 +===== use a DC adapter =====
 +Using a DC adapter for your laptop rather than an [[electrical:inverter|inverter]] + the original 110v charger can save 10% or more power that would otherwise be lost in the inversion process.

 +Many modern laptops run off 19v;  a DC adapter will convert your nominal 12v DC power to 19v.  You can buy an OEM adapter by searching ebay for something like [[https://www.ebay.com/sch/items/?_nkw=dell+(12v,auto,car,dc)+charger&_sacat=&_ex_kw=&_mPrRngCbx=1&_udlo=&_udhi=&_sop=12&_fpos=&_fspt=1&_sadis=&LH_CAds=&rmvSB=true|dell (12v,auto,car,dc) charger]], or buy one of the generic ones that meets the plug and voltage specs.  They cost about $25 in most cases.
