510 Thread Battery, 350 mAh

Description

Hardware, and nothing else. This 510 thread battery holds 350 milliamp hours, has three voltage settings and charges over USB-C. There are no cannabinoids in it, nothing to assay and no certificate of analysis to publish, which is worth stating plainly on a site where every other listing carries one. What it does is screw onto the cartridges sold on the same shelf.

Specifications

Capacity, voltage range, thread type and charging port. Those four figures are the whole specification of a device like this, and they are the ones most listings leave out.

• 510 thread battery: 350 mAh capacity, three voltage settings
• Thread: 510, the standard cartridge fitting
• Charging: USB-C, cable not included
• Cannabinoid content: none, since this is hardware
• Certificate of analysis: not applicable, and we do not pretend otherwise
• Price: $15, and there is no per milligram figure to print

Why voltage settings matter more than capacity

Three hundred and fifty milliamp hours is a day or two of normal use and it is not the interesting number. Voltage is. A thick unflavoured distillate at 1,000 mg per millilitre needs the lowest setting or it scorches, and a thinner flavoured cart at 400 mg can take the middle one without tasting burnt. Running any cart on the top setting will cook the oil and the taste tells you within two draws. A 510 thread battery with one fixed voltage is cheaper and this is the reason we do not stock one.

What the 510 thread battery standard actually means

Five ten is a thread pitch, not a brand, and it has been the de facto standard for cartridges for years. Any cart in the cartridge range screws onto this 510 thread battery, and so will most carts bought elsewhere. Intake hole size and coil resistance in ohms are published for every cartridge here precisely so a pairing can be made deliberately rather than by trial. A badly matched pair burns oil, which wastes the expensive half of the combination.

What is published on the hardware side

More than on most of the catalogue, and it is not reassuring reading. Published analytical work on vaporiser hardware has measured metal transfer from coils and housings into aerosol, with lead, nickel and chromium among the elements found, and the amounts varying by device, coil material and the voltage it is run at. That is a description of what laboratory studies have measured in hardware generally rather than a statement about this unit, which has not itself been through that testing. Our cartridges carry a heavy metals panel on every batch, which covers the oil. The regulator’s framework for electronic nicotine and cannabinoid delivery devices sits with the Food and Drug Administration.

What fifteen dollars buys, and what it does not

It buys a cell, a board with three voltage steps, a button and a USB-C port. It does not buy variable wattage, a screen, a preheat cycle or airflow adjustment, and none of those are necessary for a cartridge. Spending forty dollars on a 510 thread battery gets you a larger cell and a display; spending eight gets you one fixed voltage and a micro USB port that will fail. Fifteen is where the useful features stop and the ornamental ones begin, which is why this is the only battery on the shelf besides the older model.

Looking after it

Charge it on the supplied standard rather than a fast charger, keep the threads clean, and wipe the seat if a cart has leaked into it, because dried distillate in the connection is the usual cause of a battery that appears dead. A 510 thread battery is also the one item here that will outlast everything bought alongside it, so it is worth the fifteen dollars once rather than a disposable repeatedly. Sold to adults of legal age only.

No lab report is linked from this page, because there is nothing in a 510 thread battery to test. The certificates on this site cover the oil in the cartridges, and they are filed by batch number on the lab results page.
