Multi-Functional USB Charger Adapter & 20V Battery Adapter Compatible with Dewalt 20V Battery, with 2 USB Ports & 1 Type-C Fast Charging Ports, with DC XT60 Port for DIY(1-Pack)

I love this thing! Constructed very well and easy to use. Once you use it, you learn quickly how to toggle between USB and power output through the cables using the micro switch. You get alot more for the low price and it doesn't feel cheap. Great for use where you don't have power readily available.

Arrived on time - well packed - works great - thanks!

I've only used this as a charger for my phone. It's definitely not a fast charger but it does the job when you're in the shop and don't have a regular charger handy. The slow charging speed is the only reason I didn't give it 5 stars.

Overall an amazing product for the price.* This adapter exposes a male XT60 connector and supports 20A. My testing shows that the low-voltage cutoff occurred around 15V. It uses a low-side N-MOSFET to control power to the XT60. The FET is a HYG011N04LS1TA, which has 1mΩ of resistance, and there is a 0.5mΩ shunt resistor for overcurrent detection. It uses a PY32F002A ARM Cortex microcontroller to handle power control. At 30A, this is 1.35W of loss within the FET and shunt, which is acceptable.* The adapter supports 2 USB-A ports and 1 USB-C port with PD. The left USB-A port and the USB-C port are on the same supply bus, so plugging in a device into both will force them both to output at 5V.* USB-C PD supports 15V/2A, 12V/2.5A, 9V/3A, 5V/3A (and allegedly PPS, though not tested). It cannot properly do 20V since it only has a buck converter internally and cannot step up the battery voltage. The USB-C port and the left USB-A port are both managed by a XPD740 controller combined with a HC8003 synchronous buck converter. With 18V input and 12V/2.5A output, I measured a conversion efficiency of 93.6%. Most heat loss was within the HC8003, which reached 162°F at steady state.* The right USB-A port is powered by a different controller and converter (IP6525).* There is an onboard switch with LEDs, so you could use the board directly without the plastic housing and the switch connected to the board via a ribbon cable.* The board is very cleanly soldered and assembled.* When a battery is plugged in and the adapter is off, it draws ~0mA of current. With just the USB converters powered, it drew 5mA while idle, and with the XT60 output as well, it drew 8mA idle.The cons:* Please label the adapter with the USB-C PD capabilities and also which USB A port is tied to the USB-C port.* The choice of male XT60 is very odd. Most batteries expose a female XT60.* The adapter is 30mm tall, when other basic adapters are only 20mm or so tall.The board is relatively complex. However, if the manufacturer is able to make this board at the current price point, then that is very, very impressive. Personally, I would have dropped the second USB-A port (i.e., IP6525 and inductor) and used a single chip solution (instead of an entire microcontroller) for overcurrent protection. I would be willing to pay more money if this was also able to (safely) charge the battery (e.g., using an IP2368 or something) with appropriate cell-balance circuitry.

Works great. I can run all of my 12v LEDs using this.

The led will light up when a battery is inserted but nothing else will work and I'm 2 weeks past the "30 day return window" I tried 3 different batteries and all of the usb as well as the wire outputs. Manufacturer reached out and sent me a new one that does indeed work.

Superfast charging for my galaxy s 22 ultra!

Stopped working after a couple of uses. Past 45 days and now I am stuck with a pretty lump of yellow.
