The Best Fast Charger for Electric Unicycles

[@RadiantFreeEnergyResearch]

I have been utilizing the roger charger for several months continuously, and this charger is an absolute masterpiece of electrical and mechanical engineering. when i first purchased this charger, i felt intimidated by the idea that i had complete control of the voltage, and the amps/current which charges the battery. after watching a couple of videos on youtube about how to use the roger charger, i learned how easy and natural it is, to adjust amps and volts, for the batteries i charge. i never thought the day would come that i could utilize one powerful charger, to charge all of the different voltage and current needs, batteries that i have on many different scooters that i ride. this charger is a game changer, and a dream come true. and roger is an amazing gentleman. and highly intelligent. thank you for making this video. this video help inform, and inspire me to buy my first roger charger. and now i cannot imagine utilizing any other charger, for all of my battery charging needs.

[@ShaneHilde]

That looks very similar to the GTK charger I bought last year through Archee. That was a great charger! Charging EUCs has come such a long way in the last few years. Remember when we thought 5 amps was fast?

[@Hunter_Heart]

This is a must have fast charger going forward.

[@rogerunderhill4267]

Fantastic observation about the higher energy input at the same current for the higher voltage wheels. I hadn’t thought about that before. Almost reason enough to upgrade to the higher voltage wheels.

[@roccatagon]

thanks for presentation, could You give us exact weight and dimmensions of this charger ?

[@zogly9469]

Thanks for the information, Marty. What happens if you charge at a higher rate than the manual for a wheel recommends? (My V12 HT's limit is supposedly 8 amps. If I tried to feed it more, will it charge fine, or does that risk damage or fire?) Even if I have to turn it down to 8 to be safe, this will be a nice charger to get once I start doing longer rides. (My stock 2.3 amp charger is good for now.)

[@roghaj]

Thanks Marty 🎉

[@justinspirational]

I have one and highly recommend.. especially if you are planning on having more than one wheel with different voltages.. nice and compact and will fit into most backpacks for long distance riding

[@Sleeplesskangaroo]

Great video Marty. I just got myself a monster pro and have a fast charger very similar to yours. Looking forward to getting some miles in! ✌️❤️

[@ElectricUnicycles]

I love my Monster Pro. You'll have lots of fun upcoming.

[@WickdPerfekT]

Hi, what v and A would you max out on charging the hero?

[@ElectricUnicycles]

The Hero is a 100.8-volt wheel. I'd stick to ~10-amps max.

[@EUCWayOfLife]

Hey Marty! Love your videos! Quick question, what do you charge your Mten4 at? I was told by a dealer 5A was fine and have charged at 5A but then was told by Milli 3A was max. So curious what you do and why. Thank you!

[@ElectricUnicycles]

I'll charge my Mten3 at ~5-amps. I haven't tried more but considering the size of the battery 5-amps is more than enough. Same for the Mten4

[@ETAonTheEUC]

I can't seem to find the max amps the Commander Pro can charge safely. How do you determine the max amps an EUC can charge at? If I knew then I could set the fast charger for that amperage. Thank you

[@ElectricUnicycles]

This information is usually determined through community trial and error. 10-amps is a conservative maximum values (which at 134-volts equates to a very fast charging rate). Typically we've been able to charge the 134-volt Begode wheels at 12-amps.

Hey marty, how can I get my hands on one on these chargers !! I'm in the UK??

[@ElectricUnicycles]

Absolutely. Roger ships all over the world and the international shipping is very reasonable. Join his Telegram group.

[@SergeTarkovski]

Any idea of its weight to know how much weight it will put on the back in one's backpack?

[@RadiantFreeEnergyResearch]

May i ask if the roger charger is auto sensing, meaning, automatically adjust to voltage input of 110 and 220? I just ordered an alien rides j1772 to 5-15 plug adapter to facilitate charging my wolf king gtr scooter from level 2 charging stations. I purchased my roger charger some time ago, and just recently began using this charger, which i love very much!

[@ElectricUnicycles]

Yes, it absolutely does auto-detect the input voltage.

[@RadiantFreeEnergyResearch]

Thank you!

