iSDT K2 AC/DC Smart Charger Review ⚡
These guys are pumping out chargers every couple of weeks it seems like, but maybe like maybe once a month or so new model comes out and um. Actually, this one’s been out for a while. I i haven’t had time to take a look at it. There’S not a whole lot of differences here between these and some of the older models, just kind of move things around a little bit and maybe add a few features, but in terms of the specs of something in terms of all, you know like the capabilities it’s. Maybe slightly improved over the older models, but not significantly. Obviously, if you’re in the market for a charger, you probably want to get the more latest models versus something that’s older, of course, that’s kind of personal preference as well. Now the big thing with this one here is the way it does the ac versus dc power setup here, and this is uh. This has a built in uh ac to dc inverter, so you can plug in the included ac cord here, and this is the cord and you see, it’s a right angle. So when you plug this in this is the major feature of this charger. That’S different from the older ones you plug this in, if you’re at home, you’re charging on ac, you can’t accidentally plug in an xd60 battery and below the charger it’s a safety feature here, and vice versa. If you have a xd60 plugged in for dc power, you can’t inadvertently plug in the ac power cord and glue the inverter inside.
So they have this little design here to prevent accidents and which is always good because you don’t want, like you know your electronics blowing up on you, batteries catching fire, etc. It’S, a pretty big charger, um i’ll show you what this looks like compared to my d2. This is the yes, i still have the dt from like three years ago and still works and works great, and the k2 is pretty similar um to the d2. The d2 is um ac. Only here, as you can see, and now the k2 is a ac and dc, and basically you have the dual channel. You know uh 6s capability charger here with um at home charging or in the field charging. If you have a really giant battery something like this here, success, uh 5200 milliamp hour, i’m sure there’s, even bigger batteries out there, if you’re doing fuel charging um, then you want a bigger charger with more capabilities than this might flip the build here. If you wanted to have something that works out at the field and also at home, but quick, look at the charger, you got a fan here, vents here in the back, and the fan this size obviously looks like each channel has its own fan here’s. The bottom. Look at the specs here in the manual in a moment: um – nothing yeah, regular buttons here you do get the manual of course, look at that in a second stickers as usual in the screen protector, it does come with a temporary screen protector here that you know It looks like it’s all scratched up.
You can just remove that, of course, and put the included screen protector on there. I just uh lazy didn’t want to take that time to put that on 6s. Only here, not 8s xd60 for each channel. You get a usb type c port here. You can turn on and off in the settings and i believe the default setting is off and it’s used for firmware updates, um, typical isdt. You can firmware updates on this now via usb, and if you turn this on, you can charge it. I think it’s at 5, volts 2 amps to a usb type c, cable, which is not included, and you can type you know, charge pretty much anything via this usbc port phones, for example, are one thing that shows they show a picture that in their product page Let’S go ahead and let’s fire this up; okay, so yeah here it’s on two screen, uh, two, basically two channels on each side: uh, pretty small. I think it’s a two point uh three inches ago, let’s, actually let’s, look at the specs now all right. So here are the specs in the manual i’m not going to bother uh reading everything here off to you, i’m, just going to point out some of the important things. So this is dual channel um you’re going to get more power on dc versus ac that’s uh! Very typical it’s only 200 watts ac i’m, assuming probably about 100 watts per channel, but in dc you can.
You can get up to uh a thousand watts or 500 watts per channel, so that’s pretty normal. The discharge current here points you to one and a half amps per channel. You know not a whole lot up to 20 amps charging, um and 15 watts per channel discharging power so it’s going to take a while. If you have a big 6s battery to discharge it just keep that in mind, it’s going to be sitting there for a while discharging, and you have your uh typical, normal um battery types here i don’t think i see anything unusual or different here, it’s all pretty Much the same so in terms of the interface on here we have three physical buttons, no scroll wheel now and up and down buttons, and i think, uh to choose a channel. You press the button on the right. This is channel two over here. It says channel one yeah and it doesn’t say in here which uh channel it’s on it just says: k2. You can see that there’s a little bit of a line here, so you can see that most of the screens on this side says that indicates that’s channel two. And then you see the line moves over on this side, and that means that this is channel. One doesn’t show what the pack voltage of the connected battery is that’s different, usually that that will show up on the screen here. Um let’s see if we long press channel the channel one button brings up the task setting.
