12 Volt DC charger for laptops and other devices

This device will allow you to charge devices in the 15 -24 volt range at around 3 Amps.

12 V DC-DC charger with adapters for laptops and other devices 15-24 volts

This is a much more efficient way to convert stored energy in a battery to stored energy in you laptop( or to run another device) rather  than through an inverter.

When looking for one of these adapters  (which there are many designs)  look at the adapter tips to make sure they will fit the devices you intend to use it to power.

Make sure the voltage is switchable and matches the voltage you need for your devices.

Not every possible voltage is supplied, common voltages are:  15 16 18 19 20 22 24

Many devices are voltage tolerant to some extent, if need be 1 or 2 extra volts work, if you cannot supply the exact voltage.

Make sure the power rating of the adapter is more than the power rating of the the device.

Check the polarity of the device and charger, usually the outside shaft of the adapter is negative (-) whereas the tip or inside is positive(+). Some adapters allow polarity changes on the tips.

The rating for the adapter can be between 80 and 150 watts.

The easy way to determine the power rating is to look at the AC adapter of the device and multiply the DC voltage and current together and that will be the power rating.

Cost 80W  $25

Cost 150W $120

Cost of an obscure tip $3, time to find one, up to 6 months (be warned).

The sensation of success after a long determined hunt, priceless?

Charge a phone virtually anywhere kit.

well you’ll need a power supply like a 12V battery or a solar panel but with this equipment you have a lot of options.

iLuv USB car adapter

USB with 10 different phone charger connectors. ‘The octopus’

Make sense? I hope so.

so with these 3 items you are able to convert any 12 Volt battery (or 12 Volt solar panel) into a phone charger in a less than a minute.

cost of items about $25,being able to make that call or access that data, priceless?

Universal USB power

iLuv USB car adapter

If you need USB power and you have access to a car or a car cigarette lighter plug that has power, this is precisely what you need.

I really liked how this example appears to be thumbing its nose at copyrights of Apple and Microsoft XboX.

Some models are tolerant of input voltages from 12-24 volts some are not.

Some models advertise what level of current they supply, 1 Amp is common.

Input 12V-24 DC output 5V DC 500-2100mA

these devices only supply power to the USB device not data, this device will not allow you to ‘download a car’ or some other wizardry.

Cost: about $10 for electronics and car accessory shops. Cheaper models may be available with lower output current.
