Diagram of a radioisotope heater unit. A radioisotope heater unit (RHU) is a small device that provides heat through radioactive decay. [1] They are similar to tiny radioisotope thermoelectric generators (RTG) and normally provide about one watt of heat each, derived from the decay of a few grams of plutonium-238—although other radioactive isotopes could be used.
A rechargeable electric hand warmer. This device plugs into a USB port to charge its battery. It can also be used to charge or power other devices via USB. Battery operated hand warmers use electrically resistive heating devices to convert electrical energy in the battery into heat.
Charging a 12 V lead–acid car battery A mobile phone plugged in to an AC adapter for charging. A battery charger, recharger, or simply charger, [1] [2] is a device that stores energy in an electric battery by running current through it.
Some rechargeable battery types are available in the same form factors as disposables. Rechargeable batteries have higher initial cost but can be recharged very cheaply and used many times. Common rechargeable battery chemistries include: Lead–acid battery: Lead acid batteries hold the largest market share of electric storage products. A ...

A storage heater or heat bank (Australia) is an electrical heater which stores thermal energy during the evening, or at night when electricity is available at lower cost, and releases the heat during the day as required. Accumulators, like a hot water storage tank, are another type of storage heater but specifically store hot water for later use.
