| flowy | so i got an appropriate dc barrel <-> barrel cable and this external battery pack is working well... i think i should get at least 5 hours out of it. one question though: | 13:50 |
| flowy | the battery's output power can be configured between these options: 12v, 15v, 16.5v, 20v, all at 5a. is there any setting that would be optimal for the reform? or it just doesn't matter? | 13:51 |
| flowy | currently it seems to be working well at 20v | 13:52 |
| flowy | but 12v also worked | 13:52 |
| mntmn | flowy: the higher V the better | 14:09 |
| mntmn | flowy: so, 20V | 14:09 |
| flowy | ok great thx | 14:11 |
| flowy | at some point i think this battery + reform + solar panel is gonna come with me on a camping/cycling trip :) | 14:12 |
| mntmn | niceee | 14:15 |

| chartreuse | Higher voltage will mean less current for the same power too | 14:54 |
| mntmn | yep | 14:56 |
| flowy | i noticed on the battery's display a difference of around 2W when running the reform between 12v and 20v | 15:22 |
| flowy | roughly | 15:23 |
| mntmn | flowy: in which direction? | 15:25 |
| Boostisbetter | I have a 60 watt solar panel. Is that enough to charge the Reform? | 15:30 |
| Boostisbetter | I think it might only be able to do it at 9 or 5 V though | 15:30 |
| Boostisbetter | speaking of which are there any know cases where the LPC will glitch out? I had that happen yesterday and I had to unplug the batteries from the mainboard to reset it. Is there a way to reset the LPC without unplugging the power? | 15:31 |
| chartreuse | There's an LPC reset button on the motherboard. | 15:32 |
| chartreuse | Labelled LPCRST, just to the left of the battery connectors | 15:32 |
| sigrid | i notice a weird glitch where the batteries stop charging, with the red led flashing back and forth until i reconnect the power cord. then the led glows continuously and it's charging finw | 15:35 |
| sigrid | *fine | 15:35 |
| flowy | mntmn: idling, the reform is consuming ~12W (according to the external battery's display) when set to 20v and ~14W when set to 12v | 15:37 |
| flowy | they look so goddamn cute together with the matching OLED screens | 15:37 |
| flowy | mini displays i mean | 15:38 |
| flowy | Boostisbetter: how often does it actually output 60W? in my experience the reform uses more than 60W peak when charging @~19-20V | 15:40 |
| flowy | i still don't understand the basics of electricity so these things are just numbers to me :) | 15:42 |
| chartreuse | You don't need the full power to charge the reform, you can supply less than that and it'll just charge slower | 15:46 |
| chartreuse | Also that 12 vs 14 is probably just the efficiency of the boost converter at different input voltages | 15:47 |
| chartreuse | At 20V it's having to boost the input voltage less to charge the batteries | 15:47 |
| chartreuse | Which needs ~27-30v or so | 15:47 |
| chartreuse | I don't think I've ever seen 60W either. I typically see ~1.5A when charging and when near full charge at 26.7v that's around 40W | 15:49 |
| chartreuse | As long as you're supplying more than the ~7W or so the reform draws in normal use then it'll be charging. And if it's off basically any power will be enough | 15:52 |
| chartreuse | (Provided the charge controller can realize that it's not getting more) | 15:53 |

| Boostisbetter | That is really cool. It also seems like the circuitry is robust enough that MNT could make a power bank pretty easily if they wanted to. I personally think that would be a very good product and would love to buy at least 2 of them. Hahahaha. | 22:34 |
