Hi guys,

I always had issues with off-the-shelf USB-PD mobile chargers/powerbanks where they just didn't have the available capacity or power output to charge my Macbook Pro so I took it upon myself to design one. Basically you plug the box into the Ozito battery like any other tool or accessory and it outputs USB-PD (Power Delivery) at a maximum of100W. I was able to charge my Macbook Pro from empty to full using a single Ozito battery so I'm pretty pleased with the outcome.

This is v1, v2 will also include 2x USB-A QC ports to charge your other USB-A/QC devices - I'm just waiting for the board to arrive from Aliexpress.

You'll need a few bits and pieces but they're readily available from Bunnings, Jaycar and eBay/Aliexpress and the overall cost of this is under $20. For those without a 3D printer, get in touch with me and I can print it for you for a price + postage.

Let me know your thoughts. I'm also in the process of designing a soldering iron based on the Hakko/T12 for the Ozito PXC battery too.

      Thanks mate. Hopefully the USB-A/QC charging module will arrive this week. I know that Ozito make a USB charger but it's only a basic USB-A 2A and I really wanted USB-PD :)

  • mapax on 26/02/2023 - 13:47

    Nice work. I’ve been thinking of making something similar but for ryobi batteries.

      Given how cheap the Ozito batteries are on sale, I thought the Ozito option was a better one and most of the cheapskates on here have Ozito batteries too. Stay tuned for the soldering iron too.

        There is some pretty decent USB-PD soldering irons out there like the TS80 or the (somewhat hard to get) Pinecil too, they'd work with your PD thing really well!

        • gyrex on 26/02/2023 - 13:59

          I wasn't aware of them. I'll keep going with the design I've been working on since it's an all-in-one solution which is quite compact. Here's what it looks like:

          https://imgur.com/tQwEq7n

          It's got an iron holder and sponge box attached to the top of it.

            @gyrex: This one appeared recently which lets a soldering iron pencil connect to it: https://www.thingiverse.com/thing:5805938

            Great job on the USB PD. I didn't know that SW2303 existed.

            • gyrex on 26/02/2023 - 19:20

              @skid: Yeh, that's the same kit I'm planning on integrating into my Ozito battery design :) It's a Hakko T12 kit and they're widely available on Aliexpress and ebay.

        A few of us are with ryobi thanks to all the cheap battery and tool combos that were $40 and all the other clearance/promotional tools.

    Hey this is pretty cool!

    I'm a Ryobi man myself, I think I'll make myself a Ryobi version of it (as a remix of yours) - Right now I'm rebuilding my Ryobi bench power supply from here: https://www.printables.com/model/159422-ryobi-one-bench-powe…

    Keep up the good work! :)

    • gyrex on 26/02/2023 - 13:50

      I can make a Ryobi version if there's enough support for it. Did you design that Ryobi power supply?

      • duk242 on 26/02/2023 - 14:08
        +1

        nah that one's not my design. If you want to grab a design that'll hold the battery well though, this one is way better: https://www.printables.com/model/137292-ryobi-18v-battery-co…

        I've got one on my Ryobi Powered Edifier speakers ;)

        • gyrex on 26/02/2023 - 14:10

          Should be pretty easy to adapt it to that. I'll try and find some time this week maybe.

  • bleemo on 26/02/2023 - 15:08

    I've got an Ozito USB C and USB A charger. It can Ah dle Samsung's "Super Fast Charge" but I don't think it can do any of the 45W or higher. Although I haven't tried…

    Bought from here:
    https://www.ebay.com.au/itm/374445434344

    High quality 3d print and yeh it's an awesome way to use those Ozito batteries lying around!

    • gyrex on 26/02/2023 - 16:39

      I had no idea this existed! Pretty cool little solution. Oh well, anyone can make their own now using my design and it does USB-PD up to 100W…

      It looks like that one from ebay only does 18W anyway - not enough to charge a laptop.

  • Fuzzy Toaster on 26/02/2023 - 22:20

    This is fantastic, nicely done. Really makes you realise how lame the ~15W official version is, considering it's around the same price. If I hadn't just bought a 100W Cygnett powerbank I'd build it in an instant.

    I'm very interested to hear how charging via USB goes - it might push me over the edge of doing it anyway haha.

    • gyrex on 26/02/2023 - 22:53

      Thanks mate! Out of interest, how many Wh is the Cygnett powerbank? The 4Ah Ozito batteries are 74Wh: 3.7V (nominal 18650 cell voltage) x10 (cells) x 2Ah (each cell is 2000mAh).

      I'm very interested to hear how charging via USB goes - it might push me over the edge of doing it anyway haha.

      Do you mean charging the Ozito battery via USB? The SW2303 is unidirectional ie. Ozito Battery -> SW2303 -> USB-PD. So you can't charge the Ozito battery via USB-PD. I'm happy to use the Ozito fast charger anyway.

