Hidizs DH1000 using a USB Meter to simulate a Y cable

Hidizs DH1000 using a USB Meter to simulate a Y cable

Hi everyone,

As you may have seen from my previous posts, I’ve been developing GUI’s for FLAC and Opus, which are 2 great audio formats. This, of course, means I listen to music, and to enjoy them, I use my Hidizs DH1000 USB DAC/Amp. The sound it produces is awesome, but I’ve been having issues lately due to it charging very slow.

Because the unit charges very slow, at just 0.09A according to my meter, I needed to figure out a way I can keep using my DH1000 without sending the unit back to China for replacement. Of course, this is easy, because the unit features 2 USB, you can just connect 2 MicroUSB cables and have the problem solved. This would send power to the unit while you enjoy music, but what if you only have one USB socket available? Yes, you can use a USB hub, but I don’t think it’s recommended to use one because it would have a Hub in the middle and not a direct connection to the DAC, and also you’ll have several cables around.

To do a simple test, I purchased the PortaPow USB Meter which features 2 USB-A ports. One is for charging only and the other allows data transfer and charge, so the connection I’m using is the data port to the DH1000 data port and the No Data + SmartCharge port to the DH1000 microUSB charge port:

With the meter, I could see that the unit is working and it is also drawing power from the USB port, which is what I initially wanted.

I also tested this with my Hiby R3 as you can see below:

The Voltage seems to be below 5V, but it’s working fine. The downside is that the R3 battery drains faster, but for short-term music listening, this is fine.

My next step is to find a good USB-A to Micro USB Y Cable that provides charging and data to keep using my DH1000 for as long as possible.

I hope you enjoyed this post and found it useful. I know there’s some of you that have the DH1000 Blue Light issue, and that’s why I also have the rubber band that came with my unit in the DH1000, because I also have that issue. But hey, at least the DH1000 is still working great!

See ya in my next post!

The PortaPow Data Blocker USB Adapter with Smart Charge

The PortaPow Data Blocker USB Adapter with Smart Charge

Hi everyone,

Today, I’ll show you the PortaPow Data Blocker USB Adapter with Smart Charge.

This is an adapter that, as the title says, blocks Data. This means that when you use this adapter in a PC USB Port, it will allow your tablet/phone to charge at the port maximum speed, overriding the 500mA USB limit. This is because when a PC detects a data connection, it negotiates the power with the controller. Some devices uses 100mA, like mouses and keyboards, and other more powerful stuff uses the full 500mA from the port. However, since this adapter blocks data between the device and the PC USB port, it doesn’t negotiates the power needed and as such, passes the full power the USB controller can supply.

The SmartCharge meaning in this device is because there is a controller that can check what device you have connected. There’s several charging standards like Samsung, Apple, and others. The adapter will detect that and because of this, allows fast charging for your device.

Please bear in mind that you must use a high quality USB cable or your device may not charge at full speed.

Let’s take a look at the adapter:

I purchased the 2-pack PortaPow Data Blocker on Amazon, so that’s why you see 2 adapters there.

Taking off the package contents, we can see again the 2 adapters plus a product overview sheet:

That sheet also has some important information, like that you need to use a high quality USB cable and that the USB port must be able to supply enough power, or your device may not charge at fast speeds:

Testing the adapter:

For this test, I’m using an Aukey Micro USB cable, which is of good quality. I’m also using my Lenovo laptop USB 3.0 port. The app being used in the phone is the Pro version of Galaxy Charging Current, which is an excellent app to measure how much power our device is consuming from the USB charger.

Here, I’m charging my Samsung phone by directly connecting it to the PC USB port. You can see that the power being drawn is 433mA because the PC detects there’s data and negotiates the power to 500mA:

However, when I plug the PortaPow Data Blocker, we can see it charges normally at 1200mA, or 1.2A. This is normal for this device when not using Qualcomm Quick Charge. The device is charging at 5V here:

See the difference between using the adapter and without it? Now our device charges faster and comes in handy when we can’t use our wall USB charger.

That’s it!

I definitely recommend this adapter. It is cheap too! The 2-pack costs only $12.99 on Amazon.
