New type of Cell Phone Chargers!

[kiMMie]

OMG! That Kraigomatic is hilarious

[sNyx]

see it, its more of a jump start for your phone to make that one call you just had to make. cuz you know what does ur phone bunk out the worst, right when you need it most

like I think it was 20 turns gets like X amount of volts for like 2 mins of use. lol, interesting non the less

There are a lot of different methods of storing hydrogen at low pressure with a higher energy density.

I dig lithium ions, but they aren't cheap either, especially for high current draws. As far as the hand crank goes as I stated above, this thing has to be made cheap enough for someone to justify buying it, but at what cost to product quality?

Ballard isn't the only one in the world producing fuel cells nor does everyone in the industry work with them :)

note: I was assuming that you didn't work for Ballard :) - and yes I do work for Moli (when im not slackin off like i am right now), although that one's a little easier since we're the only manufacture in North America (at the moment at least)

Those 'compressed hydrogen'-free cells sound pretty cool, haven't heard of them yet. Li ion cells aren't that cheap, but that's only cauz the pack makers jack up the price 10x or more. Although I really can't see mini hydrogen fuel cells costing any less - I would assume that they would cost more simply due to the excessive research put into them, although I could be wrong (wouldn't be the 1st time) since I have no clue about the raw materials/production costs.

it's for emergencies + camping, i'd reckon it would fuck your battery somethging fierce if it's not top quality.

yah, unless it has a current regulator in there it wouldn't matter what quality it was it would still fuck up the battery - i'm assuming that they would put one in there though.

yea can't wait until fuel cell batteries come out, lithium ion's suck, my laptops battery only lasts about half hour fully recharged now :( and they're hella expensive

[baby_bluez]

its definatly one of those inventions that is going to be mocked by the next genereation

"when i was your age i used to have to charge my phone BY HAND" *grumbles* :soak:

that's cauz you have shitty batteries probably made by a shitty company - there's lots of em, believe me, i test them every day, lithium ion's are easily better than any other type of rechargeable battery on the market.

crazy shit... doesn't work for ballard im assuming cauz they laid a bunch of people off not too long ago - some company that takes care of outsourced contracts from Ballard, et al.?

This reasoning makes no sense though...

There's a large number of companies that downsize, that doesn't mean that they don't have anybody working for them.....

Heck, a 15% staff reduction is considered pretty large, no? Which means there's still well over a one in six chance that any given person working for the corp will still have their job after the cutbacks, no?

thats funny yet so dumb. I charge my phone every night no matter what anyways so im fine. although im down wiht the hamster one

mine only last maybe an hour also. its just the same one that comes with the laptops. mine are toshiba and a dell.

its a compaq battery.. came with the laptop. you would think that they would produce quality lith batteries for their own products? it's not an old laptop either i've had it for a year

[dj_precise]

Well the retail price on this from where I saw it was around $14.00.. Thats super cheap compared to other products Ive seen on the market. Theres spare battery packs you can get which are the size of a pack of gum which are pretty much disposable for around $10. Theres little patches that you stick on the battery that prolongs the life of the battery. This is abosolute crap and a waste at $10.
Theres gonna be lots of new gimicks comming out in the near future for batteries and I thought this was the coolest so far.


As for your laptops out there, the reason why your battery isnt lasting so long is because of your charging patterns. One main reason for your battery not lasting so long could be because you leave your charger connected while you are stationed and have it connected even when your battery doesnt need recharging. Doing this will drastically decrease the life of your battery and was the number 1 cause for people buying new ones from me when I was slanging laptop batteries..

Hey pbreak, do you work at Eagle Pitcher??

[bebu*funfun]

i think i saw something similar at the night market over the summer! double a batteries or something. could be quite handy.

You should call it in to Compaq and ask for a new battery... we deal with Compaq exclusively where I work and we're sending stuff back all the time for replacement. Is it still under warranty? Worth a try.

[Leviathan]

lithium ions should last a decent amount of time if handled correctly. My guess is compaq probably contracts their battery making to someone else and brands it with the compaq name.

what department do you work in pbreak? Some people I graduated with from robotics work there.

i work in research (at Moli Energy in Maple Ridge ryan) but i know a few of the robotics guys - not exceedingly well though, mostly just talk to them on lunch breaks and such...

so lets clear the whole lithium ion thing up:

precise is right on the charging thing for the most part - if you float the batteries at their upper voltage limit for extended periods of time they will lose capacity - although this is much more pronounced in certain brands... the thing is that the chargers should have a cut-off that stops the charging process once it has been at the upper voltage limit for a certain period of time - i know my phone does, and thus getting rid of this problem.

The main aspect of my job is dealing with competitor products - reverse engineering and testing - a few of them are really good like LG and Sony, whiles others consistantly suck - like Toshiba, easily one of the worst - probably why your pack sucks Phunk. Only problem is most of the time the pack manufacture is different from the battery manufacture, and they all buy from multiple sources so you can never really know what brand of battery you've got. I have one of the notoriously shitty Motorola C333 phones with the battery that ended up lasting 5 minutes after only 6 months of use - but got it replaced and now it lasts 3 days... so kind of a shot in the dark.

The technology is a lot more complicated than you might think and they are always trying to fit more and more capacity into the same size cell so consistancy really becomes a large issue as well even with the good brands - but this applies to any type of rechargable battery anyway... and if you really still don't like em you can go back to Nickel Cadmium batteries (the ones in older portable phones with the terrible memories).
