Mine did however only times not. The price could not be much in it, which can break. What I saw, however, when I opened the unit, took my first time language.
In this context, the Note that you should know what you're doing when you electrical devices that operate at mains voltage disassembled !!!
No power switch, a transformer, a rectifier, a soldered (!) Fuse (15A) directly to the secondary side of the transformer (which, incidentally, was the fault why my machine did not work), an ammeter, which can serve at best as an estimate.
220V side of the transformer - cable through the enclosure, behind a plastic clip for strain relief, directly to the transformer (at least there is a plastic cover over it).
Secondary side - the wire constituting the winding has also the same used for internal wiring. Apart from the paint no further isolation. All connections have been carried out by means of receptacles. Except for the backup to the secondary winding - which has been soldered. Of course, self-supporting.
The ammeter initially did not display. After the same disassembly I found - can not, the hand rubs on the scale. After adjustment am back.
The achievable externally fuse is installed flush with the front panel of the device. And no fuse extractor here. So replace a lot of joy when, if necessary.
All in all, a device, which ensures battery charges, but the internal structure is the cheapest of the cheap ones.
