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.

Confirms this works with a Lenovo Tab3 7". The only product I've found that lets you connect USB OTG devices to, and charge an android tablet at the same time.

Fonctionne pour doubler un port micro Usb et fonctionne également pour mon usage, doit permettre la recharge en même temps que l'usage d'un port micro usb classique. Seul le modele qui fonctionne apres en avoir essayé 4 ou 5

Sono soddisfatto per l'acquisto.Ottimo prodotto ho risolto molti problemi per il collegamento del Hard Disk esterno sul tablet.Lo consiglio per il suo utilizzo

Ich war skeptisch ob das wirklich funktioniert, denn die Beschreibung ist etwas wirr und die Bedienungsanleitung sollte man nur lesen wenn man im Erdgeschoß wohnt, weil man garantiert nach den ersten Zeilen aus dem Fenster springt. Eigentlich geht es nur durch probieren und bestimnmt ist es auch abhängig von dem Gerät an das dieses Teil angeschlossen wird. Ich hab ein Huawei Mediapad T2 Pro und an dem funktioniert es wunderbar. Auf Stellung eins wird geladen und auf Stellung 2 kann ich das Zubehör das im Hub steckt betreiben. Stufe 3 scheint bei meinem Tablet dieselbe Funktion zu haben wie Stufe 2, ich benutze sie gar nicht. Wenn ich von Stufe 1 auf Stufe 2 wechsle, wird das Gerät weitergeladen oder zumindest nicht entladen, immer unter der Prämisse daß ein Netzteil angeschlossen ist. Das Laden erfolgt langsam, was mich aber nicht stört. Kurzum, es macht genau das was es soll.

This is a great little device, and for what it does, is an excellent value. I searched high and low for something that does what this does, until I finally found this one. Of course, that was when i started seeing a few more pop up. : - ) THERE IS ONE THING....it doesn't give enough of a charge to go a very long time while your device is running hard; for example, when I only used it for a couple hours with a flash drive usb, wireless usb mouse, usb-powered external speakers, and Bluetooth running my wireless keyboard, it worked great, and seemed like it was charging. I write that it "seemed" like it was charging, because it does not SHOW that it is losing charge, i.e. if the taskbar shows the battery at 100%, that's where it stays....no matter what. Doing the same setup while connected to a Microsoft wireless adapter (minus the external usb speakers playing sound) streaming the tablet to the t.v., without warning, while still showing 100% on the taskbar, the battery drains straight down to zero, and shuts the tablet off until it is recharged again. 2 notes of mention: 1.) Put on battery-saving mode, as I am guessing this may give the warning that is necessary. I had mine turned off. This happened to me a few times, so it is not an issue of not connecting it right with a hard reset after rebooting (this must ALWAYS be done for the charge function to work). 2.) Make sure you are using at least a 2.0 amp output charger connected to the Acasis otg/charging hub. Basicaly, while acting as a pass-through, the otg/charging hub slows down the rate of charge necessary to keep up with long use, especially while doing something that is draining a lot of juice, such as streaming while utilizing otg and Bluetooth devices. Again, all-in-all, it works great for a couple hours if you have a wireless setup like I first mentioned above, and are doing browsing, or even watching or listening to something from the usb flash drive. If you are only using the hub to charge, it takes several hours (probably twice the time as with regular charging) to go from low battery to full. Remember to always do a hard reset (pressing power button to shutdown) after any reboot and/or update that takes place on the tablet. If you're in a hurry to charge your tablet, unplug the Acasis hub, and use your regular charger. NOTE: while this works with my HP Stream 8 Windows tablet, as I wrote about above, it does not even slightly work with my Samsung Note 4 android phone. I believe the phone may not have the capability to charge and do otg at the same time. The seller does make mention to research this for your device before purchase.
