Who it fits
Good fit for
You should consider this cable if you own a Goal Zero Yeti 1250 and need to double your storage capacity. It is also suitable for users with a Sherpa 100ac who require an 8 mm connection. If your solar setup needs a 30-foot reach between panels or devices, this extension provides the necessary distance. The high current rating ensures efficient power transfer for compatible high-power units. It is ideal for campers who want to expand their battery bank without buying a larger single unit.
Who should skip it
Look for another option if your devices use different connector types, such as MC4 or Anderson plugs. This cable only works with 8 mm SB175 ports, so it is not universal. If you need a shorter or longer length than 30 feet, this specific model will not fit your setup. It is also not suitable for devices that exceed the 175A limit. Users requiring Bluetooth connectivity or app control for power management will find this passive cable lacks those digital features entirely.
Verdict: This extension cable is a practical solution for expanding capacity between compatible Goal Zero devices. It offers the necessary length and current capacity for specific high-power setups.
Key specs for this extension cable
Cable Length: 30 ft (9 m)
This length gives you flexibility in placing your solar panels away from your power station. You can position panels for optimal sun exposure without worrying about reach. It is ideal for setups where the generator sits in a sheltered area while panels remain in direct light. Check your setup distance to ensure this 30-foot span covers the gap between your devices effectively.
Connector Type: 8 mm, High Power Port SB175
The 8 mm connectors ensure a secure physical link between compatible Goal Zero devices. The High Power Port SB175 designation indicates the specific interface standard used for high-current transfer. You must verify your devices support this port type before purchasing. This connector type prevents loose connections that can lead to power loss or safety hazards during outdoor use.
Compatible Devices: Goal Zero Yeti 1250, Sherpa 100ac
This cable works specifically with the Goal Zero Yeti 1250 and Sherpa 100ac units. You can use it to link two Yeti 1250 units to expand total storage capacity. It also allows connection to the Sherpa 100ac for additional power routing. Always cross-reference your specific model numbers with this list to ensure the cable fits your existing hardware configuration properly.
Max 175A
The maximum current rating of 175 amperes defines the electrical load limit for safe operation. This high capacity supports the power demands of connected high-output devices like the Yeti 1250. Exceeding this limit can damage the cable or connected equipment. Ensure your total power draw stays within this threshold to maintain system stability and safety during extended off-grid usage.
Design and build specs
The listing describes the cable as black and notes a weight of 12 ounces. This light mass makes it easy to carry during camping trips or tailgate events. You can pack it in a side pocket without adding bulk to your gear. The compact dimensions of 13 by 8 by 3 inches allow for tidy storage in a backpack or gear box.
According to the listing, the cable features High Power Port SB175 connectors on both the input and output ends. This specific design ensures a secure link between compatible devices like the Goal Zero Yeti 1250 and Sherpa 100ac. The 8 mm connector type is standard for these units, reducing the risk of loose connections during transport.
The 30-foot length provides ample reach for positioning solar panels away from your power station. You can place panels in direct sunlight while keeping the unit in shade or under a tent. This setup helps manage heat and extends battery life. The black finish blends with outdoor equipment, though it may show dirt after use. The simple layout requires no complex setup or additional tools. You just plug it in and start charging. This straightforward design suits users who value reliability over extra features.
Setup And Everyday Use
You connect this cable by aligning the 8 mm connectors on both ends. The listing specifies High Power Port SB175 inputs and outputs for both sides. This means you plug one end into a compatible device and the other into another compatible unit. You can link two Goal Zero Yeti 1250 units together to expand your total capacity. The cable also works with the Sherpa 100ac, giving you options for different gear combinations. The maximum current rating is 175A, which supports high-power solar charging tasks. When setting up, you simply route the 30-foot cable between your power stations or panels. The black color helps it blend into outdoor environments. Since it weighs only 12 ounces, you can easily store it in your gear bag. Daily use involves checking that the connectors are fully seated to ensure a stable connection. You should avoid sharp bends that might stress the 8 mm ports. The 30-foot length allows you to place your power station away from noise or heat sources while keeping it close enough to your solar array. This distance provides flexibility for optimal sun exposure. You do not need additional adapters or complex wiring. The setup is straightforward because both ends use the same connector type. You can quickly disconnect and reconnect the cable as your power needs change. The cable supports solar charging, so you can integrate it into your existing solar workflow without extra components. This simplicity makes it reliable for regular use in the field.
Before You Buy This Cable
You should verify that your power station supports the High Power Port SB175 standard. This cable connects compatible devices like the Goal Zero Yeti 1250 and Sherpa 100ac. If your unit uses different ports, this extension will not fit. You may need additional adapters or a different cable entirely to bridge incompatible systems. Keep the connectors clean to ensure reliable power transfer. Store the cable in a dry place to protect the black insulation from UV damage and moisture. This accessory extends your setup flexibility but does not generate power itself. It works best when paired with solar panels or another battery unit. Consider how far you need to reach. Thirty feet offers good range, but check your specific layout. This cable is a simple link in a larger chain. It complements other portable power stations by allowing you to expand capacity or position panels optimally. Ensure all connected devices are turned off before plugging or unplugging to prevent arcing.
Check before you buy
- Confirm your device uses the High Power Port SB175 standard
- Check if your power station is a Yeti 1250 or Sherpa 100ac
- Verify you have compatible solar panels or another battery unit
- Ensure you have space for the 30-foot cable length
- Inspect connectors for dirt or corrosion before first use
