Basen Cube 2 Battery Charger Review

Updated on: 2019-12-21


What’s up, Insiders? Today we’re going to be going over a battery charger. I was over at ECC. The girl from the ECC booth, she ran out, she handed me a bag, gave me some Basen batteries and this dual slot charger named the Cube 2. So let’s go down low, let’s take a look at it.

Before we get into the video, a couple of days ago, we hit 25,000 sub. We’re giving you a huge giveaway. We’re going to have five, yes count them, five separate prizes. And there’s going to be eight winners in total. So make sure you go over to our Facebook group and you join up over there because the giveaway is going to be over there.

From Top to Bottom

Check it out. Let’s see what we got here. Reverse polarity protection, active over discharge, low heat, and charging intelligently. On the back here, it lists some of the features. Pause it here if you want to read that, no problem with that. On the side here, it tells you what batteries it’s compatible with. I will put a 21700 in there to make sure it fits.

Let’s open this thing up. You just pop the thing open. There’s your cube right there. You have a rather long cord for it, I like that. Here’s your warranty card, here are the features, here are the specs. You can see that it will charge two batteries at one amp. And here’s a list of the batteries that it’ll charge and here’s also some of the measurements. As far as width and height goes, it’s 2.6 inches x 5.2 inches x by 1.14 inches. It weighs 120 grams without the power cord. Let’s take this power cord and let’s plug it in. The first thing I like about the power cord is it does feel nice and rubbery. It feels premium, it really does. And I like the fact that there’s no brick. I don’t like using bricks. This is going to be good for traveling because all you got to take is the cord and the actual charger. You don’t have to lug around the brick with you. I like that.

Let’s check out the spring action. That looks pretty good. I don’t know what those little diamonds are there. On the back, you can see, we have a little bit of venting. We also have some specs on the back right there although they’re not very easy to read. I wish that would have been done clearer. Maybe you’re better off going with a sticker back here, fastened. But you can see, spring action is nice. I wish this was done in a different color. Nice contacts, battery contacts over there. Definitely wide enough to house a 26650 even though I don’t know a lot of people that use them now.

Let’s see what batteries actually fit in it. But let’s plug it in first. In order to plug it in, you just plug it in right there. You take your little plug piece and plug it right in, just like that. Now you can see that the diamond is in green. When you add a battery, the diamond changes to white. That lets you know it’s charging. Here’s the weird thing. I’ve tried several batteries, several 18650 batteries, they fit. But for some reason, the light doesn’t change. So I’m not confident it’s charging. If I do a 20700, turns to white. Now you might think maybe that port is dead. Let’s put it over here, still green. So that’s one back type of battery. Let’s try a Golisi, nope. Try it on that side, nope, it’s not charging. Let’s try a different Golisi, nope, nope. Just so you can see that I’m not trying to pull one over on you, guys, here’s my Xtar dragon VP4 Plus, one of my favorite chargers. You can see the Golisi is at 81%, you can see that this battery is at 90%. So they’re not fully charged. You can see clearly the red lights. Let me take this out, put it in there, nothing. Take this out, put it in there, no jump cuts, nothing. I don’t understand why this will not charge 18650s. I can smush them around a little bit, it’s just not making contact, but it makes contact on this charger. I don’t know what to say. It clearly states on the packaging that it will charge 18650s. There it is right there. But you can tell that mine’s not working with 18650s here. I kept it just sitting there, still the green lights. Yet if I put a 21700 in there, there’s my white light. If I put a 20700 in there, there’s my white light and it’s charging. So in all honesty, I can’t recommend this Cube 2, especially if you just have 18650 batteries. This thing’s going to be kind of useless. Kind of shock, not going to lie.

Alright, Insiders! We’re back on top. As you saw down low, I really can’t do cons and pros on this thing because it doesn’t charge 18650s according to its own lights in the manual. I kind of feel bad because the girl that handed it to me at ECC, she was all excited about me reviewing the Cube 2 and I’m happy to review it but I can’t recommend it if it’s not charging 18650 batteries which is probably the most popular battery in the vape market. The only thing I can really say about this thing is it’s a huge fail. Just stay away from it. There are other dual slot chargers out there that will actually charge 18650s. I don’t know if I got a one-off thing here. I’ve tried it in different outlets, so it’s not the outlet. I did everything I could to get this thing to charge 18650 batteries and it just won’t. For some reason, it has no problem accepting a 21700 but the 18 650s just aren’t working in it. So that’s going to be an abject failure. There’s nothing more to say. I can’t tell you to go out and buy this thing because it just doesn’t work the way it should. Maybe if Basen sees this video, they want to update, they want to send me an updated version or maybe I got a janky one, I don’t know. But I can only review what a company puts in front of me and that’s one of the reasons you why we’re here.

Let me explain to you a little bit of a day in the life of a reviewer. That’s one of the reasons I hate when companies only send me one product. Because this has happened before with vape devices. They send me a janky one, it breaks, you know what I mean. I’m halfway through the review, I can’t review the product. Same thing happened with this, it just happens to be a battery charger. Companies, if you want your stuff reviewed properly, you’re probably better off giving at least two products just in case something goes wrong. It just makes life so much easier.
