USB charging the DSE901

[tribalmasters]

I see Smokester does a USB charger for his ecigs but someone complained on the suppliers forum it takes too long!

I think it may be down to well behaved USB ports that give very little power just enough to ask the connected device what power it needs and of course, the USB charger has no USB electronics to tell the computer to give it the max power!! I am not sure tho. I notice most just chuck out 500ma which is nice.

If the USB works to charge the batteries as fast as a mains charger, I am thinking a powered USB hub is a great way to have many chargers connected at once and ya don't need a computer!!!! The spider picture of many connected chargers from one of them multi plugs to the mains comes to mind tho I cannot remember who posted it!

its not the way usb ports work dude.. they simple supply 5 volts at a theoretical 500 mah max.. the plugged in device controls the power..

a properly designed usb charger should be well up to charging an e cig battery.. my 901 charger puts out 100 mah.. 1/5 the power a single usb port is capable of putting out..

a powered hub should charge a whole bunch of e cig batteries with no problem.. a normal usb port would charge a much larger battery than the e cig one with no problem.. like a 2000 mah one in four hours.. it could blast a baby e cig battery in half an hour.. flat to fully charged..

never believe a word u read on forums dude.. he he he

unless u know and respect the source..

Hmm good point, my 4 year old pocket PC still charges in a few hours on USB and its got a huge battery! My old self-build piece of crap PC I had long ago had one great freature - its USB ports stayed powered even when the computer was off! I bet plugging in 10 ecig chargers would have overloaded the standby voltage from the powersupply just a little I am guessing tho hehe especially being an AMD Craplon, ya know the ones that always had bad capacitors on the motherboard

cheap chinese bad capacitors.. he he

i untill six months ago i ran an amd system.. they had intel beat.. now intel are back in front and sadly amd will never catch up again.. reluctantly i moved back to intel.. my current intel chip is running at 4 gigahertz sweet as a dream.. twice the performance of the best amd has to offer..

once every eighteen months i turn into a computer geek.. gen it all up spend four months as a benchmarking freak on the techpowerup enthusiasts forum doing pretty much like i do here..

when its all done and have have got a machine i know is the tops.. sanity returns i lose interest and i just use the bugger like anyones else does.. he he

thats my five month old score.. trog100.. it will stay near the top for quite some time.. till i have my next geek phase.. he he

I have two of these USB charges which also have wall socket built into it as well.
I thought it would take a lot longer to charge in the computer like some of my other devices because of the power output of USB.
But to be honest it doesn't seem to be any difference whether it's in the USB computer or wall socket in charging times.

 

[trog100]

c-cig china sold straight plug in the wall powered e cigs.. folks said why bother with a computer why not just plug into the wall..

but the thought of connecting myself directly up to the 240 volt mains.. one end in the wall socket and the other in my mouth with any cheap chinese made device kinda horrifies me

it is kind of amusing thow.. i see old cartoon like images in my mind of a chap with lightening flashes coming out of his head..

an electrifying experience possibly.. he he he..

LOL!! I would love one of those adapted for the 901, tho maybe the usb one and then...and then comes a REAL use for that overpriced iPod USB charger - the one with just an USB port on the front!

iSmoke don't breathe this!

Haha you will laugh at my machine! Its ermm dare I say it a Dell. It has a slow old 1.6GHz pentium 4 in it tho luckily I got a AMD server in the workshop I don't need much speed for what I do and want one of them small EEE boxes!

 

[trog100]

that benchmark is how long a machine takes to calculate PI to one million decimal places.. your old dell would take roughly twenty five times as long to do it as my machine.. around four minutes..

its one of my hobbies i dont really need it.. the motherboard is running an fsb of 1800 mhz it should be 1333.. the dual core cpu is running at 4000 mhz it should be 3000.. for benchmark scores it runs at 1900 fsb and the cpu at 4500 mhz

i just like taking a cpu i pay intel 150 quid for and making it go faster than something they would have me pay a 1000 quid for if i was daft enough.. the machine has two high power 512 meg graphics cards and 4 gigs of system memory..

it all auto throttles down when browsing and such.. if it didnt my power bill would be thru the roof..

total overkill but it makes me feel nice.. he he

My hobby with PCs has turned into the complete opposite, I now seek out the smallest most power efficient and quiet machines I can find and experiment with operating systems to find the one that runs great on hardware like that. I have a small router sized computer called a LEX, it is a pathetic VIA Eden 466MHz fella but its fanless, it has a laptop hard drive but once booted from CF a very useable OS with web browser, music player etc, why didn't I keep it like that!? The damn people who built it put in the crappiest sounding soundcard I have everr heard!! Such a shame.

