What is the difference between MC4 and DC8020?

DC8020 is the 8 mm barrel input Jackery uses. Check polarity on any third-party cable, because barrel connectors offer no keying against a reversed centre pin. MC4 is the locking connector most solar panels use. In our catalogue, 2 of 7 verified stations have a DC8020 solar input.

Which gauge of MC4 to DC8020 cable should I buy?

Buy 10 AWG if you can, particularly on long runs. At 10 A over a 20 ft run, 10 AWG copper drops about 0.4 V and 14 AWG about 1.0 V. That lost voltage matters most for a single 12 V class panel near the port’s minimum voltage. The table below covers common lengths.

Voltage drop at 10 A by one-way length, standard copper resistance at 20 °C
One-way length	10 AWG	12 AWG	14 AWG
10 ft	0.20 V	0.32 V	0.51 V
20 ft	0.40 V	0.64 V	1.01 V
30 ft	0.60 V	0.95 V	1.51 V
60 ft	1.20 V	1.91 V	3.03 V
120 ft	2.40 V	3.81 V	6.06 V

Does a MC4 to DC8020 cable change the voltage limit?

No. A cable only carries the panels’ voltage, so it never protects a port. A string that breaches the station’s maximum in the cold will still breach it through any adapter. Check the string’s cold open-circuit voltage first on the pair page for your station and panel, then choose the cable.
