Some noted the fit is "snug" initially and doesn't fully slide onto larger 5AH batteries. Great for job sites, camping, and power outages.

It does what it's supposed to do

For the price this little thing does a lot, and does exactly what I want it to do - be there in an emergency. I live in an active part of tornado alley so in the spring I spend some time in my basement riding out T-warnings. I have charged two phones from 20% to full with a 5AH battery and the battery still shows full charge. The light is bright. Is it bright enough to find someone lost in the forest? No. Does it light up a dark basement well? Yes. One thing to note is that while it fits well on smaller 1.3AH DW batteries, it doesn't fully slide onto 5AH XR batteries for some reason. It still works though.It's easy to use and definitely worth the price. I'm happy.

Buying another...

Works perfectly with all of my DeWalt 20v and 60v batteries. Charging is excellent for any phone that I've tried with a quality cord. The small light isn't the brightest, but it works well and is better than most of the old C and D battery flashlights, with a whiter and longer lasting LED of course.

Very Nice Battery for Camping

Weve used this while camping Thanksgiving weekend. It charged my phone fairly quickly. I was almost at 100% from about 19% in less than 2 hours. My husband and I both charged our phones at least twice, and it still had power.
