Hello All,
The
Dewalt DCB090 is a device that is attached to a
Dewalt 20 volt battery. This add-on is essentially a battery pack. It has two
USB-A ports and allows the user to charge small electronic devices. The unit itself is charged by attaching it to a Dewalt 20 volt battery that is in turn plugged in to the Dewalt battery charger. Once charged, the add on is disconnected. Fully charged, it holds a 6 Ah charge. I carried it with me on a 5 day kayaking trip to the San Juan Islands and used it to recharge cell phones and hand-held GPS units.

In researching, I found a much less expensive unit. It is simply a USB adapter. You attach it to a charged battery pack and then pack both of them for recharging electronic devices in the field. See

I have no experience with this product and can offer no recommendation for it.
