N00b asks, what's needed to just run a common extension cord from RV park 15a?

[Munchmeister]

N00b alert. Long time non electrical camper here. Haven't been in a campground in years and when I was, it was tent camping. I purchased a new shell FWC (no electrical) and plan a road trip, where I'll be staying at some campgrounds/RV parks, every few days. I'm going to have a Goal Zero Yeti 400 along and want to charge it during stays where I can get 15 or 30 amp service. What kind of adapter do I need to plug into electrical service panel at an RV or campground that provides, say, 15a service so I can just plug in a common extension cord that I'll use to recharge the Yeti, using it's wall plug? Or do campgrounds just have 120v plugins? If they don't, is there a type of adapter that can be used?

The built-in Yeti charger is very very weak and slow, overnight may not be enough.

Get a proper charger like ProMariner or Sterling with adjustable setpoints, as high amps as you can afford, IMO at least 40A.

A regular 15-20A 115AC outlet is fine.

If the batt is LiFePO4 set it to 13.8V max, and make sure to STOP charging when charge amps decline to near 2A, going past that (lower amps, higher SoC) is harmful to longevity. Don't use the canned LFP profile.

When not cycling store the Yeti 80-90% discharged, storing it full will hurt longevity.

Don't EVER charge it when temps get down to freezing, discharging can go a little lower, but better to keep it over 40°F.

Don't discharge all the way down, best to use an LVD that cuts off at 12V or a little higher.

If it's some other flavor of Lithium Ion, call and ask them for the details.

A regular (outdoor) extension cord will work fine. I like the ones with the indicator light built into the female end so you know you have power.

Most of the time power pedestals have 30A and 15A plugs. On the rare occasion that there is only a 30A, good idea to have a 30A-to-15A adapter along. You can buy them lots of places, even Walmart.

Campground receptacles are notorious for being miswired if not burnt & buggered from overheating.

• I've encountered burnt plugs and faulty breakers in the park boxes, so I carry extra adapters, extra cords, and extra testers just in case. And, if really needed, an on-board generator, too.
• adapters and extra GFCI breaker should overcome faulty park pedestal equipment
