Question:

I live in a cold climate and batteries die all the time in winter. Is the 900A enough or should I go bigger?

Hey Ryan - cold weather definitely changes the equation.

While the 900A jump box # VX95NR can work in winter, cold batteries need more help, so the 1,200A # VX63NR is usually the smarter pick. More amps means less strain on the jump pack and quicker starts when temps .

Projecta units also outperform a lot of cheaper jump starters in the cold thanks to their battery chemistry and safety controls. If winter reliability matters, sizing up is rarely a regret.
Here are the temperature specs they list:
Operating temperature: -4ºF to 140ºF
Operating temperature (charging): 32ºF to 113ºF
Storage temperature: 14ºF to 140ºF

How cold does it usually get where you’re at? And what type of vehicle and battery is it? If it's a small low amp battery, the 900a may work just fine and you could save some money there.
