No. Ego is a 510-threaded battery, not a 510 battery. It should use its own charger if you want it to charge in a reasonable amount of time. And its fat metal collar will prevent it from fitting in many 510 charging cables. In addition SOME 510 chargers can kill it (FS 510 and 510-T chargers for sure). So buy its own charger cable and label it and only use the Ego charging cable for Ego (an Ego charging cable can damage slim 510
batteries)
And you can use any of your 510's atomizers and carts (or cartomizers which is what most people use) on Ego. However the Ego can also use LR (low resistance hotter) atomizers and cartomizers but those are for Ego only and can damage slim
batteries.
And NOTE - the Ego charging cable needs about 4.2V 420mA of power so you cannot use it on any AC to USB that provides less than that. You can use it on an standard AC to USB that puts out 5v and at least 420mA or on a computer's motherboard USB slot (5v 500mA).
And another note - the Ego battery won't make anything hotter - it just have more charge than slim 510. if you want more heat too consider a Riva 510 SE battery from Liberty-Flights.com (or any of the Riva 510 kits there) - their kits and SE
batteries are 3.7v and will vape your 510's stuff hotter than the slim 510 does. Press the 20% off upper left front page before shopping on that site so you are looking at the lowered prices. We know all fo the kits are new stock 3.7v, the Riva SE has always been 3.7v, but their non-SE loose battery stock may or may not be.
