An electrical engineer's opinion
The current drain can be a problem. I measured the current drain with a meter. The charger draws 2mA when connected to the battery pack and not in use. With this current drain it will take forty-days to drain half of the charge from a 4AH battery. The charger has a microprocessor that will protect the lithium battery from full discharge damage by reducing the drain current to nearly zero when the battery voltage drops below a safe level.Despite this shortcoming I love the Dewalt 20V lithium family of tools and this charger. I bought a couple more chargers after buying and dissecting the first one. I bought one for my wife so that she can share my passion for Dewalt battery powered tools. However, I did modify the internal circuit so that the current draw drops to zero when the charger's output current drops to near zero. The modification includes a circuit (brassboard) that senses when the switching regulator goes into low power mode and then fools the microprocessor with a false low battery voltage signal thus bringing the current to zero. With this arrangement the charger goes to 'sleep' after the phone/pad is completely charged. I also boosted the output current to about 2 Amps and added a LED to indicate that the charger is on and providing power through the USB port.I would be glad to share this modification information free of charge to Dewalt or an interested Dewalt fanatic that is handy with electronic circuit construction. The modification requires electronic components such as a transistor, a diode array, a LED, capacitors and resistors. Surface mount components are preferred due to space limitations. Leave a comment if interested and I'll check for posts periodically over the next few months.

Great purchase
This worked so good. We went on a three day river trip and it was able to keep all of our stuff charged those whole three days. Definitely recommend.

For emergencies
It works perfect.We just had wild fires in CA(january/24). and with no power for 3 days i could charge my phone to read the news. I could charge my phone several times with one baterry.

Works better than expected
My husband is using his phone all day and has always had issues with his batteries not withstanding the amount on time being able to be charged as he works construction and mostly without electricity. This product works great for him and helps to provide power to his USB charging cords.
