MC4 to DC7909 cable
It joins a panel with MC4 plugs to a station with a DC7909 solar port. 5 of the stations we chart have that port.
By the Power Station Chart team, from maker pages. Last reviewed October 31, 2026.
Bluetti sells one for the EB3A. Jackery sells adapters between DC7909 and DC8020 instead.
The two plugs
| MC4 | The standard solar panel plug. Almost every rigid panel and many portable panels end in MC4 leads. Makers rate these up to 30 A. |
|---|---|
| DC7909 | A round barrel plug, 7.9 mm across with a 0.9 mm pin. It looks almost the same as DC8020, but the two are not interchangeable. Makers rate these up to 14 A. |

A cable fixes the plug, not the voltage. Check the panel against the station's limits before you connect anything. MC4 connectors explained.
FAQ
What is a DC7909 plug?
It is a round barrel plug, 7.9 mm across with a 0.9 mm pin, and it is listed up to 14 A. It looks almost the same as DC8020, but the two are not interchangeable. Five stations use DC7909 for solar input.
Who sells an MC4 to DC7909 cable?
Bluetti sells a Solar Charging Cable (MC4 to DC7909) for the B80 or EB3A, and its listing prints no length, gauge or rating. Anker takes a different route for the PS100, which has a DC7909 solar port: its guide pairs a Solar to XT-60 cable with an XT-60 to DC7909 cable.
Is DC7909 the same as the Jackery plug?
No. Jackery's current panels and newer stations use DC8020, a close cousin that looks almost identical. Jackery sells adapters between DC7909 and DC8020 rather than a plain MC4 cable.
