I think that the device is worth the money. Charged AGM batteries for 70 and 105 Ah, the charger did a great job. It's nice that there is information not only on current and voltage, but also on the accepted amount of battery charge. It is not clear why it only charges up to 95%. Then you have to reconfigure the maximum current, then they gain another 3%. With its pros: - Compact - Inexpensive - Functional - Informative screen - Ability to connect to the battery without removing it from the car (without disconnecting the battery from the car network) Cons below: It does not draw a current of 20 A, a voltage drawdown is formed.
