUTO USB STAINLESS STEEL HEATED TRAVEL MUG FLASK WITH CAR & USB CHARGER

This Cup is brilliant, the drinks stay hot n would definitely recommend 1.

dose a good job mis two i good out in my truck

This flask seems alright so far, it's fairly well insulated, and the heating element does help to slow the cooling down of the liquid. Don't go expecting this to boil water though.To put what I am going to say below simply; Only use the included 'USB Charger' with the flask, and nothing else.I have one serious concern with this product though, the 'USB CHARGER' that is included is not a USB Charger, and is in fact very dangerous towards any electronics that could be connected to the output. USB uses a regulated 5 volts, the included car adaptor has no regulation to it at all, and kicks between 12 and 15 volts out, depending on your car. This will likely destroy and mobile phone, or other accessory if you use the USB Charger. This does, however, mean that the flask gets much hotter when connected to a car with the included adaptor, than when connected to a 5 volt USB source, such as a power bank.

Does not work on house usb points....I was hoping to use it to keep my coffee warm but it doesn't work....must be only for the car(not checked yet)

Coffee did not stay warm for Any length of time

Works well. Heats up quickly.

Excellent product

I like it but the charging port is rusty
