I lost my 110v plug in ac/dc adapter for battery charger, however, I still had the plug in for my car. Searching for the correct 110v adapter was a chore I wish on no one and when found it was almost $20!!! I found this item while doing a new search and for the price I bought one, and to my surprise it has worked great. I've also brought it to work and used with my cell phone car cable to charge my batteries at work. Well liked and used. Great product and price.UPDATE!!! 8.15.05 Today I mailed my charger back to the company under warranty because after 1 month of usage it quite working. If it is covered and replaced with no charge I will once again update this review. Until then I can't recommend itUpdate!!! 9.26.05 Today my charger was returned by the USPO and marked as "UNCLAIMED - RETURN TO SENDER". I tried a search for this company to get a phone number and no luck. This was a total was of my money and energy Do not every buy anything from "Wireless Technologies"Also if I could my star rating would be ZERO!
