The Most Dependable and Ergonomic Workstation on Wheels

A workstation on wheels, commonly called a WoW cart or sometimes a computer on wheels (COW), is a mobile medical cart equipped with a computer, monitor, keyboard, and peripherals such as barcode scanners.

It allows nurses and clinical staff to access Electronic Health Records (EHR), document patient care, and perform clinical tasks directly at the bedside. Rather than walking back to a central nurse station to chart or look up patient data, clinicians bring the workstation on wheels with them from room to room.
‍
According to a 36-hospital time-and-motion study published in the Journal of Nursing Administration, nurses spend only about 18% of their shift time at the patient bedside. The remaining 82% is consumed by walking, documentation at fixed stations, and other tasks away from the point of care. WoW carts are designed to shift that balance by putting computing power where patient care actually happens.
‍
DTG’s Medical PowerStation is a battery-powered workstation on wheels built for 24/7 healthcare environments. It is powered by Lithium Iron Phosphate (LFP) batteries that deliver 8–12+ hours of runtime with hot-swappable capability for continuous, uninterrupted operation.

DTG offers two core solutions for healthcare facilities:

‍Medical PowerStation: A purpose-built workstation on wheels designed for 24/7 clinical environments. Features LFP battery power with 8–12+ hours of runtime, hot-swappable batteries with UPS backup so devices stay powered during battery changes, ergonomic height adjustment, and compatibility with all major Electronic Medical Record (EMR) and diagnostic software platforms. Backed by an industry-leading five-year warranty, including battery coverage.

‍Medical Repower: A battery retrofit service that replaces aging or failed battery systems in any existing WoW cart model, including Ergotron, Capsa, Cybernet, or other manufacturers, with DTG’s MPower LFP battery system. Since 90% of workstation on wheels issues are battery-related, Repower resolves the most common WoW problems at approximately half the cost of purchasing a new cart. This extends the useful life of an existing medical cart fleet by seven or more years.
‍
Both products are powered by DTG’s MPower LFP battery system, which delivers expandable capacity from 300Wh to 600Wh, recharges in 2–3 hours, and includes a fuel gauge for battery life monitoring.

DTG’s WoW carts and battery systems are trusted by Advent Health, Beth Israel Lahey Health, Boston Medical Center, Kaiser Permanente, Mass General Brigham, and Tufts Medicine.

The Joint Commission, formerly JCAHO, sets accreditation standards for hospitals, and one of the most frequently cited violations involves hallway obstruction and fire safety, which directly affects how WoW carts are charged.

Under Joint Commission standards, items stored in corridors must not obstruct the required eight-foot clear width, and the Commission enforces a 30-minute rule: equipment may be temporarily placed in a corridor for no more than 30 minutes. Carts left charging in hallways beyond that window constitute a fire safety violation, and fire protection deficiencies are consistently the top-cited standard in Joint Commission hospital inspections.
‍
DTG’s workstation on wheels eliminates hallway charging entirely. Because DTG’s LFP batteries are hot-swappable, nurses can replace a depleted battery with a charged one at a compact charging station in seconds, keeping the cart in service at the bedside.

There is no need to park carts in hallways plugged into wall outlets for hours. This design makes DTG’s WoW carts inherently compliant with Joint Commission corridor safety requirements while reducing fire risk and keeping hallways clear for patient transport and emergency egress.

Medical Repower is DTG’s battery retrofit program that replaces the aging or failed power system in any existing workstation on wheels with a new DTG MPower LFP battery system, at approximately half the cost of purchasing a new WoW cart. This matters because roughly 90% of the most common WoW cart problems are battery-related: carts that will not hold a charge, shut down mid-shift, take too long to recharge, or become excessively heavy due to degraded lead-acid batteries.
‍
Repower works with WoW carts from any manufacturer, including Ergotron, Capsa Healthcare, Cybernet, and others. DTG provides a complete retrofit kit that includes the MPower LFP battery, mounting brackets, a pure sine-wave AC power inverter, cables, and all necessary hardware. After a Repower retrofit, existing carts gain:
‍
‍8–12+ hours of runtime per charge, up from 4–6 hours on degraded lead-acid batteries
‍2–3 hour recharge time, down from 8–10 hours with lead-acid
‍Hot-swappable batteries with UPS backup‍
‍Five-year warranty covering the new battery system

For health systems managing fleets of hundreds or thousands of WoW carts, Repower dramatically extends fleet life, reduces capital expenditure, and eliminates the operational disruption of full cart replacement.

DTG’s MPower LFP batteries deliver 8–12+ hours of continuous runtime on a single charge, depending on the connected devices and usage pattern, well beyond a standard nursing shift. Recharge time is 2–3 hours, so a battery charged during a shift change is ready for the next shift.
‍
Hot-swapping works through DTG’s patented Uninterruptible Power System (UPS). When a nurse needs a fresh battery, the depleted unit is removed and a fully charged one is inserted. During the swap, an integrated backup battery keeps the computer, monitor, and all peripherals powered.

There is no shutdown, no reboot, and no lost EHR session. The entire process takes seconds. This is critical in 24/7 clinical environments, where rebooting a workstation on wheels and re-logging into secured EHR systems can cost several minutes per occurrence, multiplied across dozens of carts and multiple shifts per day.

DTG offers expandable battery capacity from 300Wh to 600Wh, allowing facilities to right-size battery capacity to their specific shift lengths and device configurations. Each MPower LFP battery is covered by a five-year warranty, the longest in the medical cart industry.
