Eneloop Panasonic BQ-BS2E4SA C Size Battery Adapters for Use with Ni-MH Rechargeable AA Battery Cells, 4 Pack

These do work, but remember it has a AA battery inside so it is not as powerful as a true C battery

Fantastic product, very easy to use. Great value!

Quite pricey for these pieces of lightweight plastic but well worth it for being able to replace C size Batteries using only 1 AA Battery & one Eneloop C Size Battery Adapter in place of a bulky & also pricey C size Battery. I purchased an 8-pack of the Eneloop C Size Battery Adapters for use with my MR. Beams MB316 Six pack motion sensing lights which of course require 3 C size Batteries per light totaling a required 18 C size Batteries to use & operate all 6 of them, ridiculous that it is in my opinion for such small lights! Anyway, not to mention that I use & purchase only rechargeable Batteries for uses like this which is too a big expense. Therefore, I was able to buy & use only 3 Eneloop C Size Battery Adapters & 3 Eneloop AA rechargeable Batteries per each Mr. Beams motion sensing light versus having to purchase a total of 18 expensive rechargeable C size Batteries to operate these small & silly Mr. Beams motion sensing lights. In the long run & future, these quite pricey Eneloop C Size Battery Adapters will pay for themselves as for we do not have to always purchase expensive & bulky C size Batteries for our electronics anymore thanks to C Size Battery Adapters like these that allow 1 AA Battery to work & become a C size Battery with just 1 Eneloop C Size Battery Adapter. These are great & better than I had expected them to be. Highly recommended if you want to get away from purchasing bulky C size Batteries which also come at a high cost especially for C size rechargeables. Bye Bye C size Batteries & hello to the smaller & more affordable AA Batteries to be converted over to C size Batteries using the Eneloop C Size Battery Adapters.

Great idea and works well but I had to put AA in 'reverse' for my candles. They fit snuggly both ways, so not harm, no foul - they went from 'p.o.s!' to 'these work great' which is why 4 stars.

Why did you pick this product vs others?: Great product works as stated. Worth the money and eneloop batteries work really well and as stated, maintains power even several months in storage of at least 70%. I've tested this several times already and it does in fact do that. Best, brand of batteries rechargeable wise you can buy

Omg, I cannot say enough about these adapters. They save me both time and money. Nothing makes me madder than having to run out to get C-sized batteries only to discover that they don't have any. In the meantime, I have plenty of double AA and rechargeable batteries sitting in my desk drawers. I ordered these adapters from Amazon while looking for batteries. I saw these being advertised and really liked what I heard and saw. I love the great price of these, as well as the fact that they help with our environment. These were something different that would save me time and money. I got them really fast after ordering. Thank goodness for the advertisement otherwise, I would have missed these must have. Save your money and get these and insert your batteries to change your double AA battery into C sized battery. I ordered two packs with the holidays coming fast and the great need for batteries. I had to have something wonderful that would keep more of my money in my pocket. Your wallet will thank you.

Works perfect for UNO Flip Attack Card Game with Launcher Unit which was needing D cells!

Any dollar item adapter will do just as well as this product, imo - however, I feel, if I had to blow money on Eneloop batteries then I would like to show them off, no matter what size battery is needed..

Maar erg duur voor wat het is.

There are only one problem with these C size Adapters and that is the very thick wrapper that solidly encases the adapters so much that it is nearly impossible to unwrap.There is still a x-ac-to knife score mark on my thumb as they slip off the thick wrapper slicing across my thumb. Other than that one complaint the envelop AA battery simply slides into the casing and that is that; no unscrewing a cap and no unhinging the case. It is a solid single piece case that makes the AA battery feel like a C Size battery. Excellent and finely crafted case. There are so many devices that still uses C-size batteries these days, my hand waving sensor garbage can uses 3xC-size batteries, my Alessis Drum kit uses 6xC-size batteries and my sweater shaver uses 4xc-battery. Save your money and don't buy the knock offs buy cheap buy twice.

great way to use AAs in devices that need C batteries

Compré estos adaptadores para ponerselos a un calentador de agua, que para encenderse requiere de baterías y van geniales Prácticamente van 6 meses de uso y sin problema Las baterías son de la misma marca que los adaptadores Super recomendadas!!!

This worked like a charm! Much easier to use common batteries AA than C for just the odd cat toy! Quality is good fit in good worked great. Happy with this product.
