ZkeeShop12V DC8MM Car Charger Cable 15A,DC7909 7.9 x 5.5mm Car Cigarette Lighter Cable Compatible with Bluetti EB3A/EB70 Portable Power Station,Camera,Laptop(1.5M) 4.9FT

I’m using for my S10 CpapWorks as it should

When connected to 13.2v battery, the best I've been able charge a eb3a is around 35 watts or 3 amps. I suspect the wire gauge is too small or there must be bad connections at the terminals. I will post follow up after more testing and inspection but for now I suggest you keep looking. Follow Up...it turns out that the dc source I was using was just over 12v so not enough voltage potential to push more than 3 amps to the eb3a I was charging. The listed wire size equate's to 17awg so it wouldn't be rated to carry much over 3 amps anyway. Bottom line is you need a higher dc voltage than 12v to charge a eb3a if you need to charge at much more than 40 watts...not really the cables fault.

I needed a much longer cable to run from the dash to my Bluetti solar generator in the back of my van. This one is perfect. Five feet of cable just what I needed. It seems like decent quality and it's working well. It was a great price so there's nothing to complain about.

Works immediately in my vehicle and is perfect for long road trips and camping. Extremely happy with this product and it was exactly what I was looking for!!

Will not charge my bluetti
