Question: Will this work in old model flipper, without an on/off switch?
Document: This adapter is essential to charge the Yankee Flipper bird feeder. We've had our feeder for years and needed a new battery. In researching which battery to get I noticed that the old adapter would not work with the new battery. I only ordered the adapter because I saw another review pointing this out....who knew! So, we have a new battery, correct adapter and all is working well.
I ordered a new battery. thanks to the reviews I saw remarks that old charger would not work on new batteries. SO I ordered both and was able to chage new battery the day it arrived
After several years of use the old battery stick would no longer hold a charge, so I had to order a new battery. Then I discovered I also had to purchase the new charger. I like the Yankee Flipper bird feeder but was annoyed that I had to purchase the new adapter to charge the new battery.
I needed a replacement and Amazon was the ONLY place I could buy it. I was glad to have found it since the squireels would have taken pver the bird feeder without it.
We have tried it a couple of times, and it is not charging the Flipper feeder at all. Not sure why.
We love our yankee flipper bird feeder since it is the only thing we've found to keep the squirrels for eating the birdseed.
No issues at all, works as it should. My Droll Yankee Flipper when fully charged functions for months, keeping the birds fed while happily flipping off squirrels and chipmunks ;-)
Bought this and a new battery to keep our Droll Yankee Flipper in action and were pleased. Its fun to watch the squirrels go flying when they try to feed at this one.
Our Yankee flipper was the perfect answer to the droves marauding squirrels at our feeders until the battery died. We couldn't locate the original but bought one online and now we are once again protected from the furry felons.
came immediately, and worked fine and dandy, now the squirrels and chipmunks are flipping again. They fly thru the air with the greatest of ease. The flipper is great, within days they stay away because it does flip them, and the birds are fine.
Answer: We have the model with the switch and it works great. I think as long as the plug,fits inside if the recharger unit it should recharge. Maybe you should check on the return policy if it does not fit.
