We purchased the battery charger it had a 80 percent charge when we received so it didnt talk long to charge it to 100% anyway the battery was completely dead and within a few minutes the truck turned on and it only used 2 % to charge it! I totally recommend this charger!
I bought this product because my car battery was starting to give me problems, and I wasn't convinced that I needed to change it yet. I made a careful comparison with similar products before buying, and made my decision based on capacity and price. Within days of buying it, it saved me from being stranded on several occasions. I even helped another driver whose battery suddenly died. I haven't used it to charge a phone or a laptop, but these are possibilities that make this product even more attractive. I highly recommend it.
I bought the butter 2500 first. I liked it so much that I bought 5 of the 5000 so I can keep 1 in every vehicle and have a extra one for when I go fishing.
I used once I needed it and it worked like a charm!
