what would be the best deep cycle battery charger for a small pop-up camper?

We Answered:

Those little solar jobs are great for battery maintainance but look closely at the maximum charging rate if you expect it to charge the battery in a reasonably short period of time - deep cycle batteries range from 650 to 900 amp hours capacity - a 900 amp rated battery 50% discharged requires 50 amps for 10 hours, or 25 amps for 20 hours, or 5 amps for 100 hours to fully recharge it.

Most campers however come factory equipped with a power inverter which both provides 12VDC for lights and such and also will charge the battery in 24 to 36 hours when the camper is plugged into A/C power.

In the event your camper is not equipped with an inverter I would recommend a basic 30 amp "Automatic" automotive battery charger for normal charging needs and if you can afford to equip it with a solar charger also that will eliminate the need to plug the unit in and charge it regularly ( at least 3 days once every 3 months ).

I want a solar charger for my iPhone 3G. Which one works best for it?

We Answered:

It will, but its a little slow. Just make sure you get the right adapter.
