Emergency Battery Package and Desk Lamp

Featured
Picture of Emergency Battery Package and Desk Lamp
Sometimes your laptop computer, your lamp or even your car need to be powered and what you have are batteries only.

I have had the experience on using 20 AA batteries (packaged in 15V) to jump start my car.

In case of emergency, maybe you can power EVERY DEVICE which you MUST.

In the event I planned to have this many batteries on hand I also plan to have several battery holders and jumper wires on hand to be able to many voltages available easily,and quickly. A good exercise in improvisation though.
us an led lamp. cost is $3 on ebay
An LED lamp is great idea. But if I am going to buy something to have in an emergency, I doubt it would be a $3 LED. The point of this seems to be "use what you have".

But what you will have in an emergency, is what you have planned to have on hand in an emergency. Have lamps, and spare batteries on hand, isn't really different than planning to have this many AA batteries on hand.  Planning on having to improvise is part of the plan as well

This might be valid, but jump starting a car is absolute BS
dragonbtv (author)  LinuxH4x0r5 years ago
I did use it on car's battery once. Next when your battery is not fully dead and the startor can slowly run, only left the staror to car battey and other cable connect to your package battery...
i think that may of just been luck. the pack kept my laptop going for about 12 minutes. i powered it through the dc charger port tho not direct to the battery terminals as the regulator circuit is inside my laptop battery and the charger regulator is inside the laptop.

it would work for a laptop...for only about 5 to ten minutes laptop batteries are about 5 amps the cells are about double the size of AA My AA battery pack compared to my Laptops battery pack makes it look like the AA is a mini version of the large one
It's meant to be a last straw. (duh!)

I gave mine a try and it worked but the aluminium foil was really really hot after.

the key point is to use thim in layers and press them firmly to make them into ONE wire. try to ford them more layers please

Wouldn't this quickly drain your battery? I know my 12v desk lamps are all 50w, they don't sell others.
dragonbtv (author)  awang85 years ago
my bulb coming from IKEA, it is a 12V / 10W only
