Chunzehui F-1011 6-Position Power Pole Block
The Chunzehui F-1011 is a compact 6-position distribution block rated at 45A per port, suitable for DC power systems that need multiple outputs from a single source. It supports compatible 15A, 30A, or 45A power pole connectors and a maximum of 60VDC. This block is best for users who require straightforward, high-current distribution with robust port compatibility.
Who it’s best for: hobbyists and field users who want a straightforward, high-load distribution with flexible connector compatibility. Why selected: it provides six strong outputs and clear power handling limits, making it easy to size cables and fuses for a small rig.
Caution: verify that your load distribution remains within the 60VDC and 45A per-port limits to avoid overheating or connector mismatch.
GUIRUIMOON 1 In 6 Connector Power Divider
The GUIRUIMOON distribution block combines a 1-in-6 output design with a fused, aluminum alloy housing. It operates DC 0-32V with a maximum input of 40A and includes a mix of fuses (30A, 20A, 10A, 5A). The unit emphasizes mechanical durability and low idle current, ideal for compact, portable setups where weight and heat management matter.
Who it’s best for: users needing a lightweight, durable block with built-in fusing and a predictable port mix. Why selected: the varied fuse ratings help tailor protection for different devices on a single chassis.
Caution: ensure your total current draw stays within 40A and inspect fuse ratings to match your protected circuits.
FUAUJUE 1 In 6 Connector Power Divider
The FUAUJUE block is designed for 0-32VDC operation with a total 40A max input and six outputs, each with its own fuse. It features a robust aluminum alloy shell with a black oxidation finish for durability and a replaceable fuse design to lower long-term maintenance costs. This option is well-suited for RV or portable solar installations where safety and serviceability matter.
Who it’s best for: mobile or off-grid setups that value a replaceable fuse path and strong enclosure protection. Why selected: the design prioritizes safety, longevity, and ease of fuse replacement in the field.
Caution: confirm the fuse configuration on each output matches device protection requirements to prevent nuisance blows.
Chunzehui F-1005 9-Port Power Splitter
The Chunzehui F-1005 expands to nine ports with a 40A total current capacity. It offers a 0-32VDC operating range and a fairly compact footprint, including a power indicator LED and a fault indicator LED for each fuse. A replaceable fuse holder enhances long-term serviceability, and ATC/ATO fuses are readily available.
Who it’s best for: those needing more outputs without a large enclosure. Why selected: the combination of multiple fuses per port and indicator LEDs supports quick troubleshooting in complex rigs.
Caution: the total current must be managed carefully due to the higher port count; ensure wiring and fuses are sized appropriately for your load.
OONO 40 Amp Power Pole Splitter
This 40A distribution module provides five power pole outputs and six USB ports, combining traditional power rails with USB power. It supports 8.5–32V DC input, a maximum 40A main current, and individual output port fuses, plus USB ports offering up to 2.4A per port. It is a strong choice for mixed-device configurations where USB-powered devices are common.
Who it’s best for: users needing both DC power poles and USB outputs in one compact module. Why selected: the built-in USB ports add versatility for peripheral devices without carrying additional adapters.
Caution: USB ports share power with the DC outputs; manage device combinations to avoid exceeding the 40A main input rating.
Buying Guide
What to consider when choosing a power pole distribution block:
- Current needs: Match the total continuous load to the main input rating and the per-port fuse ratings.
- Voltage range: Ensure the device operates within the DC voltage window (commonly 0–32V or up to 60V for some units).
- Port configuration: Count outputs and verify fuse distribution aligns with your devices’ protection needs.
- Durability: Aluminum shells and oxidation finishes improve wear resistance in portable or outdoor setups.
- Ease of maintenance: Replaceable fuses and accessible fuse holders reduce upkeep time and costs.
- Integrated features: USB ports or indicators can simplify setup but may constrain overall current.

FAQ
- What is a power pole distribution block?
A distribution block splits a single power source into multiple outputs using Anderson Powerpole connectors. It provides fusing and a defined current path for each output.
- Why use fuses on each output?
Fuses protect devices from overcurrent and short circuits, helping prevent wiring damage and component failure.
- Can I mix different fuse ratings on a block?
Yes, many blocks support varied fuse ratings per port, but you must ensure the total draw does not exceed the main supply and individual port limits.
- Is aluminum better than iron for these blocks?
Aluminum enclosures are lighter and typically more resistant to corrosion and wear, which is beneficial for portable setups.
- Should I choose a block with USB ports?
USB ports are convenient for powering peripherals, but ensure the combined current remains within the main supply rating.
- How do I size cables for these blocks?
Size cables to handle the maximum current per port and the total current, with appropriate insulation and temperature ratings.
