Amazing! Save My Money!

Great product. I'll buy again. Highly recommended. This has saved two AGM batteries for me so far.

Very Nice

Nice, reasonably compact for the power it generates, don't loose the manual, the little flashing light codes are not intuitive but I like it way better than others I bought.

Stay Charged

Needed something to keep my battery charged on a vehicle that is driven infrequently. I installed CTEK charger to maintain the battery and every time I go to start the vehicle the battery is fully charged.

Best Charger Ever

This is the best charger ever. I have a lead plugged into my motorcycle and 2 cars and I rotate it between the 3 of them and they start up like the battery is brand new. This will pay for itself just in not having to buy a new battery. Don't go cheap as this is the best and well worth it.
