These're new tools make by http://www.powerzall.com/ that transform your Dewalt, Makita, Bosch and Ryobi batteries into the best portable charger for all of your mobile devices. You can view the news here http://www.10news.com/news/local-inventors-new-device-could-help-keep-up-communication-during-emergencies-10182013 Product is available for preorder on Kickstarter http://www.kickstarter.com/projects/240165232/powerzall-the-fast-smart-and-powerful-portable-cha

older DCB200 and 201 don't have the battery gauge. So having the LEDs for reading battery can be useful. The front of the DCB090 doesn't snug tightly on the battery, you can wiggle it rather a lot, which causes the battery contact to be moving and loosen over time.

I'm learning and you are really teaching me. I really thank you for that and there are still very much that I don't understand. There may be really trade secrets in the battery, or said so by the different manufactures. When I look from the engineering stand point, in the core of Dewalt battery is just a package of power cells made readily available to the public by other companies such as Sanyo, Samsung .... These cell are one of the best out there and the specs of those cell are designed by the battery manufactures, not a secret sauce that made up by Dewalt. Dewalt just simply integrates one of the best batteries into their package. I hear you said but I think it's just smoke and mirror that you said they have magic way to use the cell battery better than it was designed for. Admittedly, Dewalt makes kick butt tools but it's the motor in drill that deliver the power and the drill simply draw needed current from the battery. When I tried Dewalt drill with a Milwaukee M18 battery or a Makita or a Bosch battery, the drill work the same way. There's no magic here in the Dewalt battery. Agree that you are very right about the state of the market for portable chargers. The market is saturated with low end portable charger products and none of them really stand out. At this point, all I can do is trying to make the best device, not one of the same as the crowd and let the consumer figures out which one they want to buy. I think we really got a very good discussion that many of the readers will find it very interesting to read and I salute you for following up with a new bee like me. Cheer and let all try to make better tools for the customer.

Sorry that I was a little too harsh. I understand the safely requirement to develop a product that can safely use its battery. I tested quite a few types of batteries, some are really good that I would not want to mention here but those batteries do manage its battery better by having a management board on the battery that shut itself down when the voltage drop below the low limit. Dewalt 20V however has a very simple management board that does not fully protect itself from being overdrew. That is the fault of the battery, not the fault of the attachment device that needs to use the battery. It's Dewalt's inefficient design of the 20V system is the problem. Instead of they only need to have one good battery management board on the battery and no battery management on the attachment devices that uses the battery, now they have battery management board on every attachment devices. Go figure! PowerzALL recognizes this limitation of the Dewalt 20V battery and fully implemented a safety protection for shutting down the adapter when the Dewalt battery's low limit is reached. Think about car's battery for a second, when a car battery went bad, it's the fault of the battery and the battery manufacture must honor their warranty, don't blame the car that uses the battery. Dewalt should really go back and design their battery better. I do present PowerzALL and I just point out the issues and compare the facts to educate the readers. Dewalt is a very reputable brand that no way that I can compete with. However there are rooms for improvements that I believe the PowerzALL brand can bring real value for the consumers by building a small product with more advanced features. I really wish to collaborate with Dewalt but they don't seem to be interested.

I totally respect Dewalt but scare tactic is not the right way to treat the consumer. I don't see Apple void their warranty if someone plug a cable into its phone. So why Dewalt can't let people use more of their battery? Or the Dewalt battery is not good enough and they afraid to let people freely use it?

The best way to find out is testing yourself. Get 2 of these, Portapow USB Power Monitor. http://www.portablepowersupplies.co.uk/portapow-usb-power-monitor/ You can plug them in the USB ports and see for yourself. Right on the package of DCB090 it says 1.5Amp isn't it? PowerzALL is optimally designed to fit on 18V and 20V lithium ion battery. It even has feature to protect the Dewalt battery better than the Dewalt battery itself has. I love Dewalt products but there's just something might be better out there believe or not!

The DCB090 is not so good that Dewalt doesn't want to show you any product spec. DCB090 only delivers 1.5 amps for both USB ports, each can give at most 1.3 amp on Apple device, and it only charge Android at max 0.5 Amp. Worst of all, it doesn't even fit tightly on the battery that Dewalt made. If you need to see the remaining battery capacity, you'll need to remove it from the battery and then put it back in. Check our a new after market part by http://www.powerzall.com/ that also fits on Dewalt 20V max batteries and they are running a Kickstarter project to manufacture. http://www.kickstarter.com/projects/240165232/powerzall-the-fast-smart-and-powerful-portable-cha PowerzAll is a full 2 Amp x 2 USB outputs, optimized charge for any device and 50% smaller on physical size. Simply said, DCB090 is a device that everyone can make cheaply and PowerzALL is the first device that out performs every charger specs in its class.
