Ego batteries are cheap and compact, proving an ideal starting places for vapers. Each battery consists of stainless steel shell containing a high-grade rechargable lithium cell by HGB. Each will typically last for many hours of continuous vaping and so in normal use last much longer. In other words, less recharging and less hassle.
The device is activated by a manual button switch that glows on activation so you can control exactly how long the device fires for. The button also has a 5-click on-off function so that you can prevent it accidentally activating when not in use. It has two different connectors: a smaller female 510 thread and a male Ego thread. These are standard threads in the industry and so the batteries are compatible with a range of products. The battery discharges at approximately 3.9V of electricity. This will provide good performance on all sold attachments. A 420mA 5V USB charger should be used for recharging.
Battery capacity is measured in milliampere hours (mAh). More capacity means a larger battery and so longer between charges but also a larger device. Different people favour a different balance between size and performance. The total size (including threaded section) of the Ego batteries are 14mm thickness and 94mm length for 2200mAh.
