Bruce..The link below is to the GX site. It tells you about the batteries in the description.They also sell a converter that plugs the compressor directly into a wall outlet.https://gxpumpofficial.com/products/gx-e-l2-portable-18v-cordless-pcp-air-compressor-4500psi-300bar-1-x-7-8ah-lithium-ion-battery-included-or-110v-to-18v-converter-sold-separately-for-home-outlet
A GX-E-L2 battery powered compressor. It's pretty small, and not too heavy to pick up and carry around with a padded handle. It fills a small PCP tank or airgun in not much time at all. I like it as it is fairly quiet so indoor use isn't a problem. Been hand pumping quite a while, this is a lot easier. About the only thing I don't like is the charger takes 2 hours to charge the battery, and there's no feedback or battery charge gauge. The idiot light changes from red to green, there is no in between state. Supposedly it takes Makita style batteries, but I'm not sure which ones are a guaranteed fit. Sure can't tell by the "non-existent" specifications on Amazon. Half the time there are no dimensions at all, or they dimension the carton rather than the part. Most of us would like the largest battery that is guaranteed to fit.Other than that, it's quite nice. Filled up a P-Rod from 500 to 3000 psi in no time. Don't know how long it will hold up, but so far, it is a big win. It has a small leak down, but at the moment it's not significant. Soapy water shows no bubbles. So I will monitor that. Got it on Amazon with a $35 off coupon, $281.79 delivered to my door.
Ordered a Diana P-5 pistol today from PA. Charles
