1. The Basics
• The top light is blue and it is associated with the pack’s
charge. When the pack needs recharging, the blue light will
blink rapidly, approximately every two minutes. This light
will also blink when you first place a battery into the pack for
charging. The number of times the blue light blinks indicates
the number of times the pack can charge the battery before the
pack needs recharging.
• The bottom light is red and it is associated with the e-cigarette
battery’s charge. The red light will glow when the battery is
properly loaded into the pack and the lid is closed. The red
light will stop glowing once the battery is fully charged.
CAUTION: It is recommended that you keep blu e-cigarettes in
the pack at all times when not in use. Carrying the e-cigarettes
outside of the pack (e.g., loosely in your pocket or purse) may
cause them to activate and overheat.
2. Charging the Pack
The pack is shipped with some charge already; however, for
best performance with first time use, it is recommended that you
completely charge the pack before using it.
To ensure you charge the pack correctly, please follow these
steps:
To charge with a USB-compatible device:
1. Plug the enclosed USB cable’s large end into the USB-
compatible device.
2. Plug the USB cable’s small end into the bottom of your pack.
