With your laptop "charging brick" you have absolutely NO PROTECTION. Do buy a UPS and use it at home and in the RV. Here is a link to UPS's offered on amazon.com. You can find UPS's for about $60 on up. A UPS offers protection from low voltages, voltage surges, power outages and more.
I thought . . . :h . . . . that a UPS is simply a battery that supplies power if the main 110 volts goes out. It is to give you time to save your work so you do not lose it due to a power failure.
Depending on the design, it can smooth out the power as the AC runs a battery charger which charges the UPS battery and the UPS battery powers the computer. As long as the variation in the AC isn't big, the battery absorbs the differences.
A laptop already has this functionality built in as it has it's own internal battery.
It's big spikes that can be problematic. They can fry the charging brick or even cause the battery to be damaged. In extreme cases, electricity can do crazy things. Get a lightning strike that hits the grid nearby and all bets are off.
