Portable Solar Battery Charger

I'm looking for a "reasonably priced" not cheap, solar battery charger. We are going to do more dry camping this year and I want something to help keep the batteries charged. Any suggestions?

This looks like an okay unit - definitely not cheap.

You can readily make most any solar panel 'portable'. I have six 100w panels on the roof of our coach, plus two more portable that I set out as needed to mitigate shading, low winter sun, etc.

Whatever unit you choose IMHO should be at least 100 watts or higher. Smaller panels will not recharge your batteries in a reasonable time frame, and are just "toys" to occupy your time moving them constantly for the "perfect" sun exposure.

Here is a less expensive choice...

Solar Blvd. has two portable solar chargers, one 120 watt, and the other 160 watts. Both at reasonable prices.

If you want something to keep the batteries charged ALONE then you need to figure out your daily amp hour use when boondocked. A real battery monitor is a necessity for this. (Try the Victron... Victron BMV 600 Battery Monitor)

Once you know your actual use then you know how much panel you need. 25 amp hours / day requires roughly 100 watts of panels. I think you'll quickly find that you either need a big permanent installation OR you will only be able to support a small fraction of your needs with a couple of hundred watts of portable panels. (We covered about 25% of our needs with 160watts in the tropics.)
If you do get into larger panels...suggest you also get an MPPT regulator to maximize recoverable output from the panels. (MPPT Solar Charge Controllers from Midnite Solar, Outback, Morningstar, BZ - Blue Sky Energy, Solar Boost 2512iX, MPPT Charge Controller, 25 Amp, 12 Volt, SB) It will pay for itself in the first year.
