Rated 5 out of 5
I've used it for about a year now. Its great for charging my phone all the time. Fits in my pockets with a 2 AH battery. I like that you can just change out the battery with a charged one. Much better then a battery bank that you have to charge before use.

Great little addition
This is a great tool to have if you are out and about with no way to plug into an outlet to charge your phone. It’s also great if the power goes out.

Good idea and great backup for USB charger...
It's on the more expensive end and the packaging is super frustrating (and probably not environmently friendly either...

Great little charger
I’veused this outside for phones or when we lost power, it only puts out 1.5 amps so if you want to charge an iPad it will drain a small battery quickly. I have 3,5, and 6 amp20volt batteries which can supply enough to keep you going for a while

Great Idea, Useful, but misses the mark of perfect
Like a lot of people I have a bunch of the DeWALT tools and batteries and the collection is get larger. I am frequently at places where there is either no power or it is hard to get to, and thought this would be perfect for the cell phone, tablet and whatever else can be charged via USB port. For celll phones, this is great. It will charge 2 without problem. When it comes to iPads, it will only handle one at a time and nothing else. At 1.5 amp output, it is just not enough to do much more than phones. I will have to say that DeWALT missed the mark here, hence the “average” rating. In this day, where almost everyone is working from tables it would have been better if this had been designed as a 2.5 or 3 amp output which would allow both ports to be used at any one time. Surely their batteries can handle it as it would be less than 1 amp from the battery to do this. At the price they get for this, I would have expected better. While I would recommend it, the recommendation will be with a caution about its limitations. Hopefully, DeWALT will improve upon this design, double its output and make it a full 5 star design.

Great idea - recharge cellphones when power is out
Works well, a very good standby power source. Just make sure your batteries are fully charged before using this adapter.
