Power is one of those things that does not seem like a big deal until it becomes one. If you own a Coleman Lantern 17B or 17R, a better solar and power setup can make camping easier, quieter, and a lot less stressful. It is not just about off-grid camping either. Better power management helps whether you stay at full-hookup campgrounds, use your trailer at home before a trip, or spend weekends without shore power. Because these trailers use a 12V refrigerator and have built-in USB A + C plugs, battery health matters more than a lot of people expect.
The nice thing about the 17B and 17R is that they are small enough that you do not need to go overboard. For most owners, the best solar and power setup starts with a good 30 amp surge protector, a simple adapter for home use, and then either portable solar, a battery upgrade, or both depending on how you actually camp. Keystone’s general SolarFlex overview frames RV solar in the same progression, starting with battery protection and 12V system support, then stepping up into bigger off-grid packages with more collection and inverter support.
If you are already setting up your trailer for the season, this page also pairs well with First Trip Checklist for the Coleman Lantern 17B / 17R, Must-Have Coleman 17B / 17R Upgrades, How to Install an Electric Jack on Your Coleman Lantern 17B / 17R, and Coleman 17B / 17R Owner Resources.
What I would focus on first
For a small trailer like this, I would break solar and power upgrades into four simple categories.
- First, protect the trailer when you plug into campground power.
- Second, make it easier to plug in at home.
- Third, improve battery capacity if you camp off-grid often.
- Fourth, add portable solar if you want longer battery life without running a generator.
That approach keeps things practical. It is a lot better than buying random power gear without thinking about what problem you are actually trying to solve.

Best surge protector for the Coleman Lantern 17B / 17R
Amazon pick:
Power Watchdog Smart RV Portable Surge Protector 30 Amp on Amazon
If I were starting from scratch, this is the first power product I would buy for a Coleman 17B or 17R. Amazon’s current product page says it offers 3,000 joules of surge protection, advanced circuit analysis, emergency shutoff, and smartphone monitoring for voltage and amperage. For a small trailer with a 12V fridge, LED lighting, and other voltage-sensitive gear, this is one of the smartest ways to protect what you already have.
Best adapter for plugging in at home
Amazon pick:
Camco Power Grip 30A to 15A Adapter on Amazon
This is one of those small purchases that ends up getting used all the time. It makes it easier to plug your 17B or 17R into a regular household outlet while packing, cooling the fridge, checking systems, or doing light prep in the driveway. Camco’s current Amazon listings show both its 15M/30F PowerGrip adapter and the 30A to 15A Power Grip RV adapter as active products.
If you camp mostly with hookups, a surge protector plus this adapter is honestly the most useful starting combo for most owners.
Best portable solar kit for the Coleman Lantern 17B / 17R
Amazon pick:
Renogy 200W Portable Solar Suitcase on Amazon
For portable solar, this is one of the strongest options to put on the page. Amazon’s current listing says it is a plug-and-play 200W suitcase kit with a waterproof 20A Voyager charge controller and adjustable kickstands. That makes it a really practical fit for a small trailer because it is easy to store, easy to deploy, and powerful enough for light to moderate off-grid battery charging without jumping straight into a full roof-solar project.
This is the kind of solar setup that makes the most sense if you camp in provincial parks, national parks, or quieter off-grid spots and just want to extend your battery life instead of building a huge system.
Because the 17B and 17R both include full pass-through storage, you also have a realistic place to keep a portable solar suitcase when you are not using it.
Best lithium battery upgrade
Amazon pick:
MARSENERGY 12V 100Ah LiFePO4 Battery, BCI Group 24 Size, on Amazon
If you want a real battery upgrade for a Coleman Lantern 17B or 17R, this is a solid option to use on the page right now. Amazon is currently showing Add to Cart on this listing, and the product page describes it as a Group 24 12V 100Ah LiFePO4 battery with a built-in 100A smart BMS, RV and solar use, and dimensions that match Group 24 battery-box fitment. The listing also says it weighs about 21 lb, which is a big drop compared with many lead-acid batteries and one of the main reasons lithium works so well in a small travel trailer.
For a Coleman Lantern 17B or 17R, this kind of upgrade makes the most sense once you know you want more off-grid flexibility. If most of your camping is at serviced sites, I would still put a surge protector and home power adapter first. But if you camp off-grid more often, a 100Ah Group 24 lithium battery is one of the cleanest upgrades you can make.
Best portable power station for extra flexibility
Amazon pick:
Jackery Explorer 1000 v2 on Amazon
A portable power station is not the same thing as upgrading the trailer’s built-in battery system, but it can still be a really useful add-on. Amazon’s current listing says this Jackery unit has 1,070Wh capacity, 1,500W AC output, 3,000W surge peak, and a compact 23.8 lb build. That makes it a strong option if you want flexible extra power for electronics, charging, outdoor gear, or emergency backup without modifying the trailer itself right away.
This makes a lot of sense for owners who want a simple stepping stone into portable power before deciding whether they want to upgrade the trailer battery, add solar, or both.
Which solar and power setup I would choose
If I mostly camped with hookups, I would start with the Power Watchdog and the Camco adapter. That covers the two most common real-world situations: protecting campground power and being able to plug in at home.
If I wanted a more off-grid-friendly setup, I would add the Renogy solar suitcase next.
If I camped off-grid regularly, I would move to a lithium battery after that.
If I wanted extra flexible power without changing the trailer too much, I would add a Jackery-style power station.
That order makes the most sense to me because it solves the everyday problems first, then builds upward from there.
How to think about solar on a small trailer
The mistake a lot of people make is assuming solar has to mean a big permanent system right away. It does not. Keystone’s SolarFlex overview makes the same general point by breaking RV solar into stages, from prep and battery protection up through larger, inverter-based off-grid systems. On a small trailer like the 17B or 17R, starting with a portable solar suitcase is often the easiest and cleanest move.
Portable solar is easier to store, easier to upgrade later, and a lot easier to live with if you are still figuring out how often you actually camp without hookups. It also lets you park the trailer in shade and move the panel into the sun, which is a real advantage in campgrounds with trees.
That is a big reason I like portable solar so much for the 17B and 17R. It fits how a lot of people actually use these trailers.
A few practical power tips for the Coleman Lantern 17B / 17R
Because these trailers have a 12V refrigerator, battery condition matters more than people sometimes assume. Even if you are not using a bunch of other electronics, the fridge alone makes good charging habits more important. Both current model pages also list one 20 lb propane tank, which means propane helps with furnace and cooking use, but it does not remove the need for healthy 12V power.
If you are also adding convenience upgrades that depend on the battery side of the trailer, this is a good time to look at How to Install an Electric Jack on Your Coleman Lantern 17B / 17R. A better power setup makes all of those everyday upgrades easier to live with.
I would also keep your power gear organized in one place. Surge protector, adapter, extension cord, and any solar cables should stay together so setup is quicker and less annoying every trip. For more tips on storage check out our Storage for the Coleman Lantern 17B / 17R page.
Final thoughts
A good solar and power setup for the Coleman Lantern 17B or 17R does not need to be complicated. For most owners, the smartest approach is to protect shore power first, make home power easier second, then add portable solar or a battery upgrade based on how often you camp off-grid.
If I were building out this trailer today, I would start with the Power Watchdog, add the Camco adapter, then decide between the Renogy suitcase and a lithium battery depending on how often I was camping without hookups. The Jackery is the extra-flexibility option if you want portable power without jumping straight into a full trailer battery upgrade.
