The Kanger Protank 4 is a tall, versatile tank that can be used by any vaper regardless of whether you are a newbie or advanced. The Protank 4 is a vast improvement from the Kanger Protank 3 which was a strictly mouth-to-lung device. The Protank does not only support mouth-to-lung vaping, but you can also use it for direct lung vaping with sub ohm coils and even build your own coil.

The Kanger Protank 4 has a striking appearance with its dimensions of 65.5mm by 22mm. It is made of corrosion-resistant 304 Stainless Steel and Pyrex glass. The tank is largely made of stainless steel and has two small windows on either side to allow you check your e-liquid level.

The main selling point of the Kanger Protank 4 is that you can use different coil heads on this tank. It even comes with a rebuildable atomizer (RBA) coil deck.

The tank comes pre-installed with a 0.5 ohm stainless steel and organic cotton (SSOCC) ceramic coil. There is a 1.5 ohm SSOCC coil head in the package for mouth-to-lung vaping. The box also includes an RBA deck which comes pre-installed with dual 0.6 ohms Clapton coils that clock in at 0.3 ohms. You will also find two extra coils in the package.

The Protank 4 has a velocity style dual post. It may be difficult for beginner vapers to work with the RBA coil deck that comes with the Kanger Protank 4. This is because the deck is quite tiny and unless you are a vet you would have issues finding a way to navigate it – especially when it comes to fitting in the ends of your wicking material in the tiny reservoir holes below. It is recommended that you use high VG e-liquid brands with this tank to avoid flooding.

The 0.5 ohms ceramic coil that is fitted in the Protank 4 produces clean and cool vapor when you take a hit. However, if you prefer a warm vape with that characteristic crackling sound, it is best to use the RDA deck.

The Aspire Protank 4 has multiple airflow channels so you can bet it will chunk out massive clouds. There are two large airflow slots at the base of the tank that you can control by turning the bottom ring. There are also airflow slots under the Delrin drip tip. You can remove the drip tip that comes with the Protank 4 and fit in any standard 510 drip tip.

The tank can hold up to 5ml of e-juice. This will suffice to last most vapers for an entire day. The tank has a top side filling design, so you do not have to take the tank apart each time you want to refill the tank. To refill the tank, you need to unscrew the top cap and lift it up. Then you have to slide the cylinder beneath to reveal the side filling holes. This intricate design of the tank means it is child proof. So if you are a parent, you do not have to worry about your little ones being able to open up your tank.

At the bottom of the Aspire Protank 4, you will find a 510 connection for attaching it to your mod. The 510 connection is gold-plated to prevent any corrosion.

The Aspire Protank 4 comes in black, red, silver, and white color. You can get this tank from virtually any vaping store. It costs about $29.99 to buy it from the Vapor4Life online shop.

Overall, the Protank 4 is one of those tanks that ever vaper needs in their collection. The fact that it allows you choose between three different coil options is what makes the tank stand out from the others.
