Turn your AA’s into D’s

Are you frustrated like me that you have to stock so many battery types, when they all seemingly have the same voltages? Gadget.brando of Hong Kong solves this problem with their Battery Converter. Simply insert the AA battery (which odds are all over your place) into the converter and you have an instant faux “D” Battery. At a cost of $5.00 owning several of these is a no brainer.
It might be useful, but i think $5 is a bit much. Well at least at my country :)
Yeah, these would work in a pinch…but the whole purpose of the larger cell batteries isn’t for higher voltage (since, yes, AA, AAA, C, D, etc, all are 1.5v) – the larger batteries are so that they can provide LONGER life.
i.e. a device might only require 1.5v, but will draw a higher current, thereby draining the smaller batteries faster.
We used to use a double A and a stack of pennies to fill in when when were short on a D battery.
psh i know how to permanently change your AA’s into D’s. It’s called plastic surgery
Those have been around for years, have been selling them in the shop I work for as long as i can remember
The problem arises when you look at the mah ratings for each size of battery. While D cells have a rating of 20,500, AA’s only have 2,850, or roughly 1/7 the staying power. While these would be a great temp fix when you don’t have any D cells, you’re just not going to see the life you may need out of the device. This could be dangerous if the device is a safety or emergency item.
Yes, C and D cells are annoying, but have you stopped to think *why* the manufacturer has chosen them instead of AA? Larger cells have greater capacity, then are therefore generally used in high-drain devices. A real alkaline D cell will have around 20,000mAh capacity — around 7x as much as an AA. These adaptors might be handy if you’re in a jam and need to power something for a short time, but not really the way to go in the long term..
Thats really cool.
