Electrical Specifications
| Parameter | Specification |
|---|---|
| Battery Type | Rechargeable Li-Ion |
| Battery Capacity | 5000 mAh (some newer versions) / 7800 mAh (earlier European listings) |
| Charging | USB |
| Input Voltage | 5V USB |

Engineering Assessment
This is one of the highest-quality portable fueling pumps available for large RC gasoline aircraft. Its aluminium construction, reversible operation, integrated rechargeable battery, and high flow rate make it well suited for engines in the 30 cc to 300 cc+ range.
The pump is optimized for moving fuel quickly rather than generating high pressure, which is ideal for RC fueling systems using silicone or Tygon tubing and standard tank fittings. Because DLE does not publish an official pressure rating, it is best to describe it by its flow capacity (1.5–2.0 L/min) and intended use as a high-flow, low-pressure fuel transfer pump, rather than quoting a specific pressure specification.
