hold a good charge

Excellent item thoroughly recommend

This charger is perfect for recharging Dewalt 20V batteries or its replacement batteries to full power. Even though it is small in size, its charging speed is quite fast.

I ordered this low profile Makita charger off of Amazon vine to have for a backup to my normal one. No problems with it so far. Charges just as fast and takes up 1/4 of the room of my normal one. I usually keep this one in my small bag with a drill and two batteries. What I like the most about it is its size. It is not bulky. Can fit just about anywhere. It even fits in my case for my drill. Right where I would usually put a box of drill bits. It has all the standard features a regular Makita charger has. Tells you if the battery is defective. charged., charging or overheated. I think it is great. A nice backup or add on for Makita tool users. Great to have for emergencies or if your normal one breaks. Thanks a ton.

Definitely comes in handy in a pinch. Good quality build.

So let me start with the bad the one big fault with this that I found really the only one I found thus far is the fact that wouldn’t plug down to a battery or one plugged it doesn’t really matter, but to plug your USB into it in order to charge say your phone the issue I’ve come defined with it is that especially if you’re using an adaptor on your USB-C cord to the standard USB type cable you don’t have very much clearance because your 5 V or whatever it is out your USB output let’s call it is right at the top and instead of coming straight out it’s at 90° to the top so it’s pointing down it’s pointing down where the battery flares and if you happen to be using large capacity batteries with this like the first battery, I grabbed was a an aftermarket 9 amp hour high capacity battery and truth be told. I only have high capacity batteries. The ones with the large square base. It’s doesn’t appear like it would be in the way for your average you know 1.5 I think the two amp batteries are like that as well. I don’t think it gets to the large square base until the three amp batteries. I think I can’t remember. I don’t have any of that style so I can’t say one way or the other now with that said it does fit it just takes a little bit of finesse, holding it between your thumb and your index finger and the OK symbol per se, and kinda chiming it in or you could just plug it up while it’s not connected to a battery and then it will not charge your device until you press the button at the top, which is a nice feature. There’s also a what appears to be like a nine or a 12 V DC barrel jack output it’s labeled. I don’t have anything to plug into it to try and then there’s the USB-C on the very top which is an input and it has a silicone flap door that block it off from dirt and debris, which is a nice touch the other ones I don’t think really need it. The USB definitely doesn’t. It’s facing downward and completely covered the barrel jack well it would be nice to see that covered, but it’s not really that big of a deal the one at the very top is gonna collect dust like crazy without it so it’s a great feature and no different as soon as I plugged my cord that I use for charging into it it stopped what it was doing. It went blank for a moment and then it started blinking as opposed to just having the lights on indicating that it was charging so it’s a two way charger. You can charge devices with it or charge the battery itself with it, which is an excellent excellent design no I have a real Milwaukee work light with the USB charging integrated into it and I will say it’s a good bit thicker and stir than this evening. It is, but I’m gonna give it a pass on that because that’s a legitimate work light it’s made to be bounced around and you know it’s a light first and charging port second where is this is a charger doesn’t matter what you want to charge whether it’s the battery itself or your device battery this is a charger and normally a battery bank essentially, I would have some grapes about it not having extra functionalities this one where it offers charging of my drill batteries but then I can also use my drill batteries to charge my devices and something gives me the distinct impression that the high capacity batteries for this are gonna offer me more cycles before needing to be charged to themselves then a battery bank will my gold standard or I shouldn’t say gold sander, but my bare minimum for device battery or the device battery but battery back up or a battery bank or however, you’d like to call it. The portable power packs is 10,000 mA if it’s not at least that I’m not really interested by that definition generally speaking I can expect to charge my phone from powered off because it’s completely dead to 100% charge once plus anywhere from 25% all the way up to 50% charge a second time I got a fair sized battery in my phone. It’s an iPhone 14+ now I don’t have a need to charge my phone right now. I’ve already charged it for the day, but I am out of curiosity going to be trying it with these nine amp batteries because unless I’m doing some incorrect math that should be 90,000 mA so I should be able to get 10 charges. I’d be happy with eight honestly and that’s from like I said completely battery drain to the point where the phone shuts itself off to 100%, which is more than what most gold standards are based on. I think the average is like charge it from what they call it so 20% 25% charge is what manufacturers recommend as a bare minimum for most lithium batteries. A lot of devices will power down at that. Someone won’t and some will, but they still want you to stop it at the 20% mark like when it’s marking 20% so there’s a built-in buffer there but generally speaking it’s charge from dead or 20% all the way to 80 or 85% so my general test of what’s this gonna do is a little bit excessive I guess but my workshop is in off grid barn. Everything I do is ran off of hand tools, manual actuated equipment and with the battery packs and it didn’t take long to figure out that certain things just weren’t valuable to run off of a BLUETTI portable power station things like fans and vacuums really the only things that I don’t have a solution for at this point is air compressor and I don’t mean just to fill tires I mean in order to