Narrative:

Many of our flight attendants are using a static inverter powered by a rechargeable lithium ion battery on our aircraft. The device is the 'halo bolt acdc portable charger and car jumper with AC outlet and car charger.' it even comes with jumper cables to jumpstart your car! The battery is much like the battery that comes in the hover boards that were banned by the FAA.they are using the halo unit to convert the dc power from its rechargeable battery into usable AC power to power their food cookers 'hot logic.' the hot logic gets hot enough; but this halo gets really hot. To make things worse they are turning them on and putting them in a galley cabinet and covering them up with their jackets and purses on top! It is just a matter of time before we have an aircraft on fire because of one of these.
