The main reason why it got a suspect by the customs: they included a american power cord in the package! Holy moly what would've happend if the user used that cable? USA(120volt)(germany 230volt)

That guy would be burned by now.

last i checked, the North American 115V plug is a lot different then a EU 230V plug, so I don't think there will be any issues with it setting the place on fire.

however, the power adapter might not handle 230V, even with the right cord type. A new one may be needed (not expensive, but still a PITA

as far as i know, they don't need to send Plug's with it, because someone on BFL s Forum used a self built
6 PCI-E Power Cable
it's just a stupid Joke or the Customs Officer has gone full Retard.

My Jalapenos made it through Australia Customs without hassles. I've had other gear delivered from the USA, Europe and China with their plugs and no one cared.

When I first heard of the 'CE' China Export tag a few days ago I thought it was a silly online joke. It staggers me that someone in China thought this was a great idea. Total coincidence that the two logos look virtually identical Roll Eyes

I have purchased a Dell laptop PSU online that turned out to be fake. It had a couple of spelling errors on the label and got quite hot in use. I'm not surprised Customs may be picky about laptop PSUs as it's a real safety issue.

No 'UL' mark on my Jalapeno PSUs, and of course no markings apart from a serial number on the actual Jalapenos.

The crazy thing is, if they ship the Jalapeno separate from a power supply, they don't need certification, as they are not a mains powered device, if they bundle them together then they do as it's considered part of a system.

I guess if BLF were smart they could put them as separate items on the paperwork so they are not a system.

Obviously you are not a teacher by trade by assuming people "switch" off? Tsk tsk.

Good heavens no! I'd be prone to throwing students out windows from frustration... I have all the patience in the world for those who want to learn, but anyone who wastes my time... Well...

Looking at the BFL supplied cable, its rated at either 3A or 8A. Not huge wattage, but more than enough for a Jalapeno.

Is rated 6 A.

So it is... So theoretical maximum of 1500w. For sure I would not be comfortable running that much power through it (it would get warm) but still, more than enough to manage.

13v x 6A = 78watts max.

Cable != power supply. The supply is rated at what, 78 watts, but the actual cable from mains to the power supply is rated to a maximum of 1500w. As said though, I would not want to try putting that much through it as it would certainly get warm.

Would it get warmer at US voltage (110) or UK voltage (220) if you put the maximum 6A through it?

It would get just as warm if it was 6A on either voltage. The resistance would be the same, so the energy lost in the form of heat would be the same. Proportionally you would be losing more at 110v though. Where it gets fun is when you're considering watts (I*V=W). If you're using 220v you only need half as much current as if you're using 110v to get the same number of watts, and because resistance in wire results in a voltage drop you'll find greater heat resulting from the lower voltage at higher current than you will find at a high voltage, low current system.

I haven't really explained it that well, but a quick peek on wikipedia should fill you in on the details Tongue

I was actually just making sure that you were at least remotely qualified to be giving people advise on things electrical. I'm an EE. Heat in a cable is I^2*R - voltage has nothing to do with it.. (well, alright, not NOTHING, but very very very little)

Good answer.

Enigma.

Been a long time since I've had to use that set of equations seriously... Last time was building heater cores out of nichrome wire and furnace cement. You're right when it comes to heat being directly connected to current and resistance, the voltage only becomes really important when showing the difference in current between a ~220v and 110v system.
I'll admit I did deliberately simplify and use DC characteristics rather than getting into the fun of AC and varying currents over small time periods, not to mention the wonders of inductive loss (or melted PSU cables from idiots who like coiling them into tight bundles!). Few would recognise the difference and would just go "Oh, MATHS!" and switch their brains off Tongue

The resistance of copper wire goes up with temperature. 4.9 x 10^-3 is the coefficient.

If you think you are going to have customs problems, ask for the miner to be shipped without a power supply and source an approved one locally yourself. This is what Avalon have been doing, and probably why KNCminer are going to ship without a power supply.

The alternative is the possibility of not having your ASIC miner.

I can imagine the answer from BFL:

Quote

All sales or final, we can't do it.

They have already been shipping Singles without power supplies for some people, this is obviously a potential problem, and it would be nice if you helped people with useful suggestions or refrain from posting.

It would be nice if you followed your own advice instead of being a BFL spokespuppet all the time. How about next time you see Josh in the office you mention to him he might want to follow the law instead of dumping mistakes like this in his customers lap.

You make it sound like it was an aborted baby.

That would be an insult to aborted babies everywhere. Cheesy

Even in non-EU states(like Switzerland)!

Never had troubles with Swiss customs. And as a HAM I shouldn't have problems to import hardware without CE sign.

I guess only iANDROID had problems (are you from Germany, living in FR ?) Grin
