http://www.oppoforums.com/threads/tips-tricks-for-vooc-rapid-charge-why-doesn%E2%80%99t-my-phone-vooc.17595/
I just received my HA-2 today primarily for use with my LG G2. The 2 devices are exactly the same size and the LG usb output works perfectly with the HA-2.
Prior to ordering, I called Oppo customer service and asked if the HA-2 would also work with my Google Chromebook and my Xubuntu 14.04 Linux computer via the usb outputs of each. They said neither would work with the HA-2.
Despite this rather discouraging information, I decided to give it a try with both my Chromebook and Linux OS computer. Both worked perfectly! I am pleased that I now have a multi-purpose device that I can use with all of my primary music sources. Unfortunately, it is not recognized by my DX-90 although I can use it via line-out to line-in. I haven't done enough testing to tell whether the HA-2 amp is an improvement over the DX-90 internal amp. Time will tell.
Bottom line is: Don't be discouraged by Oppo's rather negative answers to technical inquiries as their replies to my inquiries were incorrect.
Why don't you just use the stock charger?
I have different chargers at home and at work. I also don't want to leave the 5A charger at home because I'm afraid someone at my house might use it for a device that doesn't support 5A on accident not knowing. So rather leave 5A charger in my office.

The 'smart' part about modern USB charging method is that the device only draws as much current as it needs where the charger only supplies as much current as the device is asking for, or until it reaches its maximum output power. Saying it is capable of 5A doesn't actually mean it is outputting 5A blindly all the time. It is much more clever than that, and more so with Oppo's VOOC.

You can take a 50 amp 5 volt supply and connect a device that only will "draw" 1 amp at 5 volts and cause no harm. Keep that term "draw" in mind. Another good term is "pull"... the supply will not give a device any more current than it "pulls".
Voltage is different. Being the drive or push or pressure part of the equation, if you go over the device rating, it can cause damage.
If you read the linked piece by Oppo, beyond the above rules of electricity, the VooC charger requires intelligence on both sides, the device and charger to ever get to fast charge mode. It also requires the provided 7 pin USB cable. Otherwise it will perform like any other 2.1 amp charger.
You have nothing to worry about!
Thanks, I thought the Cell phone oppo was a different company. Yet they have the same charger?
Thanks, Yeah I get it now. Like plugging in a smaller 110v 1A device into a 20A outlet vs a 15A outlet won't harm it.

yes, they are different companies with different headquarters, different management, and different staff.

Well feel free to correct me if I am mistaken, but I am pretty sure that OPPO is just a brand name. parent company is bbk electronics. BBK Electronics to Oppo Digital and Oppo Electronics is similar to Luxottica to Ray Ban and Oakley.
You can't buy or get support on Wayfarers from Oakley, just like you can't buy/get support on the HA-2 from Oppo Electronics. From the consumer experience, basically unrelated companies. They just share a common umbrella company has a controlling interest in both subsidiaries. The subsidiary companies do operate independently. Oppo Electronics & Oppo Digital have separate stocks.
Maybe Walt Disney Corp holding ESPN and Disney Channel might be a better analogy as the Disney brand name is shared between the parent and subsidiary. Oppo Digital is licensed to be able to use the Oppo brand name.
