Cali Clear V4 — Specifications and How to Identify One
The Cali Clear V4 is two hardware generations behind the current V6. It is a 2g all-in-one disposable carrying the same liquid diamond extract at 90–95% THC — as with every generation, the oil is unchanged and the hardware is what differs.
Most people reach this page holding a unit they are trying to identify, or deciding whether a V4 someone is selling is worth buying. Both are answered below.
How to Identify a Cali Clear V4
Four identifying marks, ordered by how fast someone can check them:
- Packaging marking — The “V4” designation is printed on the bottom sticker and the lower side panel of the retail box, adjacent to the batch number and QR code.
- Shell — The V4 features a slightly rounded, cylindrical body that is noticeably bulkier and thicker than the sleek V5 and V6. It has a semi-glossy finish.
- Mouthpiece — The V4 uses a tapered, pointed mouthpiece. It is slightly wider than the V3’s extreme point, but noticeably narrower and more restrictive than the flat, wide-bore mouthpieces on the V5 and V6.
- Base — Look at the charging port on the base. Early V4 units use the older, trapezoidal Micro-USB port. Late V4 units use an early, smaller USB-C port. (If it has a modern, standard-sized oval USB-C, it is a V5 or V6).
If none of those settle it, the batch number on the box will. Look it up against our published lab reports — the batch record identifies the exact hardware generation it shipped in.

Note on measurement: We no longer stock V4 units for independent bench testing. The specifications above are verified from historical batch COAs and manufacturer data. “No longer stocked — not independently measured” is a row we are proud to publish, as it remains more honest than competitors who invent data for discontinued hardware.
Cali Clear V4 vs V3 — Telling the Two Apart
These are the two generations people most often confuse, because both are old enough that the packaging is unfamiliar and neither is on a shelf to compare against.
The single fastest visual difference: The V3 has a distinctly blocky, boxy shell with a very narrow, sharply pointed mouthpiece, whereas the V4 is slightly more rounded/cylindrical with a mouthpiece that, while still tapered, is wider and less extreme.
Secondary differences: The V4 packaging features a more modern, cleaner font and a slightly more matte box finish compared to the older, highly glossy V3 box artwork. Additionally, the V3 is strictly Micro-USB, whereas late-run V4s began transitioning to early USB-C.
Both generations carry the same extract base as the current V6. Neither is weaker than the other in specification, and neither is weaker than what is in production now. Full detail on the older generation: Cali Clear V3.
What Changed Between the V4 and V5
The transition from the V4 to the V5 was primarily about charging reliability and battery management:
- Universal USB-C Charging: The V4 was a transitionary model that used either Micro-USB or early, non-standard USB-C. The V5 standardized a modern, oval USB-C port across the entire lineup, making charging universal and reliable.
- Battery Management Upgrade: While both used a 300mAh cell, the V5 upgraded the internal PCB to ensure the battery could reliably power the mesh coil through the entire 2g of oil. The V4 was notorious for the battery dying before the tank was empty.
- Shell Refinement: The V5 smoothed out the V4’s bulky, semi-glossy shell into a sleeker, fully glossy cylindrical design, and slightly widened the mouthpiece to reduce draw resistance.
The extract, tank capacity, and mesh coil technology remained exactly the same between the two generations.
The Cali Clear V5 page covers that generation in full, and the Cali Clear V6 page covers what is current.
Is a Cali Clear V4 Still Worth Buying?
The extract is the same, so the question is not about the quality of the oil. It is about two other things.
Hardware. Whatever the V5 and V6 improved (USB-C charging, reliable battery life, better airflow), a V4 does not have. You are using older, less convenient hardware.
Age — and this is the part nobody mentions. A V4 for sale today has been sitting somewhere for a long time, and time affects a vape independently of whether it is authentic. Terpenes are volatile and degrade first, so an old unit can taste flatter than a fresh one of the same flavor. Oil darkens with age and light exposure. Lithium cells lose capacity sitting at partial charge.
None of that makes an old unit unsafe or fake. It means a genuine, authentic V4 can still be past its best, and the price should reflect that. If a seller is asking current-generation money for two-generation-old stock, that is the thing to push back on — see the Cali Clear price guide for the ranges.
Buying a V4 Safely
Age raises the bar on verification. A V5 still circulates legitimately; a V4 is old enough that “brand new, still sealed” deserves a second look.
Run the full check: scan the QR code, match the batch number against our published lab reports, and compare the packaging against the photographs on our authenticity guide. A batch number that does not resolve is the end of the conversation regardless of how convincing the box looks.
What to Buy Instead
Everything we stock in the 2g disposable range ships as the current V6 — same tank size as the V4, same extract, current hardware, and fresh rather than stored.
If you were buying a V4 for a specific flavor, check the Cali Clear flavors page first; most carry across generations. And if two flavors in one device appeals more than a generation number, the Cali Clear Dual Chamber is a different format rather than a newer version of the same one.

Yes. The V4 is fully out of production and has been superseded by the V5 and the current V6.
Is a Cali Clear V4 weaker than a V6?
No. Every Cali Clear generation carries the same liquid diamond extract specification. However, a V4 that has been stored for a long time may taste flatter as terpenes degrade, and it will test at the 80–85% range typical of its production era, compared to the 85–95% range of the V6.

Can I still buy a Cali Clear V4?
No, we do not stock the V4. We only carry the current V6 generation to ensure our customers receive fresh extract and the latest hardware with reliable USB-C charging. You can shop the current V6 lineup here.

How do I know which Cali Clear version I have?
Check the packaging marking, shell shape, mouthpiece, and charging port. If those do not settle it, look up the batch number on the box against our published lab reports.
