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.
