A compact (but not tiny) device, the TECC Arc 5s has a reassuringly solid feel and build quality and comes in a range of vibrant brushed gunmetal colours with stainless steel threads and a spring loaded 510 connection.

New with the Arc 5 is an improved top fill system. Simply press the button on the side of tank at the top and push to reveal a filling port.

At the base of the tank you'll find the airflow controls. Open wide for an airy vape, close off for a tight restricted vape or use anywhere in between to suit your personal preferences.

The device also comes with stealth mode. Unfortunately, this doesn't mean that the device becomes invisible, but does mean you can turn off the display - handy for a discreet vape in the dark. To enable simply hold the power and down buttons off at the same time until the words Stealth On display on the screen.

You can also use key lock mode to prevent accidental changes to the wattage levels. Simply hold the up and down adjustment buttons down at the same time until the screen displays lock - repeat to reverse the process.
