How many amps does a portable generator pump?
Other portable generators offer a greater low-voltage output, perhaps pumping out 8 or 10 amps. Here’s where a bit of caution needs to be exercised. Check your generator manual to determine if this is a regulated, tapered output, or simply an unregulated “constant amperage” output. This is important. When batteries are low, a big fat bulk charge is not a problem, but when batteries get close to their capacity, they can be overcharged.
How to tell if a battery is fully charged?
To avoid being fooled by the surface charge that’s present on a freshly charged battery, you’ll need to stick a good, heavy load on it for a minute or two, shut off the load, and then test the voltage. A fully charged, 12-volt “flooded acid” battery reads 12.6 volts. If you’re close to that, it shouldn’t be a problem to stop charging. Batteries are very receptive to charging when they are deeply discharged, but the closer they get to “full,” the harder it is to pump current into them. Some RVers figure once they’ve hit the 12.5-and something mark, they’re good enough to go.
What do RV batteries do?
Batteries are the heart of your RV electrical system. They keep the lights on, the control boards in many appliances operating, and turn the pump over so you can take a shower. We may not think much about them, particularly when hooked up to shore power, with a converter keeping up with the low-voltage needs. But step away from shore utilities and head out for a session of boondocking, and you’ll soon know if your batteries are staying happy.
Can a portable generator produce clean electricity?
Many portable generators, particularly the “contractor” style, do not produce “clean” electricity. A few spikes here and there, a lot of electrical “noise,” can raise Cain with sensitive converter-chargers. If using a portable generator, the purest (and safest) electricity available will come from a pure sine-wave system. Check out Honda or Yamaha portable inverter generators as an example of something that won’t eat your electronics. If your rig has a built-in “genset” like an Onan or similar, your electricity should be clean and fully edible for a fancy (expensive) converter-charger.
Can a portable generator be hooked up to a battery?
Many portable generators have a “12-volt” output, and yes, this can be hooked up to the house battery system. The issue is the output. If the generator offers a low-ball output (we’ve seen some that offer a 3-amp output), you’ll be running through a lot of generator fuel to catch up on your power needs.

How to charge battery bank while camping?
A handy way to charge a battery bank when you are free camping is to use a 230V generator. We recommend to the quiet camping models like the Honda EU series (not the industrial building site type ones). The Honda EU models produce a very clean output signal which is suitable very sensitive electronics. Better still, it;'s very quiet. There is a social convention though - don't run a generator outside the hours of 8am-8pm, and if you have close neighbours, ask if they mind first.)
How many amps does a 12V battery have?
The 12V output is usually limited to around 8 amps, the voltage can fluctuate and is not suited to effectively charge batteries. You can use the 12V output to partially charge your battery in emergency situations (say your car battery is flat) but keep an eye on your battery for overcharging & excessive gassing.
