100 mah= 1 hour normal vaping before requiring recharge. Understand if you are using a higher voltage via a variable voltage PV the batteries will drain quicker. So a 1100 mah battery will last approx. 10 hrs before needing recharge. Disposable batts are good for 250- 300 recharges. Most of of prefer manual push button batteries because it put us in control of the vape. Auto batts have an auto shut off feature and also because the batts have air holes are more susceptible to damage from juice.
Threading
There are mainly 2 types of threadings- less common 808 and most common 510- depending on the threaded PV you choose you have to use matching accessories.
Different PVs
eGo Class/ Style- 510 threading. Manual Batteries:
JoyTech eGo fires @ 3.3 volts, SmokTech eGo fires @ 3.7 volts and the Riva/ Kgo fires @ 3.7 volts- come in 650, 900 or 1100 mah depending on the manufacturer- most popular 510 threading/ connection and are manual. I own a Kgo and I LOVE it. Have used the JoyTech eGo and prefer the Kgo because of the higher voltage.
JT eGo Starter Kit cost anywhere from $50- $80.
Riva/ Kgo starter kit costs about $40-$50
Kgo Review
Mini Variable Volt PV: 510 threading/ connection. Manual Batteries.
Twist comes in 650, 900 and 1000 mah. Dial very narrow/ smooth and not easy to turn. Voltage numbers very hard to read/ invisible. Button occasionally sticks.
Vision Spinner comes in 400, 650, 900, 1100 and 1300 mah. Wide knurled voltage dial easy to turn and easy to read voltage markings. 1300 mah Spinner is the same size as 1000 Twist.
Both variable voltage PVs above fire from 3.3-4.8 volts.
I owned the Twists and now use them as backups because the dial was hard to turn and I could not clearly see the voltage markings.
1300 Vision Spinner- 113mm or ~4.4 inches long; 16MM WIDE, 2MM WIDER THAN A STANDARD EGO
1100 Vision Spinner- 119mm or ~4.75 inches long
1000 Twist- Length 120mm(4.75")/Diameter 14mm
Advantage of the VV- when stressed and need a stronger hit I can easily and quickly dial up the voltage.
Above and beyond the above "disposable" batteries are VV/ variable voltage Mods. Batts are separate from the tube and very inexpensive. The Mods also have a wider range of voltage. They are much larger than the above PVs BUT batteries can have 2200+ mah.
If going this route the Vamo receives high praise and can also be "broken down" into a smaller PV.- about 80 for a full kit.
Will post more reviews for the Spinner and Vamo- if anything it will give you an idea of the size.