So here you can change your typical settings. I have to use the buttons corresponding with that channels. These buttons over your channel too don’t do anything. So you can change your typical tasks from charge, discharge storage and destroy that’s uh, totally uh the same as before. Chemistry choose your battery type here. Also you change the end voltage number of cells. You can choose that uh, usually um. It will detect that automatically. So actually i’ll plug in a 2s here and we’ll see what it does when you plug it in, and then you obviously change your current here and hit start i’m going to get into the actual charger settings. I think you long press both center buttons brings up the advanced menu here and then oh there’s. Another thing another feature dc power to channel one. It doesn’t work on channel two. So if you want to use this as a dc power supply, you can adjust your voltage here so say. If i want to make this a 16 volt power supply at it looks like the maximum is 5 amps, let’s say at uh 4 amps. Then this output, here on the xd60 on channel 1, will output 16 volts at 4, amps, basically consistent power. So you use that as a power supply – and all i have to do is toggle – that on and off here, so it’s going to be on or off and then let’s go back into the settings again and then, if you want to go into the main system Settings you bring up that menu and then hit the system settings button, and then here under lowest input, voltage and max input power.
These are not adjustable on ac power. Only on dc power. It gives us your back light. Your volume for the tones completion tone usb charge here you can turn that on or off and then they’ll enable the usbc ports for power i’m going to leave that off the split screen thing here. That means that after 30 seconds, it’ll it’ll actually um go from the single screen to the split screen. You can adjust that you can actually turn that off or adjust it to 60 seconds, and i don’t know who who uses backgo anymore it’s. Obviously isdt has been pushing that, but i don’t i don’t have any backup batteries and i don’t know anyone how he actually uses them theme here, bright, right or dark. So if you want night mode, you can do that looks like uh. The bright is actually easier to see uh. Basically your channel calibration. If you want to adjust your end voltages there, you can adjust that this one seems to be calibrated and then this is your system. Information yeah that’s, pretty much it here, let’s see if they miss anything important, look like it yeah there’s like basically, you know, um it’s, pretty much like all the other isdt chargers in the past, not really all that different let’s go ahead and do a little test Charge test demo got an xt30 battery here so i’m going to use a little adapter to convert from xd6030 and you want to plug in the balance lead of course – and this is yeah – this is opposite of toolkit rc.
The balance plug is upside down. The negative is on the left all right plug that in and we can see that we’re on the split screen now this is timed out and it’s detected that it is 2s current pack voltage is 7.6 volts, so let’s go ahead and select that channel now we Can see the breakdown by channel or by cell 3.8 tiers is pretty much a storage voltage and then yeah all the same screens. Here let’s go ahead and long press and it’s automatically detected to us and yeah yeah, one amps fine. This is like a 2200 milliamp hour 2s battery charge. Lipo all looks good hit start and now the fans are kicking on and actually it’s kicking on on both sides. Even though only channel one is charging and so it’s not super loud, but it’s it’s. You can definitely hear it from distance let’s see here how long it takes before the internal resistance numbers. No, the internal resistance numbers came up pretty quickly. Yeah, you can see your milliamp hours going in current charge and estimated pack voltage 50 percent yeah pretty typical here: charger stats, 10 watts. This is 10 watts coming from the battery that’s powering the charger and then the 7.7 volts and 8 watts is the power going into the battery that’s being charged all right. So we can see we’re at 3.86, volt squared and stop this. I just press the center button here. You can adjust the current in in mid cycle if you want that’s same as always let’s stop here and i think the voltage will come down a little bit and the fans turn off.
So nothing. Nothing really that surprising. Here everything is uh, pretty much working like all the other isd charger, isdt chargers that i’ve ever used before. Yes, i think that’ll cover for this one. If you want to like go back and look at my older videos, i have a Music battery charger playlist and you can compare these to some of the other older isdt chargers, see if there’s any differences that you notice um. Obviously it looks pretty much the same to me, uh. Obviously, obviously the biggest feature here is the ac dc capability. It does make the charger bigger, but if you just want one charger and carry it around from uh home to the field, then yeah, maybe you want to check this one out anyway, links this way down in the video description.
