<div dir="ltr">Be aware that most tablets cannot provide much power over OTG. They can provide enough to power a USB drive, and some can power a mouse. But when I tried to power a atmega32u2 development board via OTG, it was very dependent on the tablet make/model as to whether it could manage. <div><br></div><div><a href="https://electronics.stackexchange.com/questions/181500/how-much-current-can-an-android-phones-usb-port-supply">Stackexchange</a> says:</div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">The OTG spec calls for at least 8mA and allows negotiation for higher currents if the peripheral needs more power. OTG devices can provide up to 500mA, but in realistic terms, handheld portable electronics don't have 500mA to spare for external loads. 100mA is a commonly accepted realistic maximum.</blockquote><div><br></div><div>So you may want to check with people who actually have the tablet you wish to buy. </div><div><br></div><div>G</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Aug 28, 2017 at 8:21 AM, Mark Atherton <span dir="ltr"><<a href="mailto:markaren1@xtra.co.nz" target="_blank">markaren1@xtra.co.nz</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi All,<br>
<br>
I have been looking around for a 10" tablet for a while and the Samsung SM-T560 is currently on sale.<br>
<br>
Unit has quad core 1.3Ghz CPU, 1.5GB RAM, 8GB internal FLASH, uSD card slot, but more to the point has WiFi and USB OTG - OTG being the deal-maker here. Also running Android 4.4 which is getting on a bit.<br>
<br>
Main interest is Web surfing, video playback, and control of some external home-cooked hardware via OTG (and associated 5V power).<br>
<br>
One test report claimed almost 9hrs of continuous video playback on a single charge which is quite respectable.<br>

<br>
Is anyone aware of a significantly better value-for-money product in the sub-$300 range (since I am picking it up, this includes GST, and $0 shipping).<br>
<br>
Thanks, Mark<br>