[@GitDatPC]

I'm charging my Commander Pro 50S at 26A via a J1772 adapter with this bad boy 😁👍

[@ostumbling]

Nice vid! good info

[@xorbe2]

Is that an analog knob for setting the voltage? Can it be accidentally bumped while charging or does it "lock in"?

[@ElectricUnicycles]

The voltage adjustment probably takes a couple of revolutions to change it 1-volt. Bumping it would not really change it. This charger is for advanced users. "clumsy" users should buy a different charger LOL

[@xorbe2]

@@ElectricUnicycles You would be shocked how crude the internal pot is on the stock chargers!

[@ElectricUnicycles]

@@xorbe2 I wouldn't be 🙂I had to adjust the pot on my S22 charger - it's extremely cheap!

[@RCDevotee]

Thanks Marty and Roger! Do you find the lack of 220v switchable option a problem? I know the long distance riders I know need 220v in order to use the electric car chargers.

[@ElectricUnicycles]

It auto-senses the input voltage so it'll work with 110 or 220

[@RCDevotee]

@@ElectricUnicycles That is awesome! So many have blown their chargers by forgetting to switch when connecting to the car chargers.

[@russellzauner]

Have you checked into any adapters that might let you hook up to a typical charging station?

[@noelleonard2498]

Those charging stations only exist on television though.

[@ElectricUnicycles]

Yes, the EV charging station adapters for EUC's are commonly available and I've used them.

@@noelleonard2498 WEST COAST ELECTRIC HIGHWAY The “West Coast Electric Highway” is an extensive network of electric vehicle (EV) DC fast charging stations located every 25 to 50 miles along Interstate 5, Hwy 99, and other major roadways in British Columbia, Washington, Oregon, and California. The initiative is a collection of projects, funding sources, and partners with the same vision-to provide a network of fast charging stations enabling electric vehicle drivers to make longer trips and travel between cities. The Washington State Department of Transportation leads the charge in Washington. The Oregon Department of Transportation heads up efforts in Oregon. A California Governor’s Office interagency group coordinates charging investment in California. Plug In BC, a collaborative among government and industry partners, is the information hub for British Columbia. The west coast has a robust EV charging network with hundreds of DC fast chargers and thousands of Level 2 charging units.

[@russellzauner]

@@ElectricUnicycles maybe do a short showing how they're used, costs, maybe there are different types, sometime? I know of them but haven't really got a lot of data or recent demos that I've seen. I wonder if we could get the super fast charging working so you only have to stop for a few minutes if you're only charging up something small like a PEV...? That would be cool - stop at the store and by the time you get your soda your ride is charged back to 100%

[@OldSloGuy]

A real touring solution. Back pack freindly.

[@greensark2417]

I’m in line.

[@Roskellan]

The charger works on my Master (50e) at 9A quite well. Could go more I guess, but I think 9A is a sensible limit given the battery size. You can 3D print TPU bumpers for the ends of this as well, available on Printables. I bought my charger from AliExpress, so I had to make up my own cables.

[@ElectricUnicycles]

Yes, I now have those 3D printed bumpers for my charger

[@Roskellan]

@@ElectricUnicycles Dawn Champion put me onto the bumpers, thank you Dawn :-)

[@ETAonTheEUC]

I plan on getting a similar charger for my Commander Pro soon. Do these chargers automatically detect the max amps to charge the EUC batteries? For example, I do not know the Commander Pro max battery amps to charge safely, so will these types of chargers automatically detect the max amp charge? Obviously, I don't want to put more amps into a charge than I need to keep the battery safe

[@ElectricUnicycles]

@@ETAonTheEUC It's impossible for any EUC charger to limit the charging current based on the wheel. Personally, I stick to 10-amps as a maximum.

[@mo_euc]

How does this compare to the "fast" charger eWheels sells?

[@COBARHORSE1]

Much more powerful, and more versatile. You can adjust the output voltage limit, and the current output limit. Not as plug and play as the stock charger, or the other fast chargers. You have to know what you are doing, or you could overcharge your batteries. One thing Marty didn't mention, is that it can take 220 volt input, so you can use an EV charging station if you can't find a normal 110 volt outlet to use. That is very helpful with a larger group ride.

