2A Dual port XHC10
I got it from Ebay dealer: china-town-us and selected model for "HTC One M9/M8/M7/Mini/X/V/XL/S/Max"
- Protective circuit to prevent overcharging.
- Use your existing USB charge/ sync cable for charging.
- Pocket size, Compact, lightweight, durable, easy to take anywhere.
- Plug Type: EU Plug/US Plug
- Output: 100-240V 50-60HZ
- Output: 5V-2A
- Power consumption when idle is 0.1 watt
- Ipad usb output is coded as Apple 1A
- Galaxy output is coded as Samsung
- All outputs are in parallel.
Each output can deliver exactly 1.5A before the overload protection trips.
And because they are in parallel the total output is also 1.5A, not the rated 2A.
I could draw 1.5A for 1 hour without any problems.
The temperature photos below are taken between 30 minutes and 60 minutes into the one hour test.
M1: 44,2°C, HS1: 56,2°C
HS1 is the rectifier diode.
M1: 50,3°C, HS1: 70,2°C
M1: 61,8°C, M2: 65,0°C, HS1: 74,9°C
M1 is the rectifier diode.
M1: 46,3°C, M2: 55,3°C, HS1: 58,8°C
M1: 49,0°C, HS1: 60,8°C
Noise at 0.5A load is 134mV rms and 1250mVpp
Noise at 1A load is 87mV rms and 1080mVpp
Using my vice I could pop it open, but the plastic broke in the seam.
On this side there is a fuse, a blue 1000 volt capacitor that will short on high voltage (Very bad). There is also a rectifier diode.
Here the fuse, the blue capacitor and the rectifier diode can be seen. A close look on the capacitor will show the 1KV marking.
On this side a bridge rectifier and a switcher IC can be seen.
The isolation distance is 4mm, this is below requirements, but not directly dangerous. The dangerous part is the blue capacitor.
The charger passed an isolation test with 2500 volt, but failed a 5000 volt test and shorted between low volt side and mains, this makes the charger dangerous everywhere.
This charger has very bad safety, stay away.