I used to be OTT with my machines aswell at one point I was messing around with evoparative cooling towers and thermoelec cooling so I could seriously overclock but the constant rain forest noise from the 6 foot cooling towers was enough to drive anyone mad LOL (not to mention the hum from the pond pump). Now I just have a fast slacer CPU overclocked with a Tuniq120 cooler in a sound prof aliminium case it's fast quiet and has enough kick to play with when im in a geeky mood(not so often nowerdays). It's funny everyone seems to want the fastest machine they can lay there hands on, I used to get people comming into my shop and asking me to build them the fastest machine I could for X amount of cash so there son/daughter can surf the web and do there homework, the reply was aslways do they realy need all that power when a budget pc will do all that just aswell?

 

[tribalmasters]

The supposedly big rigs we have in for repair always seem to have problems, the most common is the usual seized GPU fan and a dying hard drive, they akways feel flimsy if self builds and weigh nothing. I like the cheapo Dells that come in, they are heavy and are well built, they couldn't play big games but thats what games consoles are for!!!!

It was me that complained dude it just took for ever to charge had it on for 16 hours and it still only worked for 10 mins so got a refund of simon can't comment for the rest of his USB chargers but si did say he was having the same problem.

And the octopus picture of chargers was posted by EMP

Looks like this topic has kinda wondered off and is now buried/dead. I wanted to try and bump it to see if anybody thought this was possible/good idea? I found an article talking about a powered usb hub to charge up multiple USB charging devices (iPhone, iPod, etc.) and wanted to try it a few usb battery chargers.

What do you guys think? Too much? I want a way to charge a few batteries overnight without having a million of the standard "hardcore" chargers around (and why are the cords so short? ;-)) The USB chargers seem a lil more lightweight, especially with the rig in the picture running offa one plug. Was there any conclusion about how long the USB charger takes to fully charge a battery?

p.s. I'm Huey, been playin with e-cig's for a couple weeks now and been lurking around the forum for about a month but finally got an itch to register and post as I finally got a great e-cig and am ready to go mainstream and quit smoking!

You forget to take in to account the materials of the batt. the temp and such. if you take a 100mah batt. and hit it with 5 times the current the batt. you can melt overheat blow up or do a bunch of other stuff. You cant just assume more current means faster charg time, i.e. there is no way you could safely charg a baby e cig batt. from dead to charged in 30 min.

Didnt I read where someone Made a Usb feed for an E-cig?

Also, If your numbers are right, cant you just throw a 400Mah resistor inline to regulate the feed amperage?


*side note, I just built a new comp last year, my old one I called Baby, it was my first ever comp, It ran XP Pro, and it is a P2 (yes i said P2) 300 socket 1, with an old voodoo 7500, and 512 ram. I still use it as a back up
It was THE smallest comp to run the game Project Entropia, a MMORPG
A Microsoft tech once fell off his chair too, when i told him what was running Xp pro when i called with a Question
It ran almost any thing I could throw at it, there was only 2 games the frame rate would slow to nothing on. Thats when I built this, an AMD2 Athalon X2 3600 (will upgrade it when I can)

i didnt say it was wise i just said the usb socket has the power to do it.. and charging at 2 C (30 minutes) isnt wise but it is often done..

but a usb socket has the power to hit a 100 mah battery at 5 C.. the point of the thread being that some doubt a usb socket is up to the job..

they are more than up to the job.. the charger itself is what regulates the current.. three hours to fully charge a lithium battery is quite reasonable even thow some think it should be quicker..

100 mah is the normal output of an e cig charger.. as i said at the beginning of the thread 1/5 the (rated) output of a usb socket..

there is no doubt about this.. its fact..

ps.. powering an e cig is a different kettle of fish.. a usb socket isnt up to doing that job properly.. it exceeds its maximum rating..
