    The converter is well-designed and based on the XLSEMI XL4015 DC-DC buck converter. The XL4015 is capable of 5 amps continuous output, and testing confirms this. The metal enclosure acts as a heat sink and is attached to the PCB under the XL4015 by thermal foam. It does get warm at 4+ amps. Also inside are a few large capacitors and an inductor. The output sustains 5.3 volts as the specifications state, and it's impressively consistent as output increases. Efficiency is 85-88%. It has built in thermal-cutoff. The "fast charging identification chip" does not enable max-rate charging of iOS devices - they're limited to 1 amp. A red LED indicates power-on. The included XT-60 cable is pre-installed and perfect for hooking up to drone batteries. The barrel connector jack is a nice bonus. It's quite a bit larger than other parts available here, and more expensive. It's a great plug-and-play unit if you need to charge several USB devices at the same time from a drone LiPo through the XT60 connector.

    Apesar de ter vindo um com defeito, a banggood me reenviou outro e desta vez funcionou perfeitamente, usei apenas testando, mas carregou meu mi a2 sem problemas desta vez!!

    And they do their job fine. It's not Qualcomm Quick Charge, but it does outputs 1 amp to my phone and nearly two amps to my power bank. Each output can deliver at leas t three amps (my load couldn't go higher), and the voltage stayed stable. Excellent value