      • Fuzzy Toaster on 27/02/2023 - 11:51

        I got this which is 92.5Wh. I forgot how expensive it was, far out. Now I definitely wish I'd done your strategy. Oh well, it was a work expense anyway.

        Oooh I misread your post and thought you were saying v2 could charge the battery, I see now you didn't say that haha. What board are you using for v2?

    For those on here who are interested, I designed the Ozito PXC 20V Soldering iron kit - it works really well and is super handy! Details here: https://www.printables.com/model/419935-ozito-pxc-20v-72w-so…

    This is awesome, thankyou for making it. I'm ordering a SW2303 from Ali to give it a go.

    • gyrex on 22/03/2023 - 16:32

      Great to hear! I'm working on a revised version which has USB QC 3.0/USB-A charging too.

      • datscheap on 23/03/2023 - 13:47

        I'll keep a eye on your thingieverse stuff. Prob will try your soldering iron also, after this project.

        Im hoping I'll get a v1.1 of the SW2303 board, altho if I dont, it will be handy to charge the lower power devices

        • gyrex on 23/03/2023 - 14:19

          Definitely get a v1.1 revision. I think the earlier revisions had some issues.

    Bit late to the party, but this is really cool. I saw someone had made an adapter to use power tools batteries with those cheap dc-dc power supply modules to make himself a portable bench power supply. See one of the picture reviews on this https://www.aliexpress.com/item/1005005513823999.html (direct link to the picture here https://ae01.alicdn.com/kf/A2bf0cd1345554f8897bd2fa786e0c444…)

    • theguyrules on 09/08/2023 - 13:42

      Just realised my Ozito PXC batteries are 18V, damn

      • impoze on 09/08/2023 - 13:57

        yeah they are 18V batteries he is using

        • theguyrules on 09/08/2023 - 14:05

          Oh yeah sweet. I'm gonna make this then.

            @gyrex: Brilliant! Thank you. I'm super keen to put this one together.
            Its nice to build something with links to buy the extra pieces at Bunnings.

    Thanks @gyrex for the great design.

    I've remixed it to add the second board with 2x USB-A ports here: https://www.thingiverse.com/thing:6163696

    Note that the screws to mount the boards need to be cut down to custom sizes with a angle grinder or hacksaw or similar, which I understand is quite annoying. If anyone wants to take it further, its definitely possible to get the fasteners to be off the shelf sizes only but the base has to be redesigned a bit.

      Great remix! I did design a USB-C & USB-A version but hadn't had time to print and test it. I've uploaded the USB-C & A version to my original design if you want to check it out :) I bought the same USB-A/QC board as you did.

      • naisuda on 10/08/2023 - 20:24

        Ah, you've mounted the USB-A board on the cover? Nice!

        • gyrex on 10/08/2023 - 20:27
          +1

          Yeh, seemed like the best place to mount it for simplicity :) I spent a long time trying to optimise the placement of everything in the box… Also, those spacers provide some airflow/heat dissipation under the USB-C board because it heats up quite a lot.

        Out of interest, did both ports work with your USB-A charging board? The first one I ordered had an issue with one of the ports so I ordered another one and this one also has an issue with one of the ports…

          Hmm, weird that you got 2 duds. I'm getting 5V on both USB-A ports and they both seem to charge my phone the same.

          • gyrex on 12/08/2023 - 20:15

            @naisuda: I won the Chinese manufacturing lottery I guess ;) I'll order another one.

            • naisuda on 20/08/2023 - 07:13

              @gyrex: Well waddaya know, I was charging something today and after 10 mins it seems one of the USB-A ports died after it's first proper use. It's looking like these boards are quite dodgy!

              • gyrex on 20/08/2023 - 07:45

                @naisuda: Thanks for letting me know. I'll order a different USB-A/QC board and design an alternative top around that.

              • gyrex on 20/08/2023 - 11:49

                @naisuda: I've just ordered this one: https://www.aliexpress.com/item/1005002011897796.html

                I'll see if this is more reliable. Have you seen any other USB-A/QC boards which could work?

                • naisuda on 20/08/2023 - 16:49

                  @gyrex: Nice, hopefully it's more reliable. I'll have a look later and see if there's any other options.

              • theguyrules on 21/08/2023 - 10:57

                @naisuda: Looks like I'll just be making the USB-C version

  • Joinkiee on 06/12/2023 - 20:07

    Would someone sell a USB-C version to me as my printers filler stepper motors arnt working 100% ATM? Would have to be a well made, 60w+ min

    Obvs $$

    Hi, what do you think if i use this adapter to convert ozito to milwaukee battery, than use another milwaukee usb adapter to get 65W charge?

    Thank you,

  • datscheap on 01/03/2024 - 21:17

    Just made the v2, running just the usb c board as the usb A one is still on its way from Ali.
    Its a cool thing, and well made. It fast charges my Xiaomi phone without issue, and I guess each 4ah battery is equiv to a 70-80000 powerbank?
    Anyway, thanks for sharing.
