 Product Description


Eleaf LCD Voltage/Wattage Meter 


The Efest LCD meter is a compact and handy tool that functions as an inline Ohm, Voltage and Watt meter. This meter is equipped with an easy-to-read LCD display and features a 510 connector on the battery end and an eGo connector on the atomizer end. This meter is capable of displaying no-load battery voltage and on-load atomizer resistance, current voltage and wattage. The benefit of testing with on-load condition with a quality battery is the voltage will remain as advertised during usage, as compared to a bad battery where the voltage will drop significant during usage.



  • LCD Screen
  • Real-time resistance/voltage/wattage display
  • Short-circuit Protection
  • Over-voltage and Low-voltage Protection
  • Over-current Protection



  • Size: 47mm x 22mm
  • Material: Plastic tube with stainless steel structure inside
  • Input voltage: 2.5 to 6.5V
  • Testable wattage: ≤100W
  • Maximum current: ≤10A
  • Resistance range: 0.5 to 10Ω (will not test loads with lower than .5Ω)
  • Output voltage: 2.5 to 6.5V


Package Includes: 

1 - Eleaf LCD Voltage/Wattage Meter 



  • No-load Condition: When only connecting to battery, press the battery button, the LCD Screen will first display "NoΩ"(meaning no resistance), then the voltage of this battery.eleaf-lcd-meter-no.png
  • Loaded Condition: When connecting to battery and atomizer in the same time, press the button, the LCD Screen will first display the atomizer resistance, then the current voltage and wattage after 1 second.eleaf-lcd-meter-watt.png
  • Short-circuit protection: When the resistance is lower than 0.5Ω, the LCD Screen will show "E1". Attention: The LCD meter is not self powered, this meter requires you thread this on a power source.eleaf-lcd-meter-e1.png

Note: The LCD Meter cannot test the atomizer resistance when only connecting to an atomizer, as it has no power without a battery.



Warning: Use special caution when working with Li-ion cells, they are very sensitive to charging characteristics and may explode or burn if mishandled. Make sure the user has enough knowledge of Li-Ion rechargeable batteries in charging, discharging and assembly before use. Always charge in/on a fire-proof surface. Never leave charging batteries unattended. We are not responsible for damage if there is any modification of the batteries/chargers in any form or shape (including pack making). We are not responsible for any damage caused by misuse or mishandling of Li-Ion batteries and chargers. We only recommend using Lithium Ion rechargeable batteries with a control circuit (protection PCB) to assure safe charge, discharge, etc, use of lithium ion batteries without a protection circuit is potentially hazardous.

route66vapor.com will not be held responsible or liable for any injury, damage, or defect, permanent or temporary that may be caused by the improper use of a LI-ION battery. Please have a basic understanding of the batteries you are using and how to care for them properly.
