Booster vs Laptop charger

This booster says it will charge cell phones, etc. Says nothing about laptops. Just wondering if out boondocking a bit, will it charge a laptop as well. Not sure about phones, but laptops are 19v, and this is a 12v booster. Also not sure how that equates to the watts or whatever happens to a charging current... Thanks

    That is nothing but a self contained 12V "jump" battery pack for starting a vehicle, will not directly power a laptop.

    While you could hook a small inverter to the pack, WHY?

    You can buy no fuss "universal" laptop power supplies which are designed to take 12V car cig lighter port and output 18V-21V depending on the power tip you select for your laptop.

    Power tip will automatically set the universal power supply to your laptop voltage and max current draw.

    Some of these also have a 5V USB charging port on them.

    Here is pix of one example..



    Don't remember what the brand I bought for DD, but she has been using it for 3 yrs now and has not killed it yet (and she kills everything that has wires attached to it).
  • The outputs of this unit are 12 volt for jump starting and 5 volt for USB ports. You could attach an inverter to this to produce 120 volt ac or get a 12 volt power adapter for your computer. If your phone charges from USB this would charge your phone.
