Collecting information about possible power sources

New page

Like most electrical devices ThinkPads are commonly connected to a public power grid providing 100V to 240V of alternating current (AC). This alternating current is converted to direct current (DC) by an external AC power adapter. For example, 240V AC is converted to 20V DC. This direct current is the power input for a ThinkPad to run the device, to [[Maintenance#Battery treatment|charge the battery]] or both at the same time.

But other power sources are possible. Most of them require a kind of converter to generate the required input of a ThinkPad model. Lenovo lists an [http://support.lenovo.com/en_US/detail.page?LegacyDocID=migr-68305 adapter set] for most models. With alternative power sources ThinkPads can operate long-term independet from a grid.

== cigarette lighter receptacle ==

The [https://en.wikipedia.org/wiki/Cigarette_lighter_receptacle cigarette lighter receptacle] is a defacto standard DC connector in automobiles. It provides 6V or more commonly 12V, but this can fluctuate depending on the state of the car engine. A DC-to-DC converter can compensate these fluctuations and provide the required voltage for a particular ThinkPad.

== EmPower ==

The [https://en.wikipedia.org/wiki/EmPower_%28aircraft_power_adapter%29 EmPower] adapter is used by airlines and provides 15V DC. A DC-to-DC converter is required.

== solar panel ==

Descriptions of using solar panels to power a laptop are rare. Lenovo links to a reseller in the USA that advertises complete [http://www.sunshineworks.com/solar-computer-power-supply.htm power backup sets]. Most solar panel systems don't provide exactly the voltage used by a particular ThinkPad model. Then a DC-to-DC converter is required.

20V solar panels are available which could be used directly to charge actual ThinkPads. But no experience is available yet.

== other sources ==

There are a lot of power sources which have to be explored to be used with a ThinkPad. For example: wind, water, cranck-handle, bicycle, ...

== list of power inputs of different models ==

Different models have different energy needs and use different connectors and different voltages. Most common inputs are 20V, 19V and 16V.
