POTV Launches Its Own XMAX V4 Pro: What UK Owners Should Know
Share
Planet of the Vapes (POTV) added a POTV-branded XMAX V4 Pro to its range on Friday 16 October 2026, according to its store product record. The US retailer also published Tyler Hixon’s review that day, giving its own assessment of the device alongside the new listing.
A check of POTV’s full store catalogue shows no earlier V4 Pro listing; its previous branded XMAX devices were the POTV XMAX V3 Pro and the POTV XMAX Starry V4. The base XMAX V4 Pro, made by XMAX/Topgreen, had already been sold by other retailers earlier in 2026. The news here is POTV’s edition and its first published test, rather than the arrival of the underlying model.
This article draws on POTV’s published product page and review, XMAX’s official listing and POTV’s shipping notice. It is not a Vapetrix hands-on test. Those sources leave two specification differences unexplained, while POTV’s international shipping pause limits the immediate options for UK buyers.
What’s in the POTV edition?
On its product page, POTV lists a device bearing its logo, a POTV Dimpled Glass Stem and a POTV V3/V4 Pro Glass Adapter. Its box contents include an installed Samsung 35E 3500mAh 18650 battery, a dosing capsule and a USB-C to USB-A cable.
POTV also lists a cleaning brush, alcohol pads, cotton swabs, three glass adapter mesh screens, two oven mesh screens, a screen removal tool and a manual. The retailer states a one-year warranty and says the serial number sticker on the bottom of the box is needed.
POTV lists a variable airflow slider, Session mode with a four- or six-minute timer, and On-demand mode. Its stated temperature range is 100°C–220°C (212°F–428°F), adjustable by single degrees. The retailer says the replaceable battery supports USB-C pass-through charging, allowing use while charging.
What POTV’s own review found
In POTV’s review dated 16 October, Hixon concludes that the device trades flavour for punch. This is the retailer’s testing of a product it sells: its reported results should be read with that relationship clear.
Hixon reports dense vapour from slower, easier draws, with flavour noticeable at lower temperatures but fading quickly. His favourite session was around 177°C (350°F); he describes a harsh taste at the top of the range. His verdict favours the V4 Pro for an easier draw, while giving the V3 Pro the edge on flavour.
In POTV’s testing, Session mode reached about 199°C (390°F) in approximately 22–27 seconds. On-demand heating from fairly cold took about 13 to over 20 seconds, falling to about 10 seconds for successive draws when warm. Hixon says he mostly used Session mode.
The review reports that the widest airflow setting is only slightly more open than the V3 Pro’s. Hixon identifies the extra range for tightening the draw as the larger benefit, and says the slider can be feathered with a finger during a draw. He found around 0.13g of material worked best; loads of 0.03–0.05g also worked with harder draws.
POTV recorded 15 full six-minute sessions at about 199°C (390°F), roughly 90 minutes of runtime, with a full charge taking about two hours and 50 minutes. Hixon also reports that the glass mouthpiece holds normally but can come loose with a hard shake.
POTV edition versus the maker’s listing
POTV describes its edition as using hybrid heat. By comparison, XMAX/Topgreen’s official V4 Pro listing describes convection heating. The battery specifications differ too: XMAX lists a 2550mAh cell, whereas POTV lists a Samsung 35E 3500mAh cell in its box.
| Stated specification | POTV listing | XMAX/Topgreen listing |
|---|---|---|
| Heating description | Hybrid heat | Convection |
| Battery | Samsung 35E 3500mAh 18650 | 2550mAh 3.7V 18650 |
| Temperature range | 100°C–220°C (212°F–428°F) | 100°C–220°C (212°F–428°F) |
| Modes | Session and On-demand | Session and On-demand |
| Airflow | Variable slider | Adjustable |
| Charging connection | USB-C; pass-through use | Type-C; 5.0V/1A |
Neither source explains the heating terminology or battery difference. These descriptions therefore need to stay attached to their respective listings; they do not establish an internal hardware change. XMAX separately lists a stainless steel heating chamber and an isolated air path.
V4 Pro versus V3 Pro, in short
POTV lists a colour OLED display that rotates 180 degrees for upside-down bubbler use. Its product page says the USB-C port has moved from the V3 Pro’s bottom position to the back, with battery access now underneath. In the review, Hixon says pressing all three buttons together flips the screen.
POTV’s assessment does not present the V4 Pro as a clear-cut upgrade. Its reported easier draw comes alongside its preference for the V3 Pro’s flavour. Taken together, the retailer’s findings make draw preference and flavour priorities more useful comparison points than the model number alone.
What it means for UK buyers
On 18 October 2026, POTV’s US store displayed the notice: “We've paused international shipping for now.” UK buyers therefore cannot currently order this edition directly from POTV. Our earlier Journal article on the shipping pause covers that restriction.
The standard XMAX V4 Pro is already sold by UK retailers, so UK owners are more likely to have that version than POTV’s edition. POTV’s review is still a useful account of how the V4 Pro platform behaves, but the unexplained listing differences are a reason to keep its claims and XMAX’s own specifications clearly separate.
Glass, bubblers and water pipe adapters
Vapetrix lists its V3 Pro and V4 Pro accessories for the standard devices. Our stems, bubbler and water pipe adapter need a compatible black base/mount, which is not included. Fit with POTV’s own V3/V4 Pro Glass Adapter is unconfirmed, so POTV-edition owners should check which base holds their glass before ordering.
Our listings include 60mm shaded black stems in pairs, 110mm straight or 110mm angled stems in pairs, and a single 130mm stem with internal glass cooling beads. The Vapetrix glass compatibility guide sets out the standard V3 Pro/V4 Pro fit information, and our water pipe and bubbler guide covers water setups.
Vapetrix also lists a 130mm glass water bubbler with a curved mouthpiece and a stepped borosilicate glass water pipe adapter, approximately 50mm long, with 10/14/18mm male fittings. Both need that compatible black base/mount, which is not included, and neither has confirmed fit with POTV’s adapter.
The bottom line
POTV’s launch adds its branded package and a detailed retailer review to the V4 Pro story. Its findings favour easier draws over lasting flavour, while its listing differs from XMAX’s on heating description and battery capacity. For UK readers, POTV’s shipping pause and the unconfirmed adapter fit remain practical limits.
