Welcome to ECF and vaping, celestine!
The simplest and easiest to use e-cigs probably are the two-piece, cartomizer-based models. [Cartomizer = integrated atomizer and cartridge] You just screw the prefilled cartomizer into the battery and vape. No messing with filling cartridges with e-liquid required (although they can be refilled a few times if you choose).
The KR808D-1 is the most popular model. [Since KR808D-1 takes a long time to pronounce, I call it the Kreight. No one else does, however.] Here's a photo:
The standard Kreight has a moderately long 280 mAh battery, which puts the complete e-cig in the "Mini" size class (along with such models as the Joye510, M401, and DSE901). [mAh = milliamp hours. The higher the mAh, the more puffs per battery charge.]
However, quite recently both an extra long 380 mAh battery and a short battery have been introduced. [I'm not sure what the short battery's mAh is, probably around 200.] With the XL battery, the Kreight is almost the length of a "Penstyle" (e.g., DSE801, BE112, M201, Joye302). Shown here is this XL battery (with cartomizer) from China-based Heaven Gifts, only one of the good suppliers for this size.
With the short battery, it becomes a "Super-Mini," one of the longer ones (e.g., M402 or Joye306), approximately the length of a 100s cigarette. Shown here is the Vapor4Life "Vapor King" brand, the only supplier I know of for this size.
Until recently, all Kreights had automatic switch batteries (i.e., sucking on the e-cig turns on the battery to vaporize the e-liquid in the cartomizer) such as those shown in all the photos above. A couple months ago, however, manual switch batteries came on the scene. These have a button on the side that you press to turn on the battery. Here's a photo of the PureSmoker "Ace" brand manual battery (again, only one of the good suppliers):
So lots of choices. You would know better than I which size e-cig and switch type might be most suitable for you. For example, would that small button manual switch battery be difficult to maneuver?
To recharge your battery on the go, you might want to get a PCC (personal charging case), available from most of the suppliers who carry the Kreight, such as CigEasy. [NOTE: The XL battery can be charged in this PCC, but is too long for the case to be closed.]
And, regardless of battery size and type, there is a wide range of flavors and nicotine levels (and colors) available in the cartomizers. And the compatible GreenCig cartomizers (available from NHaler, which also carries the Kreight series) come from a different manufacturer and provide a different vaping experience.
Along the way, I have deliberately dropped names (and included links) of some of the major suppliers of the Kreight model. [Remember, 'Kreight' is just DaBoomVape shorthand for KR808D-1. No one else will know what you're talking about if you call it a Kreight.
] To learn more, visit their websites and ECF forums (and any of the other good KR808D-1 suppliers you learn about) and the KR808D-1 Model Specific Discussion forum.
BTW, Kreight cartomizers can be used with most big battery mods, the larger size of which may be a plus (or minus) for you.
For more information about these mods – and virtually all the other e-cig models – you may want to explore the WWV Illustrated Guide linked in my signature. And to interact with others with various types of disabilities, check out the Wrecked & Bonkers forum and social group. [I had thought their focus was strictly mental health issues, but a quick browse there indicates other medical issues as well.]
All the best, celestine!
[Personal Note: My wife has MS, not the same thing as Cerebral Palsy, but her symptoms are similar. For example, her vision has been effected: her eyes check out fine, but she has photophobia (wearing sunglasses indoors and a second dark pair over those outside) and also is unable to read, watch TV, or use a computer, without feeling dizzy and getting a headache. Also her limbs are weak and she is very unsteady, using a walker to ambulate and her left arm often shakes. She is not, however, a smoker or vaper, so this ramification has never come up to us.]
