Your phone died. Again. In these scenarios, who among us has not dreamed the dream of a future where our devices charge instantly and last forever. As capacitors—or even more exciting ...

The charging circuit here uses an ATtiny13A and a MP18021 half-bridge gate driver to charge the capacitor, and also is programmed in a way that allows for three steps for charging the capacitor.

Could you replace your phone battery with a capacitor and charge it up in record fast time? Wired Science blogger Rhett Allain investigates.

Corresponding charge time (3.6-volt input) is 2.5, 3.7, 5.5, and 4 seconds (first three versions specified for a 100 microfarad photoflash capacitor, the last for a 50 microfarad capacitor). The ...

Traditionally, capacitors are like really bad rechargeable batteries. Supercapacitors changed that, making it practical to use a fast-charging capacitor in place of rechargeable batteries. However,… ...

Don't tell Palm or WildCharge, but analysts Strategy Analytics reckon that right now wireless charging is "pointless". In fact, according to the company's latest report,… ...

The pulse width of both OC1A and OC1B must be largerthan the maximum capacitor’s charging time, which youobtain when you measure the water’s dielectric capacitor,according to the following equation : ...

These features may lead you to wonder why everything isn't running on capacitors. The primary limit to the amount of electrical charge that can be stored in a capacitor is the amount of insulation ...
