Review on 🔌 DROK Dual Power Adapter 3A/15W: 8-22V to 5V Double USB Cable Connector for iPhone, iPad, Nokia, HTC by Girish Underwood

After struggling with this for a week I was finally able to get it to charge my Samsung tablets as well as all my other products. The device has a port that charges the DCP with 1 ampere in the event of a short circuit between the data lines D+ and D-. The second port does not charge the DCP (Dedicated Charge Port) with more than 500mA, regardless of the state of the data lines. The ports are not labeled to indicate which is correct, you will need to swap them and see which is which. In no case could I get the device to deliver more than 1 amp to any type of load. It never delivers more than 1.5 amps. I bought a USB power meter and tested almost everything around the house. I've tested this with devices that draw between 1.7 (Samsung) and 2 amps (Apple) on their OEM chargers and it never went over 1 amp. When charging the DCP with 1 ampere, there is a significant voltage drop, which drops to 4.8 volts. When charging an iPad with a current of 1 ampere, it can withstand 5.05 volts. DCPs are also known as dumb charging ports - they're just a battery that needs charging, not a complex device like the iPhone with a complex charging protocol. USB rechargeable power banks/phone chargers/Samsung tablets are all examples of DCPs. If you short the data pins on the Samsung Dock connector, it becomes a DCP cable and charges the tablet, but very slowly and only when the screen is significantly off. My 7" tablet draws about 900mA at medium screen brightness, leaving only 100mA to charge the battery. Increasing the screen brightness removes that excess and you're not actually charging, just increasing battery life. So this is a dual 1.5 amp charger? no If one port is loaded with 1 amp, the other will drop to 500mA. It's a 1.5 amp charger, period.
