Question: Is this will connect to galaxi tab 2
Document: This is EXACTLY what I needed to connect my Duracell portable power pack to my Samsung Galaxy 2 Tablet. I ordered numerous things, and this item arrived before items that were ordered within the US! Very happy, highly recommend this seller!
This way I only have to travel with one cord and an adapter. Fits much more securely than the Samsung OEM cable that comes with the Galaxy Tab 2.
Will not work in Galaxy Tab 2 10.1. The tablet will not charge. Tried several different chargers. It just shows an X over the battery indicator when this is plugged in.
I can charge my galaxy tab 2 10.1 with this adaptor using USB connected to my PC. But the charging speed is quite slow. I will use it for emergency.
With the reasonable price on this adapter, it works as expected with no issue. I use it to charge my Galaxy Tab 2 7 inch with no problem. The built quality is good enough for the cost. So it is very useful and valuable add-on for my tablet.
Ordered two (style shipped in November and looks different them shown above). Like a fool did not test them right away. Took Samsung Tab 2 10.1 on trip with new connectors only to discover neither would work with my Tab. Tried several different chargers and usb cables, none worked with either. Result dead Tab while on trip with my travel info inside. No Maps, Tripadvisor etc, very upset both with myself for not testing at home and with Portapow for very sorry product.
This is what it says it is - it's small, it lets you plug in a USB Micro cable to charge. For me, I'll be keeping it in my travel bag. I don't know about using this every day because it is a little bit bigger than I'd like and depending on the cable you plug in to it, it can make the connection ridged. I plugged mine into my Galaxy Tab 2 10.1 and if I moved the tablet around on the table I could hear it disconnect and reconnect (but stayed connected if I left it alone).Good to have this in your arsenal but if you have spare charging cables for your device I'd rather use those.
It works fine for charging, but I could not get it to connect to a PC even though I tried several cables and a couple of laptops
I bought this to use with me galaxy tab 7.7 so far it does what it is advertised. Great price
easy to use and much faster than the cable received with the Tab - one two three four five six
Answer: I'm using it on my Galaxy Tab 2 and it works fine :)
