Absolutely thrilled with this purchase! The product exceeded my expectations in every way—great quality, well-made, and performs exactly as described. Shipping was fast, and the packaging ensured everything arrived in perfect condition. I appreciate the attention to detail and thought put into this. Would definitely recommend to anyone looking for something reliable and worth every penny. I’m beyond satisfied and would definitely buy again.

Perfect fit and use.I was concerned thanks to some of the “off” reviews - but - I have a Big Buddy (2 burner) heater. This plugs in perfectly snug. Fan turns on immediately and works perfectly. Would purchase again and recommend to anyone needing power for their heater fan.

Runs the fan on my new "Big Buddy" heater (which I don't often use). No idea about durability-yet. Seems to be as good as any other 110 volt to 12 or 6 volt transformet.

Plug fit perfectly in heater socket, fan spins same as with batteries, but no battery expense. Bought this instead of the official Mr. Heater branded adapter, due to the good reviews on this one vs. the terrible reviews of the Mr. Heater adapter (apparently Mr. Heater's used to be good but they changed their supplier, and now they are crap.) Glad I bought this one instead.

Fits the small external battery connector for powering the fan on the portable heater. Great option for saving batteries in the case you need the heat and have electrical power. You'll need the batteries for when the power goes out.There are versions of the Big Buddy heater that do not have an internal fan, and I would expect these also do not have a battery compartment or external connector for the fan power supply. The heater can not use the power adapter if there is no fan.

Have bought other cords. Had to send back or to the store. This is the right one.
