Translucent AAA-to-AA Type Battery Converter Cases (4-Case)

Pros: well.. they are very useful because i have plenty of AAA batteries but also have to use AA. having these cases i have flexibility. they are solidly built and they have nothing which can broke and go out of order

Cons: up to now no cons

Other: basically they do what they should do. i tested them with two devices which need AA batteries. probably there are devices which require AA but these cases will not fit them (i mean size), bat at the moment all cases fit the devices i used to test them. anyway one should remember that devices which are for AA are power hungry and AAA batteries have 3 times less energy than AA

Pros: Low price, easy to use. Good material. You can charge aaa rechargable battery with normal aa charger. I use in a wireless mouse, good contact, nothing problem. I never found something like this in my country (Hungary). Light weight (plastic). Very useful.

Cons: Nothing special.

Other: I got 30 pcs aaa battery, I must use them in cam or in a mouse. If you have aaa battery, but you need aa this is the best choice. AAA rechargable batteries are cheaper then aa, i think. Just buy it and use. They save me a lots of money.

Pros: i bought several AAA batteries but have electronics that use AA. my AA batteries ran out and i only have AAA left, with these i dont need to waste $$ buying more AA in bulk where they just sit, i can use my AAA to power my AA electronic they work great, open them up, pop in AAA, close and put in whatever takes AA and it works flashlights, wireless keyboard, remotes

Cons: none, work great

Other: got AAA's? need AA? then you need this

Pros: Long sought such a thing. I bought a few hundred alkaline AAA batteries with past their expiry date (yes they will, it is not fish the same ))))) for a couple of dollars. And nowhere to apply. Certainly in the lights and other devices with high power consumption is not appropriate. But in remote controls and similar devices at the time. You can buy AAA batteries, and connect through these transitions.

Cons: Slightly higher price.

Other: Thing specific, needed not all .....

Pros: Well, they just work!
They are _very_ slightly smaller in diameter than some "real" AAs so actually fit better in a couple of my flashlights which have slightly small ID barrels.

Cons: No significant cons.
Obviously, an AAA battery entombed in this AA carrier won't give the same life as a real AA -- but that's to be expected.
The mating parts of the "snap together" barrel may not last forever, but it's fine for now and I could probably just charge the AAAs in the carrier without opening them.

Other: If you even think these might be useful, toss one pack into your next order to deal with the moment when you need AA and only have AAAs charged up.

Pros: These AAA-to-AA converters are really good. They do not have any of the flaws some other converters can have. They are very well built and they seem durable. Their negative terminal is a metal plate with a spring (some other converters have just a hole). The two halves snap firmly into place, so the converters stay closed when their spring is compressed. The size is perfect and should fit any AA-operated device (some other converters are too large).

Cons: The two halves snap firmly into place, but a screw thread may have been better (more durable).

Other: A good buy.

Pros: Does what is promises. Easily use an AAA battery in most devices otherwise taking an AAA. Do however take reduced capacity and power capability into account. So don't expect to use them in a digital camera. I don't consider this a con as it's a physical barrier and not a design flaw. For cordless mouses, keyboards, remotes and the like it's however *perfect*

Cons: It seems to be a little longer than a regular AA which may be a problem in some devices. However I believe in most devises this will not be a problem.

Other: Especially useful if you like me for some reason always seems to gather endless amounts of AAA while your cordless mouse etc. all takes AA.

Pros: Perfect "AA" fit. I use them on a DirecTV remote. On those remotes the majority of rechargeable AA batteries get stuck and are not able to make contact. Whit this converter you can use a AAA battery and solve that issue.

Cons: none

Other: Easy to use and gets the job done.

Pros: Simple yet convenient and effective. This also helps when I need it for many of my appliance at home, the clock, tv remote, massager etc.. I find it useful especially when I do not need to carry out many batteries when I go camping. I can carry more when I bring my radio along on weekends.

Cons: It can be easily squashed inside my bag. The plastic seems thin for a start, but for lightweight, I think this is acceptable. Quality not there, plastic cover.

Other: Get one now, or share it with your friends, they will like it too.

Pros: -Really useful item -Just put the AAA battery inside then close the case and you have a AA baterry -Translucent color is very cool

Cons: -The case it is kind of small for some devices but you can just pull the "Spring-loaded" of your electronic device and the battery will fit just fine -Not very useful for digital cameras or other devices that use a lot of energy, if you use new AAA batteries maybe you can take some pictures but they will run out of energy pretty fast

Other: -Very nice item to have in your tool box, you never know when you will need AA batteries
