I often rant here about the need for better universal power supply technology. And there is some progress. On a recent trip to Europe, I was astounded how much we took in the way of power supply gear. I am curious at what the record is for readers here. I suggested we have a contest at a recent gathering. I had six supplies, and did not win.
Here’s what the two of us had on the German trip in terms of devices. There were slightly fewer supplies, due to the fact several devices charged from USB, which could be generated by laptops or dedicated wall-warts.
- My laptop, with power supply. (Universal, able to run from plane, car or any voltage)
- Her laptop, with power supply.
- My unlocked GSM phone, which though mini-USB needs its dedicated charger, so that was brought
- My CDMA phone, functioning has a PDA, charges from mini-USB
- Her unlocked GSM phone, plus motorola charger
- Her CDMA Treo, as a PDA, with dedicated charger
- My Logger GPS, charges from mini-USB
- My old bluetooth GPS, because I had just bought the logger, charges from mini-USB
- My Canon EOS 40D, with plug in battery charger. 4 batteries.
- Her Canon mini camera, with different plug in battery charger. 2 batteries.
- Canon flash units, with NiMH AA batteries, with charger and power supply for charger.
- Special device, with 12v power supply.
- MP3 player and charger
- Bluetooth headset, charges from same Motorola charger. Today we would have two!
- External laptop battery for 12 hour flight, charges from laptop charger
- Electric shaver — did not bring charger as battery will last trip.
- 4 adapters for Euro plugs, and one 3-way extension cord. One adapter has USB power out!
- An additional USB wall-wart, for a total of 3 USB wall-warts, plus the computers.
- Cigarette lighter to USB adapter to power devices in car.
That’s the gear that will plug into a wall. There was more electronic gear, including USB memory sticks, flash cards, external wi-fi antennal, headsets and I’ve probably forgotten a few things. read more »
