Any recommendations for one of those portable jump start boxes that you can use when you have a dead battery on your boat? Brand/model?

I usually have this charged and ready to go just in case my battery is dead. I haven't had to use it on the boat yet, but have jumped a car with it. Worked great.

One issue with the emergency boxes is their cranking amps often being low. The trick to that is you use it to help recharge the main by leaving it attached for five minutes or so before cranking. That puts some of the energy into the main and means the portable does not have to flow quite so much.
If you can, get one that can stay plugged in with automatic control. Many are just a simple charger and can have a shorter life if they stay plugged in.

I've got a antigravity battery xp10. i got the xp10 because it will crank over a diesel truck about 20+ times before it needs to be charged. They make smaller one for less $$. Check it out.
