Hi everyone! I know that I can check the battery level by pressing the HELP button, but this only works when the OP-1 is turned on, not while it’s charging. When I charge the OP-1, the battery LEDs all light up one after another, even if I’ve just started charging, and it was empty. It always goes through all 5 LEDs, including the red one. How do I know when I can disconnect the cable?
When it’s charging the LEDs light up one after another.
When the OP-1 is fully charged while turned off the lights stops blinking
Thanks, I appreciate the info! I’m a bit worried because the OP-1 has been charging for more than 11 hours now, using this USB hub. It’s connected to one of the PowerIQ ports (they are dedicated for faster charging).
If the OP-1 works otherwise, then I wouldn’t worry too much. Let’s just say its OP1nion of the state of its own battery leaves a lot to be desired. Always has been this way.
My OP-1 can take 6-7 hours to charge when I use a mac. I usually charge the device when it still has some power left in it, so if your OP-1 is completely empty 11 hours sounds about right I think…
Charging with apple charger directly from the wall is supposed to be quicker I think
Thanks for all the input With the apple charger directly from the wall, I’ve managed to get it fully charged (i.e. all LEDs light up when I press HELP).
I usually do 4-5 hours from an old mac book, with op-1 switched on.found the meter too unpredictable when switched off.
Late reply, but wanted to mention that I had the same issue with mine - I let it charge overnight and battery meter still reported only half full. I’m pretty sure it needs to be calibrated by letting run ALL the way out of power while using it, then give it a full, uninterrupted charge. Problem is, I have been playing on this little guy off and on for two weeks and the battery just won’t die! The battery meter may be finicky, but this is a hell of a battery! I’m sitting here now just letting it loop on a track, still waiting on it to go dark!
Okay, so yesterday I tested how long it actually takes to charge it from 0% to full (so the LEDs stop flashing). I started at 7am yesterday. Today at around 11am it was done. So my unit takes around 28 hours for a full charge. I used an Apple USB-Wall adapter, and the USB cable that came with the OP-1.

I used an Apple USB-Wall adapter, and the USB cable that came with the OP-1.I ran my OP1 flat the second day I had it (didn't charge it out of the box), and then charged it to full. I was less than 6hrs to charge from completely flat to full.
I should do a bit more research on this (but I’m lazy ;). So far I don’t think it’s the charger making the difference. The OP-1 itself limits the charging current. The quality and length of cabling can have some influence though.
@MirEko That’s interesting, thanks for the input. May I ask, when did you buy your OP-1? Maybe the charge speed has changed between “generations” of OP-1 productions…

Only a week or so ago
Same here. MirEko and myself bought our OP-1’s around the same time. Afaik they haven’t changed the charging circuitry between hardware versions. I’m going to cook up something that can log the charging current and voltage during the whole charging cycle. When I have some time to spare.
