YC-CDA19Q is an 8-Port Quick Charge 3.0 Capable USB Charger with a Display Showing Power Consumption

USB charger doctor is a cheap and easy way to monitor the voltage and current from a USB 2.0 port or charger, but you may have more than one device to monitor, and USB 3.0  type C ports as well as fast charger are now quite common, so it may not be suitable for all situations.

Bakeey YC-CDA19Q USB charger hub could be an interesting power monitoring device with 7 USB ports, including one supporting Quick Charge 3.0 fast charging, and an extra USB type C port.


  • 8x USB Ports
    • 7x USB type A ports including
      • 6x red USB 2.0 port up to 5V/2.4A each
      • 1x blue USB port supporting QC 3.0 (3.6-6.5V/3A, 6.5-9V/2A or 9-12V/1.5A)
    • 1 USB type C port up to 5V/3A
  • Max Power – 40 Watts (5V/8A)
  • Display – LCD display showing – real-time current and voltage, active charging ports, and charge status
  • Power Supply – 100-240V 50/60Hz power adapter
  • Dimensions – 138 x 75 x 50 mm
  • Certifications – FCC, CE, ROHS

What’s unclear is whether the display shows the output voltage and current per USB port, or the total from all USB ports connected. I’d assume the latter which may make it less useful.

The production description mentioned the gadget cones with a EU plug and a 1.5 meter power cable, but users report not getting a EU plug, so they had to use an adapter. I found it on Banggood for $24.99 including shipping, and while I could not find that exact model on other websites, YC-CDA19 model (not Q = no Quick Charge) is a little more common, and can be found on eBay, FastTech, and some other e-retailers.

  1. Six 12 Watt ports, one 18 Watt port, and a 15 Watt port–powered by a 40 Watt supply. *facepalm*

      1. Agreed. The display could use a button or two to select the channel to monitor, but the real flaw is the undersized power supply. It doesn’t have to be the whole (72+18+15) 105W, but half that would be nice. 60W is a common size, but 40W is just too low. That’s less than three ports!

        1. Depends if you’re powering devices or charging batteries. Li-ion charge cycles are broken down to 3 stages and it’s only during the first, shortest stage that maximum power is drawn: http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries

          So, since the 1st cycle is around a 1/5th of the 2nd and 3rd during a full charge cycle and much MUCH less during partial charge cycles, the PSU might actually be enough in most real world charging scenarios.

          But hey, your millage may vary 😉

  2. When are we going to see multiple type c connections on one charger? I’ve needed three at once for the last two years and still theres no sign of a desk, wall or power bank version.
