30-Day Warranty
Add the optional 30-Day Warranty to your order for extra peace of mind. It extends your coverage against manufacturing defects - like a faulty heating element, an unresponsive controller, or failed stitching - from the standard 7 days to a full 30 days from delivery. If your robe arrives faulty, or stops working properly under normal use within that window, we'll replace it free of charge - no hassle. Just reach out with your order number and a quick photo or video, and our team will take care of it. The warranty applies to the original purchaser and covers manufacturing faults only (not misuse, accidents, or normal wear and tear).
How do I wash it?
Very easy! Unplug it, detach the controller, and machine wash cold on gentle — then hang it up to air dry so the fleece stays as soft as day one. No wringing, no tumble dryer: the carbon heating elements are made to handle a wash, not a spin cycle.
Loved by 2000+ Heated Grumps
"My mom hasn't stopped talking about it."
Got it for her because she's always cold but hates fussing with space heaters. She just wraps up, turns the dial, and she's warm. Best gift I've given her in years.
"Warmer than I expected for the price."
Was a little skeptical about the heated part, but it actually gets toasty and the levels make a real difference. So soft and it covers me head to toe. No more cold feet on the couch.
"Perfect for freezing movie nights."
Our living room is always cold and this fixed it instantly. I turn it on, wrap up, and I'm out within twenty minutes. Literally the softest thing I own now.
FAQs
Does it need to be plugged in?
Nope - that's the best part! Heated Grump runs cordless off a USB-C power bank, so there's no cord tying you to the wall. Walk to the kitchen, curl up on the couch, wander the house - it heats up wherever you go. The bank tucks right into the robe's pocket, and when it's low you just recharge it like your phone.
We sell the correct power bank for it separately - add it at checkout and you're set. Already have a 20W (or higher) USB-C power bank at home? That'll work too!
And because the power isn't sealed inside the robe, there's no built-in battery to wear out and take the robe with it - the bank is separate, replaceable, and easy to swap.
What size should I order?
You don't need to guess - one size, and it fits nearly everyone. Heated Grump is a generous full-length hooded robe, intentionally roomy so it wraps over whatever you're already wearing and covers you head to toe, feet tucked in and all. Nothing to measure, no size to pick, no getting it wrong.
How long will the heat last?
Up to 3 hours on a full charge with our power bank on high - and longer on the lower heat settings, since they draw less power. When the bank runs low, just recharge it like your phone or swap in a second one and keep going. Using your own 20W USB-C bank? Run time depends on its mAh - the bigger the bank, the longer the warmth.
Is it safe to wear?
Yes! It's built for it. Heated Grump runs entirely on low-voltage power from a USB-C power bank - the same kind of power that charges your phone - so there's no wall current anywhere in the robe. It has overheating protection on the circuit and 6 timer settings, so it manages itself and shuts off on its own. Doze off on the sofa and it's got you. Like any heated garment, we wouldn't recommend sleeping in it all night - it's made for cozy evenings in the chair.
Is it a good gift?
It might be the easiest gift you buy all year. One size means no awkward "what size are they" text, it works for basically anyone who owns a couch, and the hood makes it the one they'll actually unwrap and immediately put on. It's the rare gift that's funny and genuinely used all winter.
How many heat settings are there?
Three. You get 3 temperature levels running from a gentle 86°F all the way up to a toasty 122°F, so you dial in exactly how warm you want. It reaches temperature in about sixty seconds, so you'll know right away you've found your level.
