Golisi O4 Charger Review

Updated on: 2018-11-22


What’s up, everyone? DeucesJack at vapinginsider.com and today, I got a new charger for you. I got the Golisi 04, four bay charger, fits 21700. One slot is good for two am charging, fully automatic, no buttons whatsoever.

Let’s cut down low. Let me show you the packaging. Let me show you the whole charger, all the bells and whistles that it has, then we’ll come back on top, we’ll just talk about it. We’re not going to do cons and pros because it’s a simple charger but we’ll talk about it a little bit. I’m going to see you down low.


From Top to Bottom

Alright, everyone! Welcome to the down low portion of this video. Today, we’re going over the Golisi 04 smart charger, wall plug, 2 amp fast charging. Read all this if you want to see. An automatic current distribution, anti reverse protection, intelligent temperature control, those are some of the features. You can pause it here and read it if you want to. On the side of the box, you got your scratch and check. It also tells you what types of batteries that it charges. Check it out. This one will charge 21700s, no problem.


On the back of the box here, we got some more features, again. Pause it if you want to read it. On the back here, you’re going to see some more specifications. Pause it if you want to read it. Let’s open this up and see what we got. Look at that, nice bag. Check that out. I’m definitely digging that. Pull the charger out. Here is your 04 instruction manual. Got 2 amp fast charging, no button operation. All the instructions seem pretty straightforward. Here is the plug that’s included. I love the fact that this is a 4 bay and I don’t have a brick on it. Awesome job on that.


Let’s plug this in and let me show you what we got here. See all the lights? Nice, flashy lights. Nice spring loading over here. On top here, we got a nice big battery contact, a little bit of Golisi branding, some venting over here, some more specs over here, some more venting and some more venting over here. Nice lightweight, I like the feel of it. It does feel like it’s well made. I’ll definitely give that to them. Here’s some of the batteries Golisi has sent me. This is the s30 18650. We’re going to put that in over there. You’ll see, as soon as I put it in, you can see how much it’s charged and the part that’s not charged is blinking. Kind of cool. Here’s another Golisi battery the G25. Put that in over there, same thing.


Here’s the real test. This is a Golisi 21700 S35. Let’s see if it fits. We’re going to put it in the 2 amp slot. Look at that, fits beautifully. Now you’ll notice, this one’s about half way charge because the two bars are missing. So it is telling you something that your battery is doing. That’s kind of cool. There’s no button so it’s a simple battery charger, it really is. Some people are in the market for that. That’s what they want.

Now, I’m not sure because I’m not like a techy battery guy but what I’m thinking is you’re only getting 2 amps on this one if you are charging this one alone. In other words, these two have to be empty for you to get two amps on this one. If you have four batteries in there, I’m assuming that you only get a half an amp per battery because that’s what I’ve seen most chargers do, like this. Now, it does have individual ratings for the bays and the instruction manual and what it’s saying is bay 4 or actually, bay 1 gets 2 amps. This one gets one amp, this one gets 0.65 amps and this one gets 0.5 amps. I’m assuming, that’s if you have no other batteries in there. Like if I want to charge this one at a little over a half an amp, I put it here. If I want to charge it at one amp, I put it here and if I want to charge it at 2 amps, I put it here. If I want to charge a half an amp, I put it there. I don’t think those are the numbers you’re getting with all 4 bays filled. I think you’re only getting those numbers when that’s the only battery you have occupying those bays. So if you want 2 amp charging on a single cell battery, I’m pretty sure that you have to use this with only one slot.

But I’ll tell you what, man. It’s a nice charger. It’s a nice light charger it’s definitely good for travel duty. That’s for sure. Especially with that nice bag that they gave you.

Let’s go back on top. Let’s talk about it and then we’re out of here. See you back on top.
