I had a few Parkside X20V batteries sitting around and started thinking — why not use one of them as a portable power source?
So I designed and 3D printed this little USB charging hub.
It has 2× USB-A and 2× USB-C, and the SW3518 module allows USB-C PD charging for compatible devices — even laptops.
It supports PD 3.0, PPS, QC4.0+ and QC3.0, so it can handle much more than just charging a phone.
Now one of my Parkside batteries can come in handy not only for power tools, but also when I need USB power in the workshop, car or outdoors. 🔋⚡
Honestly, I wasn’t sure how useful it would be until I tried it. 😄

Now it probably isnt very good but for 7.5 NZD ( 4.41 USD ) what could go wrong

Just wanted to share a pic of this cute lil power bank I got recently. What you guys think?

Hey guys! I recently bought a laptop with a very power hungry processor. This makes it so when someone would normally get 8-7 hours of battery life with a weaker cpu, I would get somewhere around 4-5 hours doing the same task. Ive come to the conclusion of buying a powerbank for my laptop, but have trouble deciding between one or the other. Since they are both essentially the same price, which one would:

-Last me longer
-regulate heat better
-Charge more efficiently

Thanks,

Any recommendations to this type of powerbank? I'm a big fan of powerbank with built in ac outlet so you don't need to spend more just to buy an extra cable or brick. Just plug the powerbank and charge itself. Also you can charge your phone while charging the powerbank. Anybody knows other powerbanks like this in 10K mah up with 65W charge speed? I need a spare.

Design: Compact slate blue matte finish, comfortable in hand and pocket-friendly. The little paw print logo is a nice quirky touch that sets it apart from the usual plain black power banks.

Capacity/Output: Rated 10000mAh with dual cell capacity (5000mAh x2), max output of 45W. Good balance between capacity and portability, enough for a couple of full phone charges without adding much bulk.

Ports: Comes with USB-A, USB-C, and a built-in braided cable that loops back into the unit itself, so you don't need to carry a separate cable. Genuinely convenient for travel.

Fast Charging: Supports PD/QC fast charging (up to 45W max output), so it handles modern phones without the painfully slow trickle charge older banks give you.

Build quality: Feels sturdy despite the compact size, no creaking or flex when gripped firmly. The built-in cable loop feels secure and doesn't dangle loosely.

Bottom line: A well-rounded, no-fuss power bank with a genuinely useful built-in cable and solid fast-charging output. Great for anyone tired of forgetting a charging cable at home.

Para kasing I am not getting my money's worth. Ang bilis niya malowbat. Ang bilis din naman niya marecharge pag china-charge ko siya.

I bought this for rainy season power cut emergencies, for my laptop na rin, pero parang mas matagal pa malowbat yung Romoss ko na ilang years ko na rin ginagamit.

Overrated lang ba talaga ang Anker? Years ago may binili din akong Anker na magnetic para sa iphone ko, hindi niya napupuno yung iphone 14pm ko and ilang months lang nasira na rin.

Kumusta ang may mga Anker powerbank dito?

Hi,

My sister gifted me her broken power bank. It can still be charged, but discharging wont't work because the USB ports are worn out. Since the cell still seems to be good, Ithought it would be a nice little project to build my one. However, I am relatively new to this and not sure about the right circuit. I want to use a pre-build one from eBay and found the following, which seems pretty fancy.

The cell I am using is a 10,000 mAh 3.7 V from a GREPRO hyg035.

It uses the IP5219 ic for charging/ discarging.

My question would be if this is a good match or if it will burn down my house.

Maybe someone can give a good feedback for this thx :3

Not really a power bank person, but I travel with a MacBook Pro a few times a year and I'm tired of hunting for outlets at airports.

Looking at a 25,000mAh/100W one. It probably won't fully charge a laptop from empty, but for work trips that's not really the point, being able to top off the laptop or phone without hunting for an outlet at the gate seems worth it.

For anyone using something this size with a laptop, what does it realistically get you?
