Came to post this. If you're struggling to find something, a USB A to USB C cable is always handy with a power bank and are ~$6 during this sale. Here's a link to PBTech's list of cables: https://www.pbtech.co.nz/category/peripherals/cables/usb-c-c…
Got one, thanks OP.
I own this, great bank - fast charging feature.
Shame usb-c only for input
Note: You can't charge your phone with the usb c port. It will charge the battery bank only.
that sucks, its not a true usb c connection,
I know, I bought it thinking that it had usb c pd but I was dissapointed. Still a good power bank though, it charges quite fast
Thanks for the heads up
I've got two of these from the previous sales, great power bank at such a great price.
Bought last year. It was faulty and PBTech replaced it with no issues. Works fine now.
Or this cable https://www.pbtech.co.nz/product/CABUNI4049/Unitek-C4049RD-3… or this bulb for filler https://www.pbtech.co.nz/product/BULMIX26688/Xiaomi-WiFi-LED…
Bought that 3in1 cable few months ago and it's crap. The charge rate is too slow. It will take ages to charge few %. Had to replace with a $2 cable from dollar store which was not great quality but better than this $12 cable. Submitted a review but they never published it.
I wish your response arrived a bit earlier, its too late now :(
https://www.pbtech.co.nz/product/BAPMIX26922/Xiaomi-Redmi-20… heres one with double the capacity for $11 more, will also get you to reach the $20 minimum for free shipping. I haven't used this one but it seems better since it has fast charging?
I like how you can charge this and power something else at the same time!
This should be great as a gift under $20 for Christmas.
This is a great battery bank and it does supply a good honest 2.4A out to a single device.
I often use this to power my Google Home Mini speaker outdoors and it'll go all day long.Drawbacks are as pointed out the USB C is not an output.
Also when plugging in a second device the first device will be interrupted for a split second. That won't bother you charging phones. But If like me you are running a device that has no battery of it's own such as a Google Home Mini, you can expect it to power off quickly before being powered up again immediately.
Came looking for comments like these. I was wondering, do you know if the source input power is interrupted (always charging) does the output ports get interrupted even momentarily? I was thinking of getting a couple of these as inline Raspberry Pi UPS's for my Pi-Holes but if the outputs are interrupted when the source loses power then I'll have to keep looking.
Hey, my comment was about the output being interrupted when a 2nd output device is introduced.
But seeing as you are a fellow Raspberry Pi user i just went an tested running a Pi then introducing input to the battery. It does interrupt it, so it's not going to be a solution as a Raspberry Pi UPS.
Good to know, thanks for testing it!
I own one of these, just order another one, I find it excellent!
sorry bit out of topic. Could someone recommend a USB-A to USB-C cable please that could make use of this charger. Mine just broke and would like to buy one urgently. Very hesistant to decide from the pbtech reviews as I bought one few months ago which showed great reviews and turned out to be crap.
Try Amazon. If not in hurry get baseus brand from Aliexpress.

Thank you. Will order a spare one from amazon or aliexpress.
Perhaps a dumb question from me - are not all USB A to USB C cables created the same? I have several from phones, tablets, etc and just use them interchangeably. Is that wrong? 🤔
Nothing wrong in using them interchangeably if you are happy with its charge speed.
A good cable should use the maximum potential of the charger.
The cable I'm referring to was charging at around 100mA current. At this rate it will take 10hrs for my phone to fully charge. But the other cable was charging closer to 1500mA using the same charger. I believe my charger supports a max 1500mA current.
Tried a $2 cable from dollar shop and it was charging around 500mA. But the cable didn't last long.Interesting - good to know - thanks
Pretty much all properly made USB cables should be interchangeable although some charging standards e.g. OnePlus/Oppo's VOOC require proprietary cables. Using these cables on other devices should be fine, and using non VOOC cables on such a device is also fine albeit may result in slow charging speeds. Last I looked I wasn't able to work out for sure but I don't think Huawei's supercharge (which is a similar ~5A charging standard) actually requires a proprietary cable. However most cables can't handle 5A so I assume the phone detects the voltage drop is too high and drops charging speeds.
Anyway one key point. Standards compliant USB A to USB C cable should have a 56k ohm pull up resistor https://www.theguardian.com/technology/2016/mar/30/amazon-cl… and https://www.reddit.com/r/GooglePixel/wiki/officialguide/usbc… which will tell the charging device the maximum current is 500mA. This may seem low, but it the device and charger want to signal a higher current or voltage they should use USB-PD or alternatively some proprietary method of doing so. (I know most standards promoters also dislike proprietary methods and there is some risk or conflict or the device being confused. But at least the device isn't always told to do something it shouldn't.)
The problem with making a cable in a non standards compliant way is you risk telling the device it can safely do something it cannot do so. It's entirely possible for a USB-A port to only be able to safely supply 500mA but the device may incorrectly think it can draw 1500mA or even 3000mA from the port. Unfortunately in part because cheap Chinese manufacturers tend to be bad at following standards and probably also in part because many chargers, power banks etc can supply at 1500mA or higher there are many incorrectly made cables out there. Attention in ~2016 did push the better ones to improve still I'm sure you'll still find many that aren't correctly made. And it's not something easy for the average user to test.
Indeed that gets back to my earlier point, even with the attention in 2016, most users still didn't know then or now. And so if cable A gets a decent charge speed when their device is connected to powerbank X and cable B a poor charge speed, they may assume cable A is well made and cable B is poorly made. In reality it could easily be that cable B is well made with decent enough wire gauge to handle even 5A. However the device does not charge fast with such a cable because the powerbank doesn't tell the device it can charge faster than 500mA in a way it understands. (Note I'm not suggesting this is Shami's experience. It's easily possible the difference in charging speeds was because of some proprietary signalling method.)
Separate to charging, a USB A to USB C can either be SuperSpeed or not. You should generally be able to tell by looking for the extra pins in the USB A plug. To be clear this won't affect charging but may affect transfer speeds when the phone is connected to a computer etc.
Thanks for the detailed response - I'm lost for words ;)
I realised this should power the HomePod Mini to make it portable. :)
