   * Will you have 8hrs of usable solar harvest?  Do check the [[electrical:12v:electrical_notation|Vmax and Imax specs]] for the device if you intend to charge with solar;  the max input voltage is usually quite low.     * Will you have 8hrs of usable solar harvest?  Do check the [[electrical:12v:electrical_notation|Vmax and Imax specs]] for the device if you intend to charge with solar;  the max input voltage is usually quite low.

-Wall charging is typically fastest because the manufacturer gets total control over the adapter's voltage and current output.  Note that they might not include a fast charger to reduce cost or heat stress on the battery.((particularly for Li)) +

-===Charging from car outlet===  +
-Car charging is typically slow because [[electrical:12v:alternator|alternator]] voltage tends to be fairly low((particularly for charging lead)) and [[electrical:12v:ports#the_cigarette_outlet|ciggy outlet]] current limited to 10A.  Unless one is on a road trip there is probably not enough time spent driving the vehicle to charge the device fully.  +

 Another approach might be to place a [[electrical:solar:shunt_tweaking|shunt charge controller]] between the panel and DC input and limit the voltage automatically that way. This will not work if the DC port does not "show" the controller the battery voltage. Another approach might be to place a [[electrical:solar:shunt_tweaking|shunt charge controller]] between the panel and DC input and limit the voltage automatically that way.
