As standard, our laptop charging trolleys include a 30mA RCD plug.  If the charging cable is severed or damaged in any way, the RCD trips and cuts off power instantly to prevent a live trailing cable.

Our unique designed electrical safety system which has been used in the tens of thousands of laptop charging trolleys we have built and sold over the years, which ensures electrical safety when powering multiple laptops and devices.

There are many effects which need to be taken into account when charging multiple power transformers which charge individual laptops.  There are very dangerous consequences of not getting this right and our Ultra Safe Charging System is safety certified to the highest international standards for this exact job.  This is required by law.

The Soft Start slowly phases in the electrical charging for the power strips to prevent an exponential power load from tripping the electrical circuit.   The mains power to the laptop charging trolley then passes through our unique electrical safety system.

When a battery has not been used for a long time and is completely flat, it can momentarily require an amount of power which far exceeds the circuit rating.  This is often the case in laptops where they have been left over a holiday period, or they are laptops which are old and have discharged quickly.

Our integrated surge suppression prevents the demand from overloading and tripping the mains circuit.  The soft start then phases in the banks of power distribution to allow the short demand to be spread over several seconds, again to protect the mains circuit.

Once the laptop transformers are charging in the laptop trolley, their capacitors will be brimming with charge.  If at this point the mains plug is removed from the wall socket, the transformers which are holding the stored charge will then be able to send their capacitive charge back down the to the plug.  When a user then touches the live and neutral pins on the mains input plug, it will produce a dangerous electrical shock as multiple transformers discharge themselves to the user.

The Anti-Backwash eliminates this risk by instantaneously by switching the electrical discharge within the circuit instantly the mains plug is removed and safely discharging the current.

In order to ensure a consistent and stable electrical supply to the laptop transformers, ensuring safety and increasing laptop lifespan, we integrate our mains conditioner which removes any nasty electrical surprises when connected to the mains.
