    Posted: 09 Jan 2018 at 10:49pm
anyone try to charge a Stratus while using the cable that charges the bluetooth keyboard?  I can plug my cable into the USB charger in the plane and it works fine but if I use the cable that charges the keyboard the charge light flashes red on the Stratus.

Flashing red on the Stratus means inadequate amperage.

If you want to charge two devices simultaneously, you need to get a better quality dual 2.4A usb charger, like the Anker units. About $10 on Amazon.

You can also use one of their power packs.

It could be that the cable conductors are not big enough to carry the current the Stratux needs to operate. The Stratux is a big power hog. It uses more power than an iPad and is very sensitive to any voltage drop caused by the slightly higher resistance of the skinnier cables.

I think that is what is going on.  You have to have a good quality wire and some amps to get it to charge.

It is very unlikely that the cable is much of the issue. Any USB A/micro power cord will carry at least 2A without trouble.

Clearly the USB unit can supply the Stratus, but not both simultaneously.

If it is a plug in charger, $10 upgrade to the Anker, and problem is solved.

No-  it won't charge (blinks red) whether the keyboard is plugged in or not. I have one of the hi-amp usb chargers installed in the plane.  Also I feel some heat where the connectors plug into the charger wire going to the Stratus.

So just plugging an unconnected second cable into the USB charger, causes the Stratus to blink red, but it charges fine when only it is plugged in? That is really odd. 

Perhaps the charger downrates one or both receptacles if it detects two USB A plugs?

Did you try swapping which USB slot the Stratus is plugged into?

Are you using the USB C charging cord that came with the Stratus? This is the Stratus2s?

Make sure it's not the cord receptacle on the Stratus - those are notorious for bad connections and failing. (I use my Garmin GDL39 3D over Bluetooth for Foreflight and I like it much better than the Stratus.)

Just to make sure I understand., you are plugging in just the Stratus. If you use the Stratus cable, the unit works, but if you use the keyboard cable, the Stratus doesn’t work. If so, it is likely the cable causing too much of a voltage drop. The keyboard cable is fairly thin.

Yes I think the keyboard cable is to thin.  I'm not using the black cable that came with the Stratus but it's a fairly expensive one and works fine unless the Avidyne charger cable is plugged in first.  Anyone else having this happen?

My Stratus 2 had some weird charging issues.  I opened it up and found one or two bad solder joints on the circuit board where the micro USB socket was attached.  I think I fixed it but haven't gone flying with it yet.  If the charging status changes when you wiggle the cable near the charging port, I reckon you have the same problem.
