what is the max capacity it can read from USB?

Charlie, I use a uhs1 32gb SanDisk micro, which is about the limit for these single cpu cores. At best it acts as a backup disk, cache and you can push downloaded apps off to the external SD Chip to reduce the internal SD footprint.

I haven't used the USB but I have used a 16GB SD card with this. I usually just connect my Sandisk Sansa Clip Zip+ MP3 player to this and use it this way.

Great answers by some of the previous comments. There are no capacity limit on the source or destination usb pen drives. However, you will need to have the destination drive (the USB drive that needed to be copy to) to be equal or bigger than the source drive (the master drive that is reading from). Obviously, the bigger the size of the file need to be copy, the more time it takes to copy. No limit on the capacity, but the copied USB drive need to be the same size as the reader to ensure it can transfer properly without "not enough space" problems.

Not really. It reads usb drive. Maybe that's what's sort of smart about it.

Reads @ 19.5 Mb/s. Have not performed write test. Mostly use it for RasPi OS. Works well enough for that. Hope this helps.

It will read a flash drive as big as 8 GB. It will not read 16 or more disregarding the formatting of it.

It has to be at least USB 2.0. If the TD is formatted in FAT32 the max file size records for approx 50 minutes. It also supports an old IBM format, but you will need to do that format on a Unix based system.

Sorry...I have no idea. I've been using mine to read hard drives from old computers.

Max read range depends on numerous factors including the following:Size and shape of transceiving antennaSize and shape of transponding antennaPowerTechniqueThe maximum allowed for NFC applications is 10cm.I have not had very good luck with this reader or the company supporting it (tried to contact them many times, but never received any response).

No internal capacity. A USB drive can be attached directly or storage can be accessed via WiFi.

Do you mean the output voltage? If so, it outputs USB voltage (5 V DC at a max of 2 amps). If you're asking about the capacity, its 5,000 mah.

I really do not know as I have not tried using the USB ports, neither do I have the intention of using it any time soon. Sorry that I couldn't help with your question.

3GB is the maximum capacity that I've been able to bring mine upto. Excellent for Debian/Redhat/Ubuntu Linux distribution.

The maximum theoretical throughput of Tbolt is 10GBps. The overall speed of the reader depends on the device being read at USB3 or sata and that depends on the card.

The answer is not clear. I've read that it has a limit of about 70 pictures, so I bought a multi-GB USB stick that could hold hundreds of photos. At this stage I'm not sure if it is revolving all of the pictures that I have loaded on to it. There may be an internal memory limit that overrides the USB quantity.

No it can't. When connected to the USB, the device can't be used at all. It just mounts itself as a storage device.

Usb is 5Volts with .5A maximum draw. My multimeter won't even measure the current it's drawing so I'm not sure the exact wattage. So by using the above figures... 2.5 watts maximum although I guarantee it's definitely less than that. Hope that helps. The actual unit itself has no power listing so that's all I can figure for that.
