USB Pwr/AV port problems

13 comments

For the last year I had the power supplied via the USB cable in the USB/AV as stated in the manual. Recently I noticed the K1 wasn't working right. It would start and stop recording over and over. When troubleshooting I noticed that once I plugged in the power the screen died and the problem appeared. If I tested the unit with only battery power it worked fine until the usb power was applied. Today I decided to try and plug the USB power into the USB port used to connect to a pC and it works fine. Is this normal or has anyone else have the same issue.

 

Thanks

The K1 needs 5V 2A power supply to work properly, and the most USB port may not supply less than 2A and will cause the issue you mentioned.

 

There is supplied converter in the package, you can connect the converter to battery from bike directly and DVR, that can get enough power supply and check if it can work properly.

As previously mentioned, I have been using this init for over a year and have the provided power supply wired directly to the battery. Can you tell me why everything works as normal when the same USB is connected to the other USB port? Thanks

Let me clarify,

 

For last year, you always used USB cable to connect the USB/AV port, the port #4 and the USB Port from bike to power up camera system, and it worked well without issue till now.

 

Is that correct?

 

Have you tried to wire DC converter to battery from bike and power up the camera system?

Yes, I had the USB power to port 4 as described in the manual and it works fine. I have the DC converter connected to a Power management fuse block and the K1 is wired to a switches circuit.

Today I decided to try and plug the USB power into the USB port used to connect to a pC and it works fine.

 

Base on above message and your last post, if the power supply from your bike get problem?

I think you are following me at all. Port 4 (USB pwr/AV)on the left side of the K1 does not work on the bike or connected to the PC. If I use the PB USB Port on the right side of the unit it appears to work fine. The bike power and USB DC Converter test just fine. Something is wrong with the K1. My question is and I cannot seem to get an answer is why would the PC USB port on the right work but the USB pwr/A port on the right not?

That is clear now!

The port #4 was always connected and there were sharking between the USB plug and DVR, that might damaged port by timing.

The port on memory side has not been used, so it is OK.

Port 4 still appears to be getting power but the screen immediately blacks out. I guess it could be a bad port but have an issue if it is damaged from any potential shaking. I have this thing tied down pretty good and have never experienced any other USB device on any of my bike ever having this sort of issue. It concerns me that after spending this kind of money after another year I may have issues using the other USB port. This device is designed to be used on a motorcycle so there is always going to be some shaking.

Hi Rich and Innovv Team!

I have exactly the same issue! Today I connected my DVR directly to the USB charger with 2A output (Oxford) via Pwr/AV socket and display works fine! Where is the problem?

Did we installed the cable connection clip to fix the connection between cables and DVR as below,

 

The cable connection clip is designed to fix the connection.

Some of us purchased the K1 before you started including this cable clip. I don't recall you ever offering it to previous buyers even though you realized that there was an issue.

Hi Rich, just sent email to support@innovv.com, and let us know your need and shipping address, we will arrange one set to you free.

Thank you but that won't be necessary. I was just pointing out that not all of received the cable clip that was added later. I have my system pretty secure and have not had a problem until the recent power issue. If and when I need to replace my current K1 with a new one I will make sure I have the additional cable clip. I'd like to see a new model some day with a larger display and maybe some sort of single cable adapter. I'd like a display (maybe 4 or 5 inch screen) that can be mounted in front of me so I can leave it on the rear camera view but have all but one cable hidden from view. Thanks, Rich

  • After receiving all possible failures from this product, a logical question arose. - So how to buy spare parts for INNOVV K1 from you (manufacturer)? After buying the battery, it turned out that one of the cameras (rear, but installed in front due to the length of the wire) also came out of standing. - How and how much does your new camera cost instead of a defective one? - Where, how and at what price to buy safety glasses for cameras? - Where, how and at what price to buy a new power supply for the camera, because the old power supply does not hold stable voltage and current, as well as poor contact at the USB A female connector due to flat tracks? Remind everyone that You can buy battery pack from GoPro for: HD Helmet Hero, HD Hero, HD Hero 2, HD Hero 960, HD Hero Naked, HD Motorsports Hero, HD Surf Hero part numbers are: ABPAK-001, AHDBT-001, AHDBT-002
  • Hi Rock , as per my post in the K2 forum, the K1 has been brilliant up to now, but following that post, I think I spoke to soon !! last night I went to download the footage but the unit is completely dead, won't turn on , nothing, the charging light on the side is on (faint white light) but nothing happening. I tried a reset, plugged it back into the bike, nothing, completely dead, any ideas what is wrong? thanks
  • So I noticed that in most cases with me the Recording stopped failure happens when I have a drop in batter voltage. Was thinking. What if an inline batter was put in place between the power source and the DVR. Think on of the USB battery packs. Now you would need one that started charging and recharging automatically but think this could solver the problem. The battery pack would simply act as a UPS. Something the onboard battery should already be doing. Also has anyone else though of installing a heat sink on the DVR or even the battery?