[@mo_euc]

@@COBARHORSE1 thanks for the details 👍 Much appreciated!

[@vtran1082]

[@ElectricUnicycles]

4-pounds 7 ounces

[@CadeBrazil]

Ps. for eWheels S22 with Samsung 40T (1C) will just be charging by ~13.5A from this 15A charger juice. It doesn't hurt the system (BMS), just make sure by setting on 126v and nothing more than this. Then, be happy with more miles to came back.

Can it charge 84v wheels? And how about 220v, 240v outlets?

[@ElectricUnicycles]

It can charge any wheel from 1-volt to 140-volts. Roger can provide you with the necessary cable for the 84-volt wheel (at an additional charge). It's compatible with American & European outlets.

[@anh-tuancung3565]

Hello, what is the difference between this charger and the ones from AliExpress?

[@ElectricUnicycles]

Probably cables and a dedicated Telegram support group

[@roccatagon]

Did You checked it with some voltmeter, or maybe by some specialist, if it gives steady power without surges, if it is safe for euc battery? From the outside it looks little schoddy..., like unfinished device.

[@ElectricUnicycles]

This is a fast charger for "power riders" that need to charge their wheel fast while on long rides, etc. If aesthetics is important than this is probably not the right product for you. The wheel BMS can take care of over-voltage on the input but I doubt this is an issue with this charger. Many of us have been using it for months with zero issues.

[@roccatagon]

@@ElectricUnicycles I know its for cruisers, so its for me exactly :). One of very few fast chargers for 126-134v. I asked about measurements bcs. Daniel from euc service claims, that steady charging IS important, and big voltage fluctuations during charging can even damage BMS. My friends also use this charger with Shermax (for now without problems), but I dont know if anyone tried to verify it in professional electonic service. Maybe it only looks bad, and inside is first class device - worth to know before buy.......

[@ElectricUnicycles]

@@roccatagon Sadly I can't really confirm the quality of its design. It certainly "feels" much higher quality than the chargers that come with our wheels. I bought it because Roger had been using it and he was satisfied with its quality (he also builds custom battery packs so he's been using "all things battery related" for a long time). Seems to be working great for all the local riders who've been using it. I would say that if you're worried about it, don't buy one 👍

[@maartenrischen4132]

Noob question: how do I change the voltage?

Hey Marty, I just Ordered a ex30 from your buddy Lem and I was wondering if Roger or anyone will sell me those adapters because I already have a fantastic high speed charger from Korea that has the yellow input that you connect your charging cable to. I just need a set of those cables for the ex30 and s22 ... ( basically the ones roger sends when u buy a charger... I was wondering if you know if he sells them without the charger. I would appreciate it. I am in the EUC underground and my name is : SavetheRepublic .. I just ordered a ex30 from Lem ... Thank you for all the videos you make, they are wonderful. I am a similar age to you but live on the East Coast... Jersey Shore .} Hopefully I will start making my own videos on my ex30 when it comes in June. Thanks for everything you do and let me know if u know of a place that sells just those charging cables as I cant find any ... Cheers Dan

[@ElectricUnicycles]

I don't think that he does sell the cables separately since he provides the cables as an enticement to buy the charger from him. People can buy the charger cheaper elsewhere but than you have to deal with making the cables. You can always join his Telegram group and ask the question there.

Shilling for someone selling a $120 charger for $290? Is this an accurate representation of the EUC community? EUC's aren't my thing but this is disgusting and I would be embarrassed if a community I was part of had this level of slimey money grabbing instead of just helping others out by providing them the link to this charger on Aliexpress. And no, Aliexpress is not dangerous to use or sketchy or whatever. I've made over 100 purchases on Aliexpress and in the past year they haven gotten even better on disputes. So long as you provide evidence that what you received is not what was advertised (and put it into very plain Kindergarten level English) you WILL get a refund and you will not have to return the item at your own expense...or return it all. I've probably done 10 disputes (I buy electronic stuff and some of the stuff I wouldn't buy if the dispute process was risky) and only a couple times have I had to re explain/provide more information to make the human at Aliexpress understand why the item I received does not match its listed specifications. I have NEVER lost a dispute. I've purchased accessories for a product since it arrived with them broken..TBC
