The highest capacity grew up to 250 W; it's obvious from the name of the plane. 60 A is a restriction of output current. Ampere is an input restriction for charging the storage batteries with USB. The plane is protected against incorrect adjustment of a storage battery. A safeguard is enhanced. Temperature control for stainless steel materials is added, and it is a part of software and its updating is available for DNA 200 and DNA 75.
