Robust simple construction, Practicable

The device makes its metal housing makes a robust impression, which is disturbed by minor details something about quality haptics, such as shaking the device slightly because some screws in the base plate produce further stand out as the feet, line performing seem a bit "cheap". We must all look at the price but also in relation. The fully-insulated terminals are OK.

The charging circuit with thyristor is simple but effective, when the battery is fully goes back to the power, the simple electronic circuit limits the voltage to about 14 volts, because you do not pay close attention to the end of the charge then. (In the car the battery while the engine is running even with 14, operated x volts).

What you should consider: current is fixed at 10 A, more lead-acid batteries, for example for the car to cope with the power in any case, with smaller battery definitely take a look at the technical data of the batteries, the indication 5 Ah - 200 Ah as somewhat optimistic because smaller batteries with eg 5 Ah or 10 Ah sometimes may not be loaded with 10A.
