No. For <$10 you can buy an outdoor, 3-way power cord or a 3 way Outdoor Power Stake.

You'll waste a roll of electrical tape and moisture will still get into that Indoor power strip potentially ruining the power strip , tripping your breaker and possibly messing up anything else on that circuit.

For $10, I wouldn't take that chance but thats just me.....

Thanks for the info. I just looked them up, and for some reason, those products are quite a bit more expensive here ($30+). I would probably still go for it, but the cords are all about 6 feet, and I need 10-12 to reach the other cords around the front of the house.

I was hoping that block heater cords were built to handle the elements, but it doesn’t say outdoor vs indoor on the packaging.

I guess we're a little confused.

You describ plugging an outdoor outlet into a block heater cord which is fine because they're always outdoor rated and water resistant. But then you abruptly mention also using an indoor, home power strip which seems a little odd but maybe we're losing something in translation...?

My block heater cord has a power strip at the end.

Similar to this one but it doesn’t actually say outdoor/all weather, so I wasn’t sure if it should be completely exposed, and get rained/snow on for weeks, which is why I thought using electrical tape might help. I’m just concerned about the power strip sitting on the wet ground as opposed to on the side of a car in a garage where they would normally be used.

Oh, yeah I think you mean your heater cord has a Three-Pronged Head. A power strip is a stand alone, grounded device that plugs into other extenion cords, heater cords, etc. It has multiple, 3 prong plugs and usually an on-off switch + replaceable fuse.

Anyway..uh what makes a heater cord different than a regular extension cord is the thickness and ....I've never heard of a heater cord that wasn't rated for outdoor/all weather.

Let's just assume your heater cord is 'all weather'. If you are concerned about moisture, your biggest risk would be if the end ended up laying in standing water and a little electrical tape wont help that. If you have a stake or something you could zip-tie the end to o its elevated a couple of inches off that ground that be best.

Or not. This is holiday lighting we're talking about. Just be cognizant of it possibly popping a breaker at any point so make sure you don't have something crucial on that circuit, like a fish tank or something...

Thanks for the clarification. I’m probably just overthinking this. I think the thing that worried me a bit was how much cheaper block heater cords are as opposed to a regular extension cord. My 3 pronged block heater cord is 32 feet and was 15 dollars. At the same store, a regular 32 foot extension cord with 3 prongs was 60 dollars or more.

Hrmm. Well my first guess, on the price difference, would probably be the gauge of the extension cord.

Thicker Gauge = More Copper.

More Copper = More Expensive.

16 gauge is the minimum gauge for running a high wattage heater, like a block heater, but that is only considered 'medium duty'. For running generators or high amperage motors you would need heavy duty or ultra heavy duty power cords and those need a lot of copper.

$15 for 16 gauge/32 ft is about right. $60 for a 32 foot cord should be at least a 12 gauge but, idk, sometime getting ripped off is your only B&M option. If that is the case, explore online options for a more fair price...
