Did 5V/2A 5V/3A makes a difference on a TV box?

[freakfly]

I've got my smart tv box running Amlogic s802 , and i am suffering from video stuttering, heard that 5V/3A power plug will make a difference as 5V/2a are more likely to cause playback problem. http://www.amazon.com/Tronfy-Andriod...rds=tronfy+mx2

I'm not so sure about a 3A ac adapter improving stutter perse.

I use one on my R28 and where it helps more is in providing more juice for external peripherals and in that respect there may be something in the playback ability.

Different box, different SoC, but prahjister says it fixed his problem.

I have been using the 5V 2A power adapter that was supplied with my MXIII for the past year or so with none of the video problems that you mention. I don't have any power hungry 2.5" hard drives connected to the unit. Some of these inexpensive power supplies can develop problems particularly if used at close to their maximum output power capacities. Any type of small irregular fluctuation of the power to the unit would be very difficult to identify without substantial effort. The easiest would be to try a different adapter to see if the problem persists or disappears.

Agreed. If you have no o'scope, substitution is the easiest way to check.
You may also want to try moving wireless dongles(if used) to a USB extension cable, but that maybe more of a Rockchip issue.

i have been using my mx3 for almost half year. with almost perfect till now..no suffering, maybe you need to clear data? i think

[freakfly]

ok, I tried another adapter first, it works fine on my Tronfy MX4 now, thanks.

@freakfly: Jean-Luc at cnx-software has investigated the power consumption of several of these android TV boxes. As you can see the power adapter needs to cope with sudden increases in demand. If you connect a 2.5" hard drive the power draw can spike much higher.

It did improve mine. I don't know if it was dirty or just not enough current. I don't have a tool to test.
