There is a reason that HDTVs USB were never designed for a Fire TV or other streaming devices. The engineer selecting the USB chip can choose a current limit or voltage limit.

I’ve been using this for about 6 months now and I absolutely love it!! I am not super tech savvy so this is so nice to be able to just plug in and it works like it’s supposed to. The USB port on a TV could be designed to provide up to about 2A of power, this isn’t an issue, but it does take more components and increases cost. The port can also be designed to always provide power, regardless if the TV itself on. It’s just a design decision, which has to be balance against other concerns like phantom energy usage. I’m looking for a USB-OTG Split cable that would also do Power Delivery but is quite hard to know if the cable would actually meet the requirements as there are a few around that have comments complaining that they throttle the power delivery and their devices (like tablets) don’t charge properly. Say Goodbye to Messy: Remove clutter from behind your TV by removing the long USB cables that can hang out from behind your TV.

It’s more likely a misbehaving application that you have installed, or it could be a networking issue. A. No, the cable is designed to always have sufficient power, even after many hours of continuous use.

Short answer is no, you won’t know unless you use test equipment, other than see flaky behavior. I have suitable equipment for testing USB voltage and current, but going into details is beyond the scope of of this thread. Compatible with most devices with micro-USB connectors (smartphones, tablets, E-readers, games consoles and more)Without going in the details of how a switching power supply works, voltage drop for various gauged cable over a given distance and current, etc. Just know this: Boats by their very nature require improvising and out of the box thinking, and in this case it doesn’t require much. The picture quality and sound quality are perfect there’s no distortion and if the video watched can handle it, it can easily manage HD quality.

Each of these things can be determined through the process of elimination. First the power: Try using the device with a good quality power adapter with plenty of current (1.5A or more) and a short high quality cable and see if the issue goes away. The streaming speed and quality are exceptional. No more endless buffering or lagging—watching content is smooth and uninterrupted, even in high definition. Ron: Indeed, sometimes outlet location can be problematic. My bedroom TV is just barely too far from the wall outlet to plug it directly in, so after consulting Zeric on this very forum, I learned I could use a good quality extension cord to make up the shortage. It works just great! I never even tried using the USB on the TV – especially after reading all of the quirky results contained herein. Also, a good quality power strip will function in the same way if you are able to plug it in. If not, your motor home situation, I would guess, makes your current set-up inevitable unless moving the TV is practical. My guess is it isn’t. Best wishes Michael is not quite correct in his explanation USB and power design considerations, an area I have some expertise in as an EE.Mission USB Power Cable includes special power management circuitry that enhances the peak power capability of the USB port by storing excess energy and then releasing it as needed. All the information is based on the technical FACTS instead of uneducated, best guesses based on any personal preferences or limited experience.
