For a simpler threaded 510 battery compare the Yocan Ari Plus 900mAh battery, or the Yocan Ziva for a draw activated enclosed body. Black Note e-liquid needs a refillable pod system or tank. The Yocan Verve encloses the cartridge instead of exposing it.

FAQ's

The Yocan Uni Pro 510 Thread Battery powers 510-threaded cartridges. It supplies the battery only, so the cartridge and its contents are separate. The Yocan Uni Pro 510 Thread Battery is not a tank or pod system and cannot be filled with e-liquid directly. It is designed to hold and fire a pre-filled or refillable 510 cartridge.

The Yocan Uni Pro 510 Thread Battery carries a 650mAh cell, which is large for a cartridge battery of this format. That capacity typically covers one to two days of moderate use. The Yocan Uni Pro 510 Thread Battery shows charge level on its display, so you can judge remaining runtime rather than guessing from performance.

The Yocan Uni Pro 510 Thread Battery adjusts from 2.0V to 4.2V in precise 0.1V increments using the front and side buttons. That is far finer control than the three-step batteries common at this price. The Yocan Uni Pro 510 Thread Battery lets you dial in the exact voltage a given cartridge runs best at rather than picking a preset.

The Yocan Uni Pro 510 Thread Battery uses an adjustable mechanism that changes both the width and the height of the cartridge housing. That lets it enclose cartridges of varying diameter and length rather than leaving them exposed. Adjusting the Yocan Uni Pro 510 Thread Battery to match your cartridge protects the glass and keeps the connection seated.

The Yocan Uni Pro 510 Thread Battery carries short-circuit protection and displays a warning when the attached atomizer resistance falls too low, which is the usual sign of a faulty cartridge. Yocan does not publish the threshold. It also locks against accidental firing. If the Yocan Uni Pro 510 Thread Battery shows that warning, replace the cartridge rather than continuing to fire it.

The Yocan Uni Pro 510 Thread Battery adds a larger 650mAh cell, a display and 0.1V voltage steps over the original Uni, which uses a simpler dial. The adjustable housing carries over. For anyone switching between cartridges with different ideal voltages, the Yocan Uni Pro 510 Thread Battery gives control the original model cannot match.

Start the Yocan Uni Pro 510 Thread Battery near the low end of its range with an unfamiliar cartridge and raise it in 0.1V steps until vapor is satisfying without harshness. Running too high scorches the cartridge coil and wastes material. The fine increments on the Yocan Uni Pro 510 Thread Battery make this easier than on a battery with three fixed levels.

No. Black Note e-liquids are naturally extracted tobacco e-liquids made for refillable pod systems and tanks. The Yocan Uni Pro 510 Thread Battery is a cartridge battery with no tank or reservoir of its own, so there is nowhere to add e-liquid. To vape Black Note e-liquid, use a refillable pod system or tank instead.

Yes. The Yocan Uni Pro 510 Thread Battery is hardware, and California’s restrictions on flavored vapor products apply to e-liquid rather than devices, so the Yocan Uni Pro 510 Thread Battery ships to California addresses. Orders require age verification at checkout and an adult signature on delivery under the PACT Act. Local city and county rules can still apply.

The Yocan Uni Pro 510 Thread Battery works well for a first battery because the display removes guesswork and the adjustable housing fits most cartridges without extra parts. The 0.1V steps look complex but can simply be left at one setting. Anyone starting with the Yocan Uni Pro 510 Thread Battery should begin low and raise voltage gradually.

    works good, great for the price

    for the price I'm very happy with this. had it for 10 months and no problems or complaints. maybe wish there wasn't a separate small part that screws onto the bottom of the cart, which can be lost or forgotten, but that's a minor inconvenience.
