If you are tired of replacing batteries in your portable radio or in any other battery-powered device, using an AC power adapter is a good alternative. All you need to do is to determine the voltage(V) and current (mAh) of the device. Then, attach the appropriate adapter to the place where the batteries make contact inside the device.
The converter works by the use of a low voltage wall outlet power supply. The power supply provides low voltage power through the cable. The unit comes with "dummy batteries", these batteries are put in place simply to complete the electrical circuit. Meanwhile, a powered battery is inserted into the device to provide the power source.

What is important is what comes out of that power supply, I.e., 9V. To run it off a battery, you would not use the AC adapter. You would connect your DC 9V source to a plug identical to the one coming out of the adapter and plug that into the power jack on the tablet.
Their new demonstrations show that it converts heat to electricity with over 40 percent efficiency — a performance better than that of traditional steam turbines. The heat engine is a thermophotovoltaic (TPV) cell, similar to a solar panel''s photovoltaic cells, that passively captures high-energy photons from a white-hot heat source and converts them into electricity.

Small devices can harvest the energy, which can reduce battery dependency, extend device lifetimes, and minimize the environmental impact. Instead of having to physically travel to devices in remote regions to constantly replace batteries, the device can be powered remotely by ambient energy sources such as everyday RF wireless signals.
To turn these energy sources into useful power sources, manufacturers like Linear Technology and Texas Instruments, among others, have crafted ultra-low-power boost DC/DC converters that can generate sufficient voltage and power to drive an array of wireless sensors and transmitters.
Harvesting energy from nonconventional sources in the environment has received increased attention over the past decade from researchers who study these alternative energy sources for low power applications.
Once started, the boost converter/charger can effectively extract power from low-voltage output harvesters such as TEGs or single-/dual-cell solar panels. The data sheet suggests that the boost converter can be started with input voltage V IN as low as 330 mV. Once started, it can continue to harvest energy from the DC source down to 80 mV.
The key innovation is a nanoscale spin-rectifier that can convert extremely low-power RF signals of less than -20 dBm into a usable direct current voltage. This device overcomes a primary pain point of existing RF energy harvesting rectifiers, which struggle to operate efficiently at low ambient power levels.
Researchers at Tohoku University, the National University of Singapore, and the University of Messina developed a novel technology to efficiently harvest ambient low-power radiofrequency (RF) signals into direct-current (DC) power.
