BEST POWER

Power Your Aircraft. Protect Your Avionics.

Purpose-built ground power for the work you do before the propeller turns—and dependable starting power when it is time to fly.

The Right Kind of Power for the Job

Ground power and starting power solve different problems. Best Power keeps those jobs clear so you can choose the system your aircraft and workflow actually require.

Continuous Ground Power

Stable external power for avionics work, diagnostics, software updates, familiarization, and maintenance—without drawing down the aircraft battery.

High-Current Starting Power

Portable 13 and 28-volt starting power engineered to deliver the current needed for dependable engine starts.

CONTINUOUS AIRCRAFT POWER

Three Outputs. One Purpose-Built Platform.

Choose the output that fits your aircraft and workload. Each compact Best Power supply is made to support ground operations—not engine starting or battery charging.

Portable continuous power for compatible 12-volt aircraft. It keeps avionics and aircraft systems supported during ground work while helping preserve the aircraft battery for flight.

  • 27 amps of continuous ground power
  • Compact, protected portable format
  • Ideal for avionics, diagnostics, and maintenance workflows
EFFICIENT EVERYDAY SUPPORT

28V / 27A Power Supply

A portable 28-volt supply for routine ground operations that do not require the BP56’s higher output. The integrated display keeps voltage, watts, amps, and watt-hours visible at a glance.

  • 27 amps of continuous power at 28 volts
  • 100–240 VAC input, 20 amp
  • 19 × 14 × 7 inches; 28 pounds with cords and tools
  • Internal cord and tool storage
MORE POWER FOR DEMANDING GROUND WORK

BP56 — 28V / 56A

The BP56 doubles the continuous output of the 27-amp model for aircraft and workflows with greater electrical demand. It delivers stable 28.6-volt power in the same compact, self-contained format.

  • 56 amps of continuous power at 28.6 volts
  • 100–240 VAC input, 20 amp
  • Digital voltage, watts, amps, and watt-hour display
  • 19 × 14 × 7 inches; 28 pounds with cords and tools
HIGH-CURRENT STARTING POWER

Ready When It Is Time to Start

Best Power Carts deliver portable starting current at both 13 and 26 volts, with two output levels to match the aircraft and the demands of the operation.

PORTABLE STARTING POWER

Best Power Cart 800

Dependable high-current starting power in a portable rolling package. The Cart 800 gives owner-operators a purpose-built starting system without confusing it with continuous avionics power.

  • 13 VDC and 28 VDC output

  • Bluetooth-capable monitoring for battery health, use cycles, and amperage draw
MAXIMUM PORTABLE STARTING OUTPUT

Best Power Cart 1200

For more demanding starts, the Cart 1200 increases available cranking power while retaining the portable dual-voltage Best Power Cart format.

  • 1,200 cold-cranking amps

  • 13 VDC and 28 VDC output

  • Bluetooth-capable monitoring for battery health, use cycles, and amperage draw
