basic protank as shown in the myepack link above charges of usb they are ok starters but really you need two of them so you always have one ready to go, how long they will last before charge depends on how much you vape.. half a day.. 1 day.. really not easy to tell.
as for the rest with those you get a basic tank for your juice and replaceable heads pack and usb charger so only thing needed really is juice and a spare.
the market is flooded with 1001 diff types so really its impossible to say ok get this kit and that tank etc without knowing budget.
If your serious about vaping then i would honestly forgo the ego/protank/evod entirely and go straight for the next level up like an MVP. cost is going to be not much more tbh that getting 2 protank kits and in fact may even be cheaper and you'll get a far better vape from them, better battery life, a few added features like variable voltage etc
shown here they come in gunmetal, silver, blue and black i think.
Kit Contents
1 x iTaste MVP
1x iClear30 Dual Coil Clearomizer with rotatable drip tip
1x USB cable
1x Beauty ring-thread cover
1xTransparent carrying case
enough for one person without the need for a second unit.. you can get spare iclear30 heads for a couple of quid from the same site here

the mvp will last a couple of days before charging ( and if i recall though otehrs will confirm can be charged and used at same time so when running low just plug in USB and carry on vaping.
this will work out cheaper than buying to protank kits and is a far superior device
