The Vapeccino Mate1 is available. I'm new and don't know if posting links to dealers is allowed so I'll just say that you can easily find it with a Google search. You just missed a big sale by about one day. I almost bought it but decided to buy the Infinix instead.
The Suorin Eva (posted above) looks similar to the Infinix but it has a 380mAh battery. One dealer says it will be available at the end of May.
If the ONLY problem with the Infinix is the battery, then why not buy another one? They're small enough to carry 2. The Ebay price seems high. I paid $10 retail for a pack of 3 pods from a dealer... actually ended up about $9 per 3 pack after a coupon and free shipping (over a minimum amount).
I also use the juul, Drop, Air, and Breeze (not a pod system).
I will probably stick to the Infinix for now. I’ve had no problems with it. We will see what new comes out in the near future. Maybe wait for the Suorin Eva.
