Loop B flooded twice in nine seasons, but only one storm system ever knocked the shore power out across the whole loop for two straight days. It came through on a Friday night in early May, the kind of storm that snapped a limb onto the line outside the campground office before most of that weekend's campers had even finished backing their trailers into their sites. By Saturday morning every pedestal on my loop was dead, forty-some sites full of people with nothing to charge a phone or run a lantern, and a full holiday weekend still ahead of them, with the district office telling me a repair crew wouldn't reach us until Monday at the earliest.

I'd bought the Jackery Explorer 300 Portable Power Station back in April, mostly out of curiosity after one too many campers cornered me at the entrance station asking if I had an outlet somewhere, anywhere, because their phone had died overnight and they needed to check a work email before Monday. I hadn't expected to need it myself. I plugged it in once at my own site to make sure it charged the way the box said it would, then it sat behind the seat of my Tacoma for three weeks until that Friday storm proved me right.

By Saturday afternoon I'd walked the loop twice checking on people, and the same two problems kept coming up. Phones were dying, and a man at Site 14 was getting quietly panicked about his wife's CPAP machine with no power to run it that night. I brought the power station over myself, plugged the machine into the AC outlet, and it ran clean through both nights without so much as a flicker. That's a small unit doing a small job well, nothing dramatic, but I watched that man's shoulders drop the moment the machine started its normal hum instead of staying silent.

That wasn't the only site with a real problem instead of just an inconvenience. Two sites down, a young couple had a baby whose sound machine and bottle warmer both ran off the pedestal, and the camp store's little backup generator had already been claimed by the office for the two chest freezers full of firewood-bundle ice packs. I ended up rotating the power station between Site 14 overnight and their site for a couple of hours in the evening, which meant more walking for me, but nobody on that stretch of the loop went without something that actually mattered to them.

I've seen campers ration ice for two days without complaining once. Take away a way to charge a phone or run a CPAP overnight, and that's when a holiday weekend actually turns into a bad one.

What happens at your site the next time the power goes out?

The Jackery Explorer 300 Portable Power Station holds a 293Wh LiFePO4 battery, enough to run lanterns, charge phones, and keep a CPAP machine going overnight without shore power. Check today's price on Amazon before your next trip.

Word got around the loop faster than I expected. By Saturday evening I had campers walking up to my site with phones in hand, asking if they could get twenty minutes on the outlet before dark. I set it up on my own picnic table like a charging station and let people rotate through, three or four devices at a time, while I kept walking my usual checks. It never ran low. I charged phones, two camp lanterns, a kid's tablet that someone swore would prevent a meltdown, and that CPAP machine again the second night, and the Jackery still had capacity left Sunday morning.

Part of the reason it never ran dry is that I topped it off from my truck between rounds. The Tacoma's engine was running anyway while I drove the loop checking on people, so I'd plug the power station into the 12-volt outlet on the console for twenty or thirty minutes at a time and get a decent chunk of it back before the next round of charging requests started up. It's not a fast way to recharge a battery, and I wouldn't plan a trip around it, but as a stopgap during an actual outage it kept the whole thing from ever going fully empty.

I want to be straight about what it isn't. This is not a generator that's going to run your camper's air conditioner or keep a full-size fridge cold through a heat wave, and I'd never tell a camper otherwise. It's a 293-watt-hour battery, good for small electronics and a handful of low-draw devices, not for anything that pulls real power. If you're picturing it running your whole rig off grid, that's the wrong expectation and you'll be disappointed. What it did on my loop that weekend was smaller than that and more useful than that, both at once.

What stuck with me wasn't the storm, storms come through every season. It was how many people on that loop had never once thought about what they'd do if the power just stopped, because it never had before. I've written up how the Jackery held up over a full season of regular use in my full season review, and if you want the blunter version of where a 293Wh battery actually falls short, I laid that out in an honest review of the tradeoffs.

What I'd Tell You If We Were Sitting at My Kitchen Table

If you asked me over coffee whether you need one of these, I'd tell you the same thing I told half of Loop B that weekend. You don't need it for a normal trip where everything goes right, and most of your trips will go right. You need it for the one where the power's out, your kid's tablet is at four percent, and somebody two sites over needs their CPAP running by dark. That's not a big ask, and it doesn't take much gear to answer it. It's just having an answer ready before the storm asks the question.

After watching it carry a CPAP machine and a whole loop of dead phones through a two-day outage, the Jackery Explorer 300 Portable Power Station earned a permanent spot behind the seat of my truck. Check today's price on Amazon and see if it's in stock before your next trip.