run air tools if need be ordered to spray paint that type of thing might use of a compressor is small and I can get around that with a with an extension cord, but everything else that I have is generally cordless and I prefer drill batteries for lack of a better word whether that’s the 18/20 V max type batteries or the M12 battery platform from Milwaukee, which is my only 12 V platform at the moment so the idea is to have as much as I can run off of whatever brand battery. It happens to be but run it off these style batteries because they’re plan a full. I’ve got a lot of of them and I can generally finish a task with it and then switch over to a another tool with that same battery as opposed to things like my current vacuum for their for major issues I’ve got a shop vac hung up on the wall, but I have a little Dustbuster style, but it’s the perfect example of what I’m talking about it uses DC lithium bed used to run, but it takes an 110 outlet to charge it that actually eats up a good bit of juice from my portable power station and the idea is the portable power station is more or less there too run things that I don’t have cordless versions of or run corded back ups while batteries charger, whatever the case, but for the most part what I’m aiming for at this point is for its job to be recharging drill batteries cause that’s the one thing I’ve yet to get a good solution for this just changed the game in a sense at least for one of my main platforms because now I can charge batteries with USB and you would think that it wouldn’t make a difference but for whatever if it’s charging something, it doesn’t matter what if the draws the same and the capacity of whatever I’m judging is the same the amount of power it takes to run the inverter is the only thing I can figure is enough of a difference that it makes a difference if I plug my phone into that portable power station direct versus plugging it into a cube. It’s going to take less charge to direct so it remains to be seen how long it’ll take to charge these batteries from stone dead and I’m not sure what kind of protection is offered in this device if any for drain charge your battery. It has to have some sort of overcharge protection, but I wouldn’t be leaving it plugged in and then go run errands or what have you that’s for sure I would definitely keep an eye on it and I wouldn’t leave my battery plugged in any longer than it needed, but that kind of goes without saying, I do the same thing with my actual brand name Milwaukee charger too, and I have more question when it comes to using lower cost aftermarket batteries than I do with using the actual brand of batteries but that same concern has been there since I started using these. I’ve learned that if you buy any of these aftermarket batteries if you go for the ones that have some sort of branding on them whatever the name you choose happens to be, but if the company is willing to put their name on the side or the bottom of these aftermarket batteries I’ve noticed that built quality and feature set and just overall components used are significantly nicer quality, but what that said I’ve also gotten some in the past that were a really really good deal. They were sold under whatever brand I can’t even remember, and when they arrived, they warrant branded no logos or stickers with the name on them anywhere just what it was the model whatever and then however, many volts, and however, many amps, and they weren’t as nice, but they were still quite nice and at the sale price that I’ve gotten that they provided a value that was as good as the value that buying the aftermarket batteries versus the brand new batteries has to begin with instead of being 50% it’s 75% the price of the original batteries 50% the cost of what I call branded aftermarket batteries and essentially getting the insides of the good ones or the same with cheaper plastic shells and cutting corners on some of the charge indicators on the batteries themselves so that for what it’s worth and what not yeah I guess the only thing I really can add is it would be really, really nice if they would have integrated an exceptionally strong magnet on the outside similar to the work light Milwaukee makes that way you can stick it on the side of your toolbox, for example which kind of helps keep things neat and tidy, and it would’ve just been a little extra but then again for the race I feel like suddenly I’m asking for a lot, especially for the fact that this will charge your battery and then it will use your battery to charge your devices that to me is pretty cool but the M 12 battery platform is quickly become my favourite of all time they’re small they’re handy. They have an insane selection of tools and there’s adaptors available that allow you to use very commonly acquired 18 and 20 V max lithium batteries with it and step down the voltage reliably to 11.4 V so you’re getting a little bit more power constant because generally speaking you only get 12 votes for the first few minutes of views and quickly drop down about 10.8 to 11 V and then hover is right around there and with the adaptors suddenly you’ve got all your 18 V batteries suddenly being able to use them and I’ve even went as far as using one of those adaptors with a second adaptor allowing me to use a third 18 V battery and tested the with a multimeter now if I’m not mistaken, I would have to double check, but I’m almost positive that it was Strictly stated everywhere when I got that adaptor that it was only to step down voltage on output it wouldn’t support charging because some of these support charge functionality. I have one here that allows you to use Dewalt style 20v batteries in 18 V Bosch tools and it supported charging the Dewalt batteries in the boss charger because at the time I had Dewalt batteries without tools for them and I didn’t have a charger yet. It was a case of I knew I could get adaptors I had acquired an angle grinder that was Bosch, but I didn’t have any batteries that were more than 2 A to run it so when the opportunity to get some five amp Dewalt batteries sprung up knowing how common they are the tools and what not I went for it I had traded along the way for some drills and such in the past and thought process being if I get the batteries now to run this eventually