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.
Specifications:
- 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
- 7x USB type A ports including
- 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.
