Bontrager Dual Charger Floor Pump
We engineered the Bontrager Dual Charger Floor Pump to eliminate the frustration of adaptor juggling and valve switching. The twin-piston design delivers smooth, efficient inflation whether you’re running Presta road wheels or Schrader mountain tires.
Our oversized steel barrel moves high air volume with each stroke, while the integrated pressure gauge provides accurate readings up to 160 PSI. The wide, stable base keeps the pump planted during aggressive inflation sessions, and the extra-long reinforced hose reaches both wheels without repositioning the pump. Every Dual Charger leaves our facility with a genuine Bontrager quality seal — the same precision engineering we build into every component across our <a href=”/bike-pumps/”>bike pump collection</a>.
What makes the Dual Charger different
Twin-piston technology and barrel construction
The Dual Charger’s defining innovation is our twin-piston internal charging system. Unlike traditional single-chamber pumps that require manual valve switching or separate adaptors, our design routes airflow through dedicated chambers matched to each valve standard.
The oversized steel barrel measures 2.8 inches in diameter — substantially larger than compact floor pumps — which moves significant air volume per stroke. We built the barrel from cold-drawn seamless steel tubing with internal honing for friction-free piston travel. The composite matrix handle features ergonomic contouring and stays cool even during extended inflation sessions. Our quality control inspectors pressure-test every barrel to 200 PSI before final assembly.
TwinHead chuck system and hose design
Universal valve compatibility
We designed the TwinHead chuck to eliminate the fumbling and air loss common with threaded Presta adaptors. The dual-port head features spring-loaded jaws that lock securely onto both Presta and Schrader stems — simply press the appropriate side onto your valve and flip the locking lever.
The 48-inch braided reinforced hose gives you reach to both wheels without dragging the pump across your garage. We sheath the hose in abrasion-resistant nylon and terminate both ends with forged brass fittings. The swivel connection at the chuck prevents hose twist during inflation, and the base-mounted hose clip keeps everything organized between uses.
Gauge accuracy and pressure monitoring
Our integrated 3-inch analog gauge delivers accurate pressure readings critical for optimal tire performance. The dual-scale face displays both PSI (0-160) and BAR (0-11) with clear numeric increments and a high-visibility needle.
We calibrate every gauge against NIST-traceable reference standards before pump assembly. The gauge mechanism is isolated from the barrel’s internal pressure surges through a dampening chamber, which extends accuracy over thousands of inflation cycles. The angled gauge mounting positions the face for easy reading whether you’re standing or kneeling.

Dual Charger Floor Pump questions answered
No adaptors are needed with the Dual Charger. The TwinHead chuck features dual ports that accommodate both Presta and Schrader valves natively.
Simply press the appropriate side of the chuck onto your valve stem and flip the locking lever to secure it. The twin-piston internal design routes airflow through dedicated chambers matched to each valve standard, eliminating manual switching or threaded adaptors entirely.
The Dual Charger is rated to 160 PSI maximum pressure, which covers the full range of road, gravel, mountain, and touring bike tire pressures. The integrated analog gauge displays both PSI and BAR scales with clear numeric increments.
We pressure-test every barrel assembly to 200 PSI during quality control to ensure reliable performance across the pump’s entire operating range. The oversized steel barrel and twin-piston design maintain smooth operation even at high pressures.
The reinforced braided hose measures 48 inches from base connection to chuck, which provides reach to both wheels on most bike stands without repositioning the pump. We terminate the hose with forged brass fittings at both ends.
The chuck connection features a full 360-degree swivel mechanism that prevents hose twist during inflation. This swivel design eliminates the binding and wear common with fixed-connection hoses, extending the hose’s service life significantly.
The Dual Charger functions as a standard high-volume floor pump and does not include an integrated air chamber for tubeless bead seating. For tubeless applications requiring rapid high-volume air delivery, we recommend our TLR Flash Charger Floor Pump specifically engineered for tubeless setup.
The Dual Charger works excellently for topping off tubeless tires after initial installation and for all standard tire inflation across your entire bike fleet.
The Dual Charger requires minimal maintenance under normal use. Periodically wipe down the steel barrel with a clean dry cloth to remove dust and moisture, and store the pump in a dry location.
Check the chuck jaws every few months to ensure they lock securely onto valve stems — any debris can be cleared with compressed air. The internal piston seals are factory-lubricated and typically require no service. If you experience reduced pressure or air leakage after extended use, contact Bontrager customer service for seal replacement options.
Yes, the integrated analog gauge is a serviceable component. Bontrager stocks replacement gauge assemblies that thread into the barrel mounting port.
We calibrate every replacement gauge against the same NIST-traceable reference standards used in production. Gauge replacement is straightforward for home mechanics with basic tools, and we provide illustrated instructions with replacement gauge shipments. Contact our customer service team to order replacement gauges by referencing your pump’s SKU number.
Every Dual Charger ships with a ball inflation needle and a Presta valve adapter stored in the magnetic dock on the base. We also include a suspension pump adapter for riders maintaining air-sprung forks and shocks.
The magnetic retention system keeps these accessories secure during storage but releases easily when needed. Additional or replacement attachments are available separately through Bontrager dealers if accessories are lost or if you need specialized inflation adapters.