I’ll get myself a charger but for the short term, I will just use the adaptor because bear tools can be head for wood in today’s money is relatively reasonable prices in comparison really nowadays you’ll pay for a beer to what it used to cost to buy a single tool with one or two batteries and a charger, but I digress what I’m getting at is I’ve I had been committed to the boss for battery platform because of paying for your bucket at the time with the kid I bought to replace some stolen property it’s only relatively recently that I started acquiring others and I had always been told stick with pick up brand and stick with it that way all your chargers, all your batteries all your tools are all the same, etc. and to a point I agree with that wisdom, but in the other hand, I found that quite limiting Bosch isn’t the most popular of the brands are one of the bigger names, but top of of the heat as they would say, and then I got an Ingersoll rand impact, which was as much an aspirational purchase as it was a practical useful tool purchase and suddenly it’s I’ve already got this and that and then I learned about the adaptors so I gave them a try now they’re not the end BON I’ve learned with the 12 V adaptors that take 18 V batteries don’t leave your battery in the adaptor because it will potentially drain it. I’ve had a go both ways I’ve seen when I first gotten it leave it sit for well over two weeks and never have any change in the charge indication on the battery itself that and then one day I had taken it off to use another tool briefly, and when I put it back, I hadn’t seated it quite all the way in the next day when I went to grab it and we’re only talking about the span of like eight hours. The battery was stoned, dead something be aware of now they also suggest to not store your batteries in the tools to begin with. I think that’s a rule most people disregard for the most part personally, my rule is if it’s the tool itself with the battery it’s designed for or an aftermarket equivalent. I see no big harm in it if it’s not that’s a different story if it’s using an adapter, that’s when I like to see my batteries taken out. I’ll leave the adaptor in the tool in certain situations like my Dewalt battery to Bosch tool adaptor that stays in the tool the battery comes out in my Milwaukee adaptor that goes Milwaukee or DeWalt 18 V batteries to the Milwaukee 12 V that adaptor doesn’t stay in the tool as it is and the batteries definitely don’t stay in the adapter. I haven’t tried this charger with that particular adaptor yet I really don’t see why would be any different to use or any reason not to but like I stated previous it’s also not safe to charge with that adaptor it’s not made for that. I’m almost 100% certain and that it clearly stated it didn’t support charging. I’m quite certain that there’s only one adaptor that I’ve purchased out of three or four which support Charging and that was out of necessity and I tested it with two identical batteries with the same level of charge according to a multimeter, I use the thermometer to gauge temperature. I monitored them and they charged in the battery with the adaptor and a boss charger versus the Dewalt battery and technically it was a Mac tools charger. They’re the same as the Dewalt just in a different colour with a different logo but they charged two batteries of the same size brand aftermarket batteries, mind you roughly at the same rate to the same voltage with roughly the same amount of heat involved enough that any difference isn’t just marginal, but it’s within. Allowable tolerance and just various you can test something four times back to back with the same equipment and get slightly different results. There’s an allowable tolerance for that and just the difference between being 4 feet apart plugged into two different outlets in the wall a degree or a half a degreeC is well within the allowable tolerance and within the margin of error and I mean it takes so long to plug it in and it to start actually doing its thing but the difference in time it took to plug one in and then get to the other one and plug it in You see where I’m heading with that so that’s just the way I see it either way as I type this, I’m looking over and I went from two bars to one bar left to charge using a USB-C plugged into the wall and in particularly think it’s any slower or faster than What was to be expected and yeah, I’m impressed. It does the thing it does it. Well I’d like to see about getting more of these maybe by the same company but to do other brands potentially a thought in my mind time will tell but definitely definitely not getting exceptionally hot Actually if anything it’s a good bit cooler than the Milwaukee charger is and since I’ve unplugged the second USB cord from charging another battery pack I had unrelated to this. It’s actually sped up a good bit, but that’s because the charging cube or brick whatever you wanna call it Was charging two devices instead of just one so it cuts down on the amount of voltage going out which I need is something we all know you get the multiport chargers for USB’s as soon as you plug more than one device into it it’s gonna slow each one down Either way. I think there’s no reason this isn’t going to be a very very commonly used item in my shop I think I’ll probably get more use out of it than the normal person would outside of like power outages just because it’s off grid and to do USB charging for drill. Batteries is a huge deal For me anyway your mileage will most likely very, but it does the thing it does it good I can’t ding it for only doing one thing cause technically it only does one thing it charges that’s all it does, but it charges. It’s a charger as well as a battery bank innocence like it will charge your drill batteries and it will use your drill batteries to charge your devices so now the fact that it doesn’t have the flashlight or whatever else doesn’t matter the only thing like I’ve said that it’s missing is a strong magnet on the side of it, but there might be some sort of like electronics inside that are sensitive to the magnetic fields that wouldn’t surprise me and it not being shielded wouldn’t surprise me it’s coming in at the price point, but I also can’t see it not holding up either so happy charging
