The biggest advantage of the Bull 3-bit USB charging socket is that the 3 USB charging plugs are on one panel, which can charge 3 electronic devices at the same time. And these three USB ports can intelligently distribute current and intelligently identify devices, which can reduce the damage to our mobile phone batteries.
That depends on how automated the \"automatic\" charger is.
If it is a lithium battery charger, it can be said that the charging circuit is very mature, the chip programmed automatic control ability is very high, the most common are with the control chip, can certainly automatically adjust the charging current, after the battery is fully charged to reach the preset voltage, automatically converted into a small current trickle charging.
Electric vehicle battery charger is the same, the finished charger, the protection function is very perfect, from 0 voltage recovery charging, low voltage protective charging, normal voltage section of current charging, to the end of the charging small current charging, charging full voltage trickle charging, the function is very perfect.
The kind of 5, 7 nickel-metal hydride battery charger sold on the market, it is not necessarily, some with automatic control, some is a current (usually 70ma-150ma) has been charged, if it is a nominal 300ma or more current nickel-metal hydride battery charger, most are with automatic charging function, nickel-metal hydride battery charger, is by full battery voltage will produce negative voltage drop, To control the charger's current.
