May 22 10:57:20 <Maxdamantus> Hmm .. yeah, this N810 lighter socket charger seems to be putting out voltages that seem very suspicious to me.
May 22 10:58:01 <Maxdamantus> When it's not plugged in, it puts out 11.65 V (input voltage is around 12.6 V, so it's not directly connected)
May 22 10:59:52 <KotCzarny> o.O
May 22 11:04:17 <Maxdamantus> 22:59:02 < Maxdamantus> it's Nokia-branded, and it says "5.7 V/890 mA"
May 22 11:04:19 <Maxdamantus> 22:59:53 < Maxdamantus> when I plug the N810 in, it drops to 3.something then goes up to 5.7 then after a couple of seconds the N810 says "Not charging" and it goes back up to 11.65 V.
May 22 11:04:23 <Maxdamantus> 23:01:37 < Maxdamantus> I remember when I was measuring the current draw yesterday, it wasn't drawing any current after that "Not charging" message, so presumably either the device is meant to handle that seemingly high voltage, or there's some overvoltage protection or something, dunno.
May 22 11:04:58 <KotCzarny> most likely

May 22 11:09:05 <KotCzarny> so that initial peak is for identification?
May 22 11:09:42 <KotCzarny> still, it shouldnt go over 9.xV
May 22 11:10:54 <KotCzarny> maybe you have some fake charger?
May 22 11:10:56 <Maxdamantus> Yep, seems to be all working if I just keep it around 5 V at the output.
May 22 11:11:02 <Maxdamantus> \o/
May 22 11:16:46 <Maxdamantus> Doesn't seem like it would be fake. I think it's just faulty.
May 22 11:17:01 <Maxdamantus> Wouldn't imagine someone would bother faking the Nokia brand on a charger.
May 22 11:17:23 <Maxdamantus> and it doesn't seem like a cheap PCB inside.
May 22 11:21:16 <Vajb> Typical behaviour in cheap non regulated chargers. Voltage settles to correct amount when sufficient load is connected

May 22 11:21:39 <Vajb> I've seen this in old car battery chargers at least
May 22 11:22:56 <Maxdamantus> I'm not particularly experienced with electronics, but I don't think that looks like some ripoff of a Nokia charger.
May 22 11:26:43 <Vajb> Me neither. Just some observation I've made
May 22 11:28:54 <KotCzarny> quick google says there are multiple 'dc-4' versions, lol
