Hoeine MC4 to 8mm DC Adapter Cable for Jackery – 20FT Solar Extension, 12/14AWG Weather-Resistant

Hoeine 20FT MC4 to DC 8mm adapter cable connects solar panels with Jackery and other portable power stations for safer, more efficient charging.

This 20-foot solar extension from Hoeine converts standard MC4 solar outputs to an 8mm DC jack compatible with Jackery Explorer models and many other power stations. Built with mixed 12AWG/14AWG conductors, sealed connectors and a weather-resistant jacket, it extends panel placement options so you can keep your power station shaded while panels stay in direct sunlight.

How does this adapter improve charging with a Jackery power station?

The adapter eliminates the need for awkward positioning by converting MC4 solar leads to an 8mm DC input that Jackery units accept. Thicker copper conductors reduce voltage drop across the 20-foot run, preserving more of your panel’s power before it reaches the battery.

• 20-foot length for flexible panel placement and sun tracking
• 12AWG + 14AWG wiring to minimize power loss
• MC4-to-DC7909/DC8020 male conversion for Jackery compatibility
• Sealed MC4 connectors prevent moisture intrusion

Is the cable durable enough for outdoor solar setups?

Yes — Hoeine uses tinned copper conductors and a robust PVC jacket engineered to resist oxidation, temperature swings and routine outdoor exposure. The cable and connectors are tested for safe DC operation and designed to withstand sun and rain during normal use.

• Tinned copper for corrosion resistance and reliable conductivity
• PVC outer jacket rated for -15°C to 80°C (5℉–176℉)
• Connector testing up to 300V DC and rated current ≤20A
• Sealed MC4 ends to limit moisture and dirt ingress

Which power stations and panels work with this adapter?

The Hoeine MC4-to-8mm adapter was made for a broad range of portable power stations that accept 8mm DC inputs, including many Jackery Explorer models. It also works with competitive units from BLUETTI, Goal Zero and Anker when those devices support the same DC connector type and input specs.

• Compatible with Jackery Explorer series (160, 240, 500, 1000, etc.)
• Works with BLUETTI, Goal Zero Yeti and Anker models supporting 8mm DC
• Connects to typical MC4-equipped solar panels and arrays
• Useful for panels with MC4 outputs needing conversion to DC7909/DC8020

How does this cable make setting up solar more convenient?

The 20FT length and flexible gauge combination let you situate panels for maximum irradiance while keeping the power station in a dry, secure spot. Quick MC4 mating and a direct male DC plug simplify hookups so you can deploy or move the system faster without extra adapters.

• Long reach enables shaded placement of the power station
• Easy plug-and-play MC4 connectors for fast panel connection
• Male DC plug fits common 8mm jack inputs directly
• Optimized for everyday outdoor use and frequent repositioning

Who is this for? The Hoeine 20FT MC4 to DC 8mm adapter is aimed at outdoor enthusiasts, RV owners, overlanders and homeowners who use portable power stations and solar panels together. If you need a weather-resistant, low-loss extension to convert MC4 outputs to an 8mm DC input — especially for Jackery and similar units — this cable simplifies installation while preserving charging efficiency.
