I've also learned to take ice packs along - to put in the car seats so the hardware doesn't burn tender flesh. It's amazing that the electronics survive such harsh conditions, but they are tested for just that environment. I used to run some of the test equipment for microships going into cars; it's a serious test!
Max, the manufacturer recommends plugging it into the wall because the charging unit has overtemp protection, while the 12V socket connects directly to the unit's internal battery. The instructions (I actually read them this time!) say to limit direct charging to three hours, or the battery could explode.
@kfield: Does your emergency bow tie happen to be a clip-on number?
To be honest I'd never looked (it was a present) ... but I just opened the can and it is indeed a clip-on ... .that will come in handy if I happen to be wearing a T-Shirt when the emergency occurs! :-)
@Polyspace: It has a permanent home in the van, now. We can charge it from a home outlet, or a cable from the car's 12V socket while driving around. Convenient, and blessed peace of mind!
I agree about th epeace of mind -- mine goes with me everywhere -- I didn't know you could charge it from the truck's 12V socket while driving -- I just take it out of the truck on the first day of each month (the evening if it's a work day) and plug it into the wall and leave it overnight to "top up" as necessary.
I have one of those portable jump starters with the USB, light, and compressor. It is a lifesaver when you're ready to check out of the hotel and find that one of the kids left the van's light on all night, draining the battery. It has a permanent home in the van, now. We can charge it from a home outlet, or a cable from the car's 12V socket while driving around. Convenient, and blessed peace of mind!
@Max....."hearing the news about Zimbabwe..." this election has possibly the best chance of all the recent ones of really being free and fair (in which case Mugabe is out). However Mugabe by his own admission "Has degrees in violence" and is a past master at rigging elections. Be interesting to see what happens, especially if he gets himself in again. The people are in no mood to be cheated. It's an irresistable force and an immovable object scenario....
"I wonder how many of the folks who originally hailed Robert Mugabe as a hero are still happy with him after all this time..." Just about Zero. I never thought he was a hero, though after he got in he had the chance to be seen as one, but he blew it. The election that got him in had massive levels of intimidation, which the Brits chose to ignore as they wanted to get shot of the Rhodesian problem, it had been a thorn in their flesh for 15 years. For duplicity and underhandedness you can't beat British governments (hope you have no pollie rellies :-)
Translation: Pollie rellies = Politician relatives (think this is Australian slang, do you use those terms in UK or USA?)
