ACASIS Acasis H027 Mobile Tablet PC Charging Cable OTG Micro USB HUB 3Ports Simultaneous Charging Power Transmisson Cable

This neat little USB hub has solved the obvious issue with the Microsoft Linx tablet which has no separate power port. It allows a mouse and keyboard to be used without being hobbled by the tablet's limited battery life and recharge rate. Tested with a mouse and mini USB hub/reader with an SD card inserted, the tablet still receives enough power to roughly maintain the battery charge, as it does when connected directly to a USB power supply. Switch positions 1 and 2 appear to work the same; position 3 allows the hub to operate from the tablet's own power so it can still be used when you don't have access to a mains outlet. It works well with my powered hard-drive docking station which has card readers and additional USB ports for more devices, such as optical drives, turning the tablet into a versatile mini workstation.

OTG/USB and charging works with Nexus 10 but not Nexus 7 (my N7 is very old and not updated so this might be a software issue). Functionality on Nexus 10 isn't absolutely 100%, the mode switch on the Acasis unit needs to be in position 1 when powering down or else the Nexus 10 appears to power down but is really stuck in a battery-consuming reboot loop. With the switch in position 1, the device powers down normally and charges as expected. The mode switch needs to be flipped to position 3 when the Nexus 10 is up and running in order for the OTG peripherals to work. My Nexus 10 charges successfully with the mode switch in position 1 or 3 but you need to develop the habit of switching to mode 1 before powering down. In my case, I can tell when I've forgotten to do this by the fact that my external USB mouse is still illuminated after (apparent) power-down. Just flick the mode switch to position 1 and power down the tablet again to get a proper shutdown. This Acasis unit also works as a host-powered USB hub (i.e. with no external power connected for device charging) but, if you have external power connected and then disconnect the power, I find that I need to unplug and then re-plug the Acasis unit into the Nexus 10 in order for it to switch to host-powered mode of the USB peripherals. I've tried a few other OTG charger units, only this and the "4 Port Micro USB OTG Charger HUB Cable For Tablet Phone" from banggood worked at all and they both work basically the same. Overally, highly recommended for Nexus 10 users.

I bought mine for a Viglen Connect 8" too but haven't managed to get it to be a USB hub and to charge simultaneously even having installed all the latest Windows 10 updates. It does, however, charge fully on setting 2 (turning the peripherals off) and access the USB peripherals (turning the charger off) on setting 3. At least I can switch easily between the two while working without having to unplug anything so not a complete waste. Can perhaps hope some future Windows update will enable it fully. It seems a well-made product, well packed. Arrived in good condition within 14 days.

Doesn't charge and allow data with my 7in windows 10 tablet, but as others state that seems to be a gamble depending on your version of Windows. Functions fine in every other way. Doesn't feel too durable but hasn't broken yet, and it's reducing wear on the device. Did however take several weeks to arrive.

Does not seem to work properly. quite a few devices plugged into it and not picked up my the tablet I use (Nvidia Shield K1)

too much chinesse on this... its not bad, It can perform what it says, however depends also on with devices are you using this... for me only the OGT worked with a HDD (no recharge avalaible meanwhile) but no mouse or keyboard worked with this on any way... also its hard to get recognized.

This has helped turn my Linx8 tablet into a mini desktop PC - it allows me to charge it while giving me 3 usb ports to plug in a wireless keyboard/mouse adapter, ethernet adapter and a USB key. The tablet loses charge very slowly under heavy load, but under most circumstances very little charge is lost during a full day and it usually maintains battery level (I have the original 2amp Linx charger plugged into it).

Got this plugged into my windows tablet running a USB flash drive, wireless mouse receiver and a wireless dongle. Does the job brilliantly. Very light and plastic wouldn't take much abuse but it's cheap and it's been doing it's job with no issues. I would buy this again.
