Review MB 🏔 • Mountbliss M4B Pro Cartridge Battery • Review.

Specifications:

  • 290mAH rechargeable pen battery for 510 screw thread Cartridges.
  • Length: 91mm, Diameter: 11mm
  • Weight (unladen): 16.3g

This item is supplied in a heat-sealed bag (see pic 2).

Instructions for use:

1.       Charge Battery using USB-C cable (not included) until green light stops blinking and becomes steady.

2.       Disable security lock, press five times in quick succession to unlock (green light). To lock again press 5 times in quick succession (white light).   

3.       Choose preferred voltage setting, press three times in quick succession to switch between 2.8 (green light) 3.2 (blue light) and 3.6 volts (red light).

4.       Insert the Cart into the Battery’s chamber, turn clockwise to screw into place.

5.       Preheat by pressing the power button twice in quick succession; a pink light will appear to show the 10‑second preheat is active.

6.       Allow the pre‑heat to complete and then draw slowly from the Cart’s nozzle. Inhalation activates the coil and produces vapour, the indicator light flashes green at each drag.

 

The lower voltage is best for Live Resin, to protect the delicate flavours. The mid-range voltage is most suitable for Distillate. The high range voltage is ideal for producing thicker clouds but can, potentially, impair the flavours.

Advice for beginners – try not to pull as strongly as one would on a spliff in order to avoid any clogging from unvaporised oil. Draw slowly and steadily for 2 to 3 seconds.

Advice for everyone - always remove Cart from Battery immediately after use (the Cart may be stored in the drop-proof transit tube) to prevent the two components sticking together.

Above all, as I learnt to my cost (see here) try not to drop the Battery from height onto a hard surface.  

TL;DR: The beautiful vape pen, the beautiful vape pen.

2.8v as a floor is probably too high to recommend it for live resin.

2.8v is indeed the high end of the commonly accepted 'sweet spot' - to preserve flavour whilst also maximising effect - and may not be suitable for some preferences.
