Although manned flights in a tethered helicopter go back to 1917 and in airships to the previous century, the first manned free flight by an electrically powered aeroplane was not made until 1973 and most manned electric aircraft today are still only experimental demonstrators.

Mechanisms for storing and supplying the necessary electricity vary considerably, and each has distinct advantages and disadvantages. Batteries were the earliest source of electricity, first powering airships in the nineteenth century. Modern battery types include Lithium-based and a number of other less widely used technologies. Such batteries remain a popular power source today, although they still have limited life between charges and hence limited range. Batteries are also often used for temporary storage of electricity generated by another source. However such a craft must remain tethered to a ground facility, and the higher it flies, the heavier the weight of cable it must lift with it.

The power output of solar cells is small, even when many are connected together, which limits their use and is also expensive. However their use of freely available sunlight makes them attractive for high-altitude, long-endurance applications. For endurance flights, keeping the craft in the air all night typically requires a backup storage system, which supplies power during the hours of darkness and recharges during the day. Its advantage over a small battery is the ability to charge and discharge much faster with higher peak currents. Unlike a battery, the fluids are not stored in the battery but are drawn in from outside. This offers the prospect of much greater range than batteries and experimental examples have flown, but the technology has yet to reach production. However, compared to a power cable, power beaming carries much less weight penalty as altitude increases.
