Tonton8mm DC Extension Cable 3M(10ft) for Jackery Explorer 1000 V2/500/300/240 Portable Power Station, DC7909 to DC8020 Adapter Solar Cable, Compatible with BLUETTI Power Station EB3A/EB70/EB70S

I have the Jackery Extension cable too but it was just too short, this is excellent quality and work just as it should, nice thick outer casing so should last for long time.

This is a very useful solar power connector cable that is three metres long with two output connectors possible. By using a 7.9mm and an 8mm adapter option to convert the connection type it allows for multiple uses where the various power units have either one or the other input connection type. With the three metre length of cable it also allows for a greater distance between the two power input/output devices. A good addition to an existing solar power connection to widen its use with many other power banks etc.

This extension cable's material is thick and dependable, so it's not easily torn . The design is practical. And since the insulator is thick you can use it outdoors but with your discretion.

This product was supplied for testing and reviews through the Amazon Vine Program.The Tonton DC 8mm Extension Cable is actually a DC7909 extension cable with a DC7909 to DC8020 adapter at the male end. Many portable power stations use these types of plugs to connect to solar panels. When I originally tested this cable with a meter there was continuity, but when plugged into a Bluetti power station there was no connection. I discovered that the manufacturer has added an extra portion to the molding at the plug end so that the adapter would fit, but this prevents the plug from making proper contact. I carefully cut that extra portion off the plastic and the cable now works perfectly. it was a very easy modification, but the consumer should not have to do this. Someone should check to see if the product will actually function as intended. This is a shame because the cable is really well made and the plugs and wire are of very good quality.Unfortunately, I cannot recommend this product because it can't fulfill it's intended function.My testing and analysis is based on one individual sample. If the product meets the manufacturer’s performance claims and does it in a safe manner, than I give it 5 stars. Prices on similar items are compared when testing to determine whether the product is good value.

I just purchased a Jackery solar generator but wanted to add an extension of my solar panels to my generator.This cable is heavy, high quality, and well worth the purchase.I hooked it up and I was off to the races! Worked right out of th ebox!Add 10ft to your solar panel setup to ensure that you can keep your generator dry and out of the sun.
