Just be aware there is an identical model but with quick charge 3.0. I have this original one and wanted 3.0 and almost bough this again as the image is almost the same.

Got you to 107 brutas, you're welcome
Sounds good, just need one with USB c charging!
Can't tell if this has pass through, i.e. can be charged up itself while simultaneously charging a device.
Damn, just ordered the other one, 10k mah for £9
2 inputs? That's a new one on me!

I had a much much older model from them which did have pass through
So most likely this will too

I own three of these (QC3.0 models), one downside is they don't have quick charge themselves they take overnight to charge themselves. but they do quick charge , most other things very well. I bought them back when Pokemon go was a big deal for the kids but we used them most days now for other things too, im about due to start thinking about replacing them actually.

I am still not sure about dual charging, why Amps usually drops down..? For example charging one device I can have more amps (bit faster) than when charging two devices at once

There is a buck regulator circuit stepping up the voltage (lithium cells are 4.2v full and 3.5v when discharged) this circuit has to take this variable lower voltage and step it up to a stable 5v for your USB item to charge from. This circuit is usually the limitation to charging current. It's happy to go up to 3.4a either on one output or shared between 2 but cannot provide more current than this without the voltage dropping down.

A powerbank or mains charger will have a maximum charge rating in amps. If you only have one device connected the powerbank will charge it at the maximum safe current. Smartphones are usually lower than tablets as they have smaller battery capacities.

When you are charging two devices at the same time then the charge current is shared and so will obviously be lower than what is possible when only one device is connected. Two tablets being charged at once for example.

I've got it.

No passthrough.
Do you have to press the power button to turn it on?

Will it allowuninterruptedpass-through?

I am looking at doing a permanant install with one of these to maintain my dashcam for parked recording. So the powerbank charges while the car is on, and powers the dashcam while the car is off, with no interruptions and no need to mess with plugs, etc.

I did buy the teknet one with the same capacity, and it does do pass through, but when switching from charging to non-charging, it seems to have some sort of cutoff, you have to physically unplug/plug back in the dashcam to use the power.

So it need to be uninterrupted.
What is the benefit of a powerbank that offers USB-C with Power Delivery compared to a different model without Power Delivery?

Some computer monitors for example have USB-C ports with Power Delivery that can power connected peripherals up to say 100w. I see the benefit in not having to have a separate power adaptor for the peripheral in that scenario but can’t get my head round why it is needed in a powerbank because if a USB-C device is connected it should recharge it just like any other device. Or is it so you can use the USB-C device at the same time as it is being charged up by the powerbank?
Highly recommended power bank!

If anything as good as my previous version of this, can’t go wrong for this price!
Had it for over two years and still holds plenty of charge- you can charge iphone/other smartphone very quickly from any of the 2 outputs!
Excellent for camping and such!
Previous version was slightly better as had torch which made it even more useful for camping;)

Yes you have to press the power button or it wont start charging, and if it fully charegs a device it turns off and requires the button to be pressed again, so its not gogin to work with your dashcam.

How does this compare as I was looking at this one? A lot inferior?

Interested in why you are thinking about replacing them, are they not holding much charge anymore or are you just looking to upgrade capacity?

Power Delivery if helpful in power hungry devices like usb charged laptops. Regular powerbanks won't give out charge fast enough.
Ah, for use with laptops. That makes sense.

Thanks.
Hi Guys. Thinking about buying a power bank. For my MacBook Pro and iPhones. Which power bank would you recommend for fast charging and compatible with various devices. And pretty portable too.

Many thanks in advance. 🙏🏼

Never mind. Found one that works. Thanks
Fun story, I had an Aukey 20000mAh power bank (PB-17) that had lasted me well over the years.

Coming back from China last week I was stopped at the security scanners.

Long story short, had to go to the supervisor's desk, they refused to let me take the power bank onto the plane because the size of the battery was not listed on the device itself.

Not something that I'd encountered the other times I'd flown, but perhaps something to bear in mind.
Sorry, can someone pls suggest, how does this compare with -

Todamay Power Bank, Portable Charger 26800mAh Fast Charge with 3 Inputs & 2 Outputs Ultra Compact External Battery Pack with LCD Digital Display for Smartphones Tablets and More

Yep, same happened to me in Finland. My trusty Easy-Acc 20k battery is now in a skip somewhere in the Arctic circle.

I've replaced it with a slimline Charmast one, bigger capacity bit looks smaller so will hopefully be ignored.....
Would this be more than good enough for on holiday using 2x SAMSUNG s8 and a bluetooth speaker ??
