The problem with this is that it is USB 3.1, I think the adapters that OnePlus uses in USB 2 and that is why only their adapter works. for OTG

Isn't USB 3.1 supposed to be backward compatible or something?
I got a USB Type C to USB 3.1 Type A female adapter for OTG with my OP2 but it isn't working...

[Beware] Anker chargers poor performance

We have tested Anker 60W 6-port and PowerPort4, they couldn't recharged all Xiaomi genuine power banks at 2A. (Max @1.6A)
And sadly, it only could recharged at 0.9A with Asus Zenpower power bank.
Please see the following links :
Testing PowerPort 4 with Asus Zenpower 10050mAh :

Beware if you would like to purchase Anker chargers to recharged non-Anker power banks with 2A Input spec.

Excellent QC 3.0 Car Charger

Just to share an excellent QC 3.0 car charger. I bought it along with the Axon 7. It is fast, even when using an old micro-USB cable+adapter, and it doesn't heat up even after more than 30 mins of charge. It also has another USB port for standard 5V USB allowing up to 3.1 amps at the same time through the second USB socket. It is also inexpensive and fits perfectly into the 12V car socket, with that I mean that It doesn't come out with vibrations. So no no-battery surprises when using navigation software. In my case the blue light ring fits perfectly to the color of the rest of the dashboard lights. And it is also very small.

I am quite happy with it and I wanted to share this very positive experience with the community.

UK P2 fast charger

Hi,
I purchased the Lenovo P2 4/64GB (P2C72) from Gearbest as Three UK doesn't stock it anymore and it came with a 2 pin fast charger and I don't like to charge the phone with a power converter adapter so currently I'm using a 5V 2.4A charger but the specs seems to be lower than the P2 fast charger so I'm wondering which charger I can buy on Amazon UK that is the same specs as the original fast charger?

Short version seems to be that you can't get one. It's a proprietary fast charger. I just use an adapter and the stock charger when I want to fast charge it. It's worth it as it is extremely fast, by all accounts faster than qc3.0.

Spectra USB DAC

I have this Honor 7x, it's the first phone I haven't rooted or changed the Rom. I'm quite happy with it.

I like to listen to music and I have the Spectra USB DAC. It doesn't work on the Honor 7x. On my previous Note 3 (R.I.P) I had a micro USB 3 Adapter that worked.
For some reason the Spectra doesn't work with a micro USB to USB-A host Adapter. I have also tried using a micro USB cable and then plugging in the Spectra through a USB-A to USB-A Adapter.
Still nothing. I wonder if it is a hardware issue or something is missing or disabled in software?
