plus : - Well packed, looks nice. - Shown values on the display are as good as correct. (deviations are less than 2%) minus : - A piece of paper with full and clear explanation/description of the different "menu-items" would be more than welcome (or a website) - without extra cooling it can NOT give more than 2 Amps. = 25Watts for charging a 12V battery with power supply 12V, output voltage set to 15V and current limit set to 2 Amps. Setting more output Amps, makes the temperature safety kick in. (I tried with 2.5Amps ! and safety kicked in after 2 minutes) - The over temperature protection is a great feature, but it does not reset itself. It means that after an occurrence of over-temperature, the unit must be switched back on MANUALLY. The unit does not continue when the temperature goes below the setting. - The Ah counter gets reset when the supply is switched OFF. - Sometimes other values change while changing a specific value. (software problem ?)
