13.8V N557514 Replacement Charger for DeWalt Inflator Compatible with DeWalt DCC020IB 20V Air Inflator Power Supply Adapter

When I got my Dewalt tire inflator I considered getting the official ac adapter. But Dewalt charges so much for it. Thus I was very excited to see this alternative. We this you can keep inflating things to your hearts content without having to change batteries.Of course it's not as robust and heavy duty as the OEM item. It's a generic power supply with a small fan and is very basic plastic case. But as long as you aren't throwing it around, it should be fine.

This product (Mrgru Model BOT-5460200) is a power supply for use with the DeWALT DCC020IB Inflator tool. This device is designed to be plugged into a 120VAC outlet and will supply 12V (nominal) power to the inflator tool so that the tool may be used when a DeWALT-pattern 20V MAX battery is not available or its use is not desired.This product may utilize an A/C power input of 100 to 240-volts and 50 to 60Hz. This means that the product is capable of being used virtually world-wide. The product I ordered and received came with a power input cord designed for use in the United States with its standard 120VAC 60Hz power supply. The power output of the unit is actually 13.8-volts DC with a maximum current output of 10 amps. The 13.8-volt value is the charging voltage in an automobile with a 12-volt power system which can also be input to the DeWALT DCC020IB Inflator tool when using the DeWALT-supplied 12V input cord included with the inflator.This product is a replacement for the DeWALT N557514 power supply that is sold as a separate accessory for the DeWALT DCC020IB. The DeWALT product costs a little less than twice the cost of this replacement product. In some ways, this product is superior to the DeWALT product. When I looked over and then tested this product, I noted several impressive features. First, the device has a pilot light built into the power block. The pilot light was illuminated green when the device was connected to the inflator and plugged into the power outlet. When the inflator was turned on and began to run and draw current, the pilot light changed to being illuminated red indicating that power was being supplied. At the same time, the small cooling fan in the end of the power block turned on and was moving cooling air through the power block. I ran the inflator for better than five minutes and the power block never got warm thanks to the cooling fan’s operation. I also noted that this unit is capable of up to 10 amps output, which at 13.8 volts provides 138 watts of power. The DeWALT N557514 power supply claims a power output of only 100 watts. Lastly, the DeWALT N557514 power supply has both the input and output cords permanently affixed to the power block. This unit has the output cord permanently affixed but the input cord plugs into a socket in the power block. This makes the product a little more compact and easier to find a place to store in the storage case, if one is used. If the manufacturer would like to make an improvement to the product, I would suggest adding a socket and plug arrangement for the product’s output cord, as well.So far, I am impressed with this product and like it very much. This power supply is already stored in the custom-fitted case I have purchased for the DeWALT DCC020IB Inflator tool. I am waiting on the delivery of a large-capacity DeWALT 20V MAX-pattern I have ordered for this application and then my inflator kit will be complete.
