Windows tablet power from USB?

Recommended Posts

Unfortunately I haven't had the chance to test the ecu connectivity / charging yet as my right angle cables and OTG hub haven't come in. Will be sure to update you all though.

Will the ECU USB output enough ampage to charge the tablet while in use?

A standard USB 2 port outputs 500ma and a USB 3 outputs 900ma, I would imagine the tablet to need about 1.2amps+ in order to charge it while the screen is on or the tablet is being used

The ECU is not a charger (or a USB host), it is a usb "device" just like a USB mouse or flash drive - do either of those charge your tablet when you plug them in?

Bought one of the Noel Leeming tablets, on special for NZ$199 until Tuesday.  Haven't had a chance to play with it much yet, but looks pretty good, and that price is hard to beat.  Will need to find a 12v to 5v converter to plug in to the DC power.  Not sure how I'm going to mount it yet.

Tablet from Noel Leemings works brilliantly and having 2 USB ports made it so much easier designing my dash layout with a full size keyboard and mouse connected, plus being charged via the DC Port.

looking good Greg. wish I bit the bullet and got one of those from NL when on sale last weekend!

can you alter the VE tables? and also activate / deactivate quick tune using just the touchscreen? how do you input numbers? or is that keyboard requirement?

thanks
marc

I'm a complete novice, so learning as I go.  Its the full version of PC link, so you can do everything.  The tablet though is too slow for doing anything much more than displaying the dash.  I'd want a keyboard and mouse if I was to even try to use it for anything more than a dash.  I was thinking of getting a bluetooth keyboard etc to use with it, but don't see the point.  If you want to tune, a laptop has the power to do the job properly.

If someone is still looking for a Windows Tablet that has confirmed OTG working:

I'm using a Jumper EZpad mini 4, which is working pretty good in my R34 GTT since last summer.

Mounted it on my dashboard above the climate control using neodym magnets (https://en.wikipedia.org/wiki/Neodymium_magnet) that are installed behind the dash plastic and hook onto metal plates glued to the tablet.

So you can easily remove the tablet without the dash looking like crap :)

Charging at full display brightness is limited, but the battery is big enough that you can do 4+ hour drives without problems.

The tablet is fast enough to be used as a display and for limited additional functionality (like turn on logging etc.), but for proper tuning it is sadly too slow.

Not power related, but last night, I took control of my home computers (desktop and laptop) from my in car computer, via wifi hotspot on my fone.

And vice versa. Was testing to see if I had to use my laptop plugged straight into the ECU (or if I could just use my PIPO) to remote tune.

Haven't road tested, but looks promising.
