Traveling with Too Many Chargers?

MotorMachineMercenar wonders: "I just took a roadtrip over a long weekend and noticed that I need to lug around too many chargers. I have a charger for my cell phone, Nintendo DS Lite, my two digital cameras and an iPod. Sometimes I will have one for a portable HDD and laptop. In addition I have to carry a plug converter as some of them have been bought overseas. That's up to eight gadgets just to give juice my power-hungry devices, and they take precious space and weight in my bags. Is there any way to limit the number of chargers without gimping my roadwarrior gear? Most devices have more or less fixed batteries, 'smart' chargers and proprietary plugs, but is it possible as DIY, or is there an existing product? I'd like to see a universal charger for which plugs for any current device with the flexibility to add more in the future. What are the limitations and caveats with 240 vs 120, wattage, cutting and connecting cables, and so forth?"

    I use Igo and USB cables to charge my devices. Igo junk is available at a lot of retailers. There are varying power source and wattage ratings of the chargers, including air/car/110~/220~ power supplies that automatically adjust voltage and current, and can charge four or more devices at once if necessary. It is based on tip adapters that deliver power specific to their respective devices. They are pretty fast to make new connectors.

    There are also the alkaline/lithium battery powered auxillury chargers, most of which are universal with multiple connecters. You can also use the solar chargers, most of which include a DC car socket.

    I think that sooner than later, everything small will charge from USB and everything larger will have automatically switching power supplies that can run from any typical power source without adaptation.

Get a new cel or other device? $10 for a new tip - RadioShack and others have them in major malls, you can even buy them in airports if you lose a tip. eBay often offers them for $10 per tip from various sellers.

      I even have a tip that works with my battery charger - works with AAA, AA and 9V batteries. Best present I have had in quite a long time. It's got a carrying case, takes as many different tips as you need, and works on AC (US), DC (car charger) and airline charger. It's awesome to charge up my cel between flights - ON the flight!

A Linksys hardware firewall device needs approximately 1 amp at 12 volts. That means that if all the other devices on the shelf also need that amount of power (and they definitely don't) then I've got an awful lot of power to spare to run my 4 USB drives, my Epson scanner, my LCD monitor, my external DVD burner, my speakers, my cell phone charger, my battery charger, and the the other switches and hubs. One nice ATX power supply can do it easily.

It's just difficult to make successfully because a standard home doesn't have the 2 8-port switches and the DSL modem and the home router running continuously making sure it has enough load to run properly. Even then, I'm sure you've heard of the troubles some power supply makers have had recently, because they design them to run with a certain amount of 5V load to go with the 12V load, and modern CPUs and video cards use disproportionate amounts of 12V power.

  31. Universal AC adapter? by evilviper · · Score: 1
    I have a charger for my cell phone, Nintendo DS Lite, my two digital cameras and an iPod.

    I have a question for you... Has everyone in the world forgotten about universal AC adapters?

    Seems like they were pretty common in the 80s, but somehow everyone has completely forgotten about them.

    It's pretty simple, you buy the universal AC adapter, select the voltage and polarity, and plug-in the tip that fits your device (for some odd plugs, you may have to buy the appropriate tips seperately).

    Sometimes I will have one for a portable HDD and laptop.

    The laptop is going to be the only problem... Laptops use so much more power than other devices, that it is prohibitively expensive to get a universal adapter, or even replace your bundled adapter. If you lost or destroyed the original though, it might be better to go with a universal notebook AC adapter too, but the price is prohibitive.

      Don't do this. The ones I've seen are rated for less than 1000mA (usually only 500mA for the cheap ones) which isn't even close to enough for any recent gadget. For example, my MP3 player draws 1500mA, my PDA draws 2400mA. If it is not rated for the current necessary, the adapter may overheat, possibly enough to start a fire.

      The universal laptop adapter is a safe bet, but, as the parent poster pointed out, is kind of pricey.

      I see what you mean, but those adapters, while very practical for older electrical devices, are no longer truly "universal." The "tip" you need for a Nintendo DS (I have one) is unlike anything available in "universal" sets, and then there are the fantabulous inventions cell phone makers have come up with. It seems like each one is different from the other -- I had a friend who had to replace his cell phone charger, and to our surprise, the same manufacturer had different charger models for their different cell phone models (it seemed to change by model family). You can't just buy the tips separately, I'm afraid. (That said, I would be happy to be proven wrong, since I have the same multiple-charger problem as the poster.)

  35. Too many DC plugs by otter42 · · Score: 1

    There are too many chargers and plugs, you're absolutely correct. This problem will probably get worse and worse until a gov't has to step in and regulate the power plugs. More and more businesses are building proprietary plugs for simple 5V, 9V, 12V, and 19.6V adapters. Witness Dell with the needle thing center electrode and octogonal shell, and Nintendo with it's odd trapezoidal plug. It's quite obvious that they're doing this because of buyer lock-in, and not for anything approaching the real needs of the product.

    DIN, ANSI, and all the other standards bodies have long ago defined reasonable specs for these plugs, which brought prices down because of manufacturing en masse. Now that it's so cheap to custom make these plastic bits, businesses are looking at it on the long term and realizing that buyer lock-in provides them with more money than they'll save by chosing the cheap standardized connector.

    The problem is, how to go about this? Gov't regs for technology are Bad (TM) things, and certainly prevent innovation. However, Dell is hardly innovating with a plug that is *more* likely to be broken or bent. Maybe one or two good class-action suits would scare them back into line so that they only develop a new DC connector when there's real innovation in it. Like DC connectors with seperate grounds or magnetic power plugs on laptops. (Apple does this, although I have no idea if they were the first or not)

This will be hard to overcome with regulation/legislation as long as they don't get too greedy with their pricing model so they avoid litigation and customers don't think about TCO.

    yes, it is possible to use a single regulated supply for all devices that run on the same voltage. in the case of my portable electronics, it's almost universally 5VDC, which is also what is used for power over USB. if you are handy enough with a soldering iron to put the various output plugs (barrel connectors and so on) in parallel, one sufficiently robust supply can power them all. to calculate the output wattage needed, add the maximum power draws of the loads you expect to plug in at once. if not listed, the latter can be measured with the DC ammeter portion of any multimeter. for reasons of weight you will probably want a switching supply rather than linear (which includes a large transformer). many supplies are prewired to accept (say) 100-240VAC, 50/60 Hz, so they are useful worldwide as long as you can get it into the wall. one possible variation is a more complex supply with multiple output voltages (e.g. 3.3v, 12v, etc.). NB, regulating a small amount of 3.3V power out of 5V is close to trivial with a regulator IC. hope this helps.
