Battery Charger

Really about price and what you want charger to do. Personally I like a multi-use charger that has an engine start option, is automatic, has low and high charge rates and does multiple battery types. I bought a Scumacher at O'Reillys several years back for about 100 dollars that does everything I need. For the Pod you just need a charge capability, this charger will start TV if battery is dead. It's a SC1307.

"85 Amp Engine Starter-Powerful Enough For Starting SUV's And Trucks. Battery And Alternator Tester-Provides Charge Level And Helps Diagnose Electrical Problems. Digital Display, Led Indicators And Button Controls. Schu Eco Energy-Meets The Highest Industry Standards For Energy Efficiency. Charges Compatible Battery Types-Standard, AGM And Deep-Cycle Batteries. Microprocessor Controlled. Float-Mode Monitoring. Auto Voltage Detection. Reverse Hook-Up Protection."

You can get a much cheaper one that that is only a 12V charger which will work fine for the Pod use. I like options. I also am a Scumacher fan.

I've been using a Schauer 10 amp charger for over 35 years and it's still running just fine.  It spent most of its life on my various sailboats in a salt water environment, despite not being marine grade.  I still use it regularly.  I think it'll live longer than me.

The charge circuit is 3-5As. The converter does more than charge battery that is why it is rated at total amps. The add on charger will charge at a constant rate vice a phased rate.
