PCP Air Compressor L3 4500Psi/320Bar/32Mpa,PCP Compressor with Dual 18V Lithium Batteries,Set Pressure & Auto-Shutoff,Paintaball Air Compressor Built-in Oil-Water Separator&Cooling Fan

I had my doubts about a battery powered compressor; but it has worked well. As noted in the title, I can completely fill my Avenger since abandoning my hand pump. More importantly, the compressor is faster and causes much less wear and tear on my body.Tip-1: Never start the unit “under load.” “Starting” is a multi-step process.1. Connect the hose to whatever you are filling2. Turn on the power switch and verify all fans work3. Press he chrome plated, possibly stainless, “On” button4. CRITICAL ••LAST•• STEP —Tighten the pressure release valve— the sound will change and the gauge will begin moving AFTER the hose fillsTIP-2 Rick Eustler recommended adding a ten dollar automatic timer to help estimate when to charge the batteries. After about 0.6 running hours—I expected 0.8—the unit stopped filling my Avenger at between 1000 and 1500 PSI. I realized that my batteries needed a charge. Rick suggested .8 hours; however he drains his batteries far more often than I do. I believer everyone’s milage will vary.Oh! I recommend this.

This is fantastic machine on its own. It has the power the durability and ease of use. Its portable and can be used anywhere!! However, depending on your reason for purchase...of your going to be filling alot of tanks at one setting you may want to buy the other versio. To it that uses electrical outlet Power source. The reason for this is because the unit comes with 2 batteries which last 30 minutes each. In addition to that the unit must rest for 10 minutes after 15 minutes of use. A typical paintball tank will take about 15 minutes to to fill....so you can fill up to about 4 tanks before wanting to charge up the batteries....unless you have multiple batteries.....but in most cases of your filling more than 4 tanks I recommend you getting both version units so that you you only have to worry about rest time of the unit. Other than that its a fantastic unit that is a must have for any body into hunting, paintball...Scooba etc.

Never received the product said it was delivered there was never a picture of the product left at the door or four digit PIN to give the driver for such an expensive item I've done everything I'm supposed to do even a police report and still no refund

The media could not be loaded. This compressor changes everything, with the ability to take this everywhere due to its portability. No more running out of air while at the range or camping or even while hunting.Filling up to 4500 psi without a problem, the GX Pump L3 is what we have all been wanting. This is the product of the year for me and I can't wait to use it again.Without the need for electricity.... I'm still blown away by the performance and portability of this unit.

Las baterías tiene un problema se calientan y no tienen rendimiento, solo pueden cargar un tanque de 1 litro 😑

The one reason that I purchased the PCP pump is because it pumps over the 300 Bar. This compressor pumps to 320 bar and since I have a Huben K1 (350 bar fill) I am able to fill the Hiuben past the common 300 bar fill rate. it actually fills at a good speed and I like the fact it runs off of it's own batteries. is that important? well, I also own the ones that you hook to your car battery, I did not have the car running and I drained the battery and was stuck out in the desert for 12 hours. I know, I am stupid for not having the car running. That's my story.

No issues, great for direct fill.

After powering compressor 7 times over perhaps 11 months, now both of the supplied lithium batteries have failed. Contacting manufacturer (Beijing) is email only, and they refuse to replace the batteries, nor make any adjustment, merely suggesting I use them properly. I finally purchase two Makita batteries, although locating the exact same original voltage is problematic, and compressor will not cycle at same speed. I do not recommend this unit, or any unit from this company (GX LE 4500psi cordless PCP Air Compressor)
