Does this provide constant power? Like can I use it to run a 12 volt diesel transfer pump?

I'm not entirely sure. Haven't tested that. Assuming it would as it will provide power when it detects a proper circuit

so if you dont have the 100.00+ doller battery you wount get the jump you need

[@thehousemann]

So as with any of these items in a particular ecosystem. It benefits those that are already invested in DeWALT that have batteries from other tools to use on this. Most brands will have their own version. Or you could also purchase a generic lithion ion battery booster.
