E-Tank Cart is a wheeled carrier designed to transport E-size oxygen cylinders safely and conveniently within the home or during patient transport. It keeps the cylinder upright and secure, preventing tipping, and typically features a small storage area for accessories such as the regulator, cannula, and wrench.

E-carts are a key component of portable home oxygen setups and are included in standard portable O2 packages. OxyCare supplies E-carts as part of complete portable oxygen configurations and as standalone items.
