How Do You Use a 510 Cart? Setup, Voltage and Fixes

Quick Answer

To use a 510 cart, screw it onto a charged 510 battery until it is snug, turn the battery on, then press the button (or just inhale on a draw-activated battery) and pull slowly for two to three seconds. Keep the voltage low, start with one small pull, and wait a few minutes before the next.

What Is a 510 Cart?

A 510 cart is a small cartridge of oil with a heating coil inside. "510" is just the thread size, the same screw fit on most vape batteries, so one battery works with almost any cart. The battery heats the coil, the coil turns the oil into vapour, and you breathe it in through the mouthpiece.

Our 510 carts are THC distillate blended with terpenes for each flavour, filled in-house, and they fit any standard 510 battery. If you want to know how distillate compares with live resin and rosin, we broke it down in our distillate vs live resin vs live rosin guide.

How to Use a 510 Cart in 4 Steps

  1. Charge the battery. Plug it in until the light says it is full. A half-dead battery is the most common reason for a weak hit.
  2. Screw the cart on. Turn it clockwise until it is snug, and stop there. Cranking it down can push the centre pin in and stop it from firing.
  3. Turn it on. Many push-button batteries switch on with five quick clicks, and some have no button at all and fire when you inhale. Every battery is a little different, so check the card that came with yours.
  4. Pull slow. Hold the button (or just inhale, on a draw-activated battery) and pull gently for two to three seconds. Then stop and give it a few minutes before deciding on another.

Need a battery? The 510 battery comes in three styles: a Slim 350 mAh with no display, a Slim 220 mAh with a display, and a bigger XL 400 mAh with a display.

Low And Slow

What Voltage Should You Use?

Low to medium. Our cart pages, like the Orange Creamsicle cart, recommend keeping it between 2.5 and 3.3V. Lower settings keep the flavour bright and make the oil last longer. Crank it up and you get a hotter pull, a burnt taste and a cart that runs out sooner.

If your battery has no voltage control, that is fine. Just take shorter, slower pulls.

How Long Does a 510 Cart Last?

It depends on how you pull. Short, gentle pulls stretch a 1ml cart a long way; long, hot ones burn through it. Because the oil is mostly THC, a puff or two goes further than you would expect, so go easy at first and let the cart last.

Troubleshooting

Why Is My 510 Cart Not Hitting?

Work down this list. It fixes most dead carts in a minute or two.

  • Check the charge. Plug the battery in and try again.
  • Check the fit. Unscrew the cart and screw it back on until snug. A loose or crooked cart is a common cause.
  • Wipe the contacts. Dab a cotton swab with a little rubbing alcohol and clean the threads and the centre pin on both the battery and the cart. Let it dry fully.
  • Check the airflow. Pull on the mouthpiece with the battery off. It should feel open, not blocked.
  • Try another battery. If the cart works on a second battery, the first battery is the problem.

Why Does My Cart Taste Burnt, Clog or Leak?

Burnt taste

Nearly always, the voltage is too high or the pulls are too long. Turn it down to the 2.5 to 3.3V range, take shorter pulls and give it a few minutes between hits. A cart that is almost empty can also taste burnt, because there is not enough oil left to cool the coil.

Clogged cart

Thick oil and hard, fast pulls cause clogs. Hold the cart in your hand or a warm pocket for a minute so the oil thins out, take a few slow pulls without pressing the button to clear the airway, and keep the cart upright so the oil sits over the coil.

Leaking cart

Usually it is heat or pressure. Do not leave a cart in a hot car, store it upright, and do not over-tighten it on the battery. If oil gets on the threads, wipe it off with a dry cloth or an alcohol swab before you use it.

Carts Or Pens

Would a Disposable Pen Be Easier?

If you want zero setup, a 2g disposable pen has the battery built in: nothing to screw on, and it fires when you inhale. If you already own a 510 battery, a cart is the lower-cost way to try more flavours. New to concentrates in general? Our guide to what dabs are and how to dab covers rigs and pens too.

510 Cart FAQs

Does any 510 battery fit any 510 cart?

Any standard 510-thread cart screws onto any standard 510-thread battery. Ours are standard 510 thread, so they fit the battery you already have.

How do you charge a 510 battery?

Use the USB cable that came with it. Most batteries have a light that changes colour or stops blinking when the charge is full; check the card that came with yours for its exact signals.

Why is my 510 battery blinking?

Blinking usually means a low charge, a bad connection between the cart and the battery, or a safety cut-off after a very long pull. Charge it, clean the contacts, re-seat the cart and try again. If it keeps blinking, check the guide for your model.

How many volts should a 510 cart run at?

Low to medium. Our cart pages recommend 2.5 to 3.3V. Higher settings make bigger, hotter clouds but burn the flavour and use up the oil faster.

Can you refill a 510 cart?

Most carts are made to be used once, as filled. We do not sell refill kits and recommend using our carts the way they come.
