Looks like I’m a little late to the party since you’ve already bought a charger. But for the benefit of others who might have the same question, here’s what I’ve been using for the last year and half that I’ve owned my EQ800.
For charging at home, I hook the provided Minelab charging cable to a Legrand combination standard/USB-A wall outlet courtesy of Lowe’s:

When away from home but charging indoors, I use an old Anker brand wall USB charger that I had laying around the house (I don’t think they make this particular variety anymore, but anything from Anker is quality stuff):

My car is old, so I don’t have built in USB ports. I have a cigarette lighter style power inverter with USB-A ports and a standard outlet that lives in the car for device charging:

For charging in the field if necessary, I have a Anker PowerCore brick available. Its specs are a bit worn off in the pic, but the brick stores 26800 mAh, which was enough to charge an iPad and my cell phone multiple times. I’ve only used it a couple times to give the Equinox a partial charge, so I don’t know for sure how many times it could charge the detector, but the partial charges didn’t put much of a dent in the brick’s charge:
