Poundland's new 4000mAh power bank

There's been a bit of a tradition of Poundland power banks not quite meeting their capacity specs, but this one does hit the 4Ah mark.
The main features are USB-C charging at around 2A, a decent 2.5A output capability and the ability to put out 5V while also being charged to allow UPS (uninterruptible power supply) style functionality.
The circuit board has a standard power bank chip and also a combined control/MOSFET battery protection chip.
At £5 it's worth buying the unit for the bare lithium cell, but note that it's a standard type and not the high current type suited to drones and other high current applications.

It's always a bit of a thrill to watch Clive defuse a lithium battery bomb, almost never following his own advice to fully discharge it first. Acetone, isopropanol, and lighter fluid are fine for removing many types of sticky stuff, but I prefer heptane, which doesn't smell as bad as acetone and seems to work a little better than isopropanol. In the U.S., heptane is sold as an adhesive remover under the brand name Un-Du and as rubber cement thinner under the brand name Bestine. (Bestine is usually cheaper.) I wonder if whiskey, another flammable liquid after all, would work, although it does have better uses . . .

[@ohmbug10]

Oh no, don't use whiskey to remove adhesives. That's full out alcohol abuse. Drink the whiskey and you won't be bothered by the adhesive.

Delivering a supply while charging is such a great feature. I'm surprised that more units don't do that. It's so frustrating when this isn't possible. The other frustration I've come across when powering IoT devices is that, having laboured mightily to make your devices draw as little power as possible, power packs no longer recognise the power draw and switch off!

[@nigelh3253]

If you charge and also use the powerbank to power up phone at the same time, doesn't the output drop to the phone? So it's slower to charge up phone. Well that's my understanding. I'd rather charge up phone fully and then charge up powerbank fully. (Or vice versa)

4000 mAh is a small powerbank, and probably was at the time of review. Many phones now have a 5000 mAh battery, so allowing for losses, it wouldn't do a lot! But as usual and excellent review and enjoyed the circuit analysis.

I remember the first pound shops probably more than 30 years ago, how they made a REALLY big point of EVERYTHING being just a pound, the shop was completely plastered in anecdotal phrases as to how amazing the concept was, and "Yes, it's a pound!" Doesn't really work thesedays.

[@danwhiffen9235]

We had first discovered an equivalent store in Canada called dollarama about 20 years ago, and we kept asking the workers “is this only a dollar?”. They seemed annoyed. Our cart was full and the total was around 90$. It now should be called the 4 dollarama store.

[@dav1dbone]

@@danwhiffen9235 I know, as others have also pointed out, there can sell under a dollar or pound, several $/£ and anything in between. They used to get around the "pound rule" by offering 2/3/4 etc items for the money, probably with the way the economy was going a few years ago, volatility caused the reasonable retailers' sales model to become nonviable.

[@LitchKB]

At a guess - I'd say the absent resistor/transistor network is for optional Fast Charging capability - The standard USB port allows for 500mA, dedicated power ports are 1.5A, and then you've got the BC1.2 standard, and all the proprietary "standards" that each manufacturer had a go at creating. So short of actually using a dedicated USB charging "negotiator" (eg. TPS65988) you can just implement a certain resistor network which will statically advise the client (via the BC1.2 standard) of how much current it should be allowed to draw. The absent circuitry may well be for some proprietary support (eg. Apple, Samsung) - I know that early apple chargers were configured for 2.4A, which is rather similar to this device's output.

You were saying about the transistor pad Q1 not knowing what it's for - pretty sure that would be the 'turn off while charging' switch no?

[@antibrevity]

Many USB-C supplies will not provide power unless they can identify the client device and the pulldown resistors tell the host that it's a "dumb" 5V host. This has caused a fair amount of trouble for devices trying to simply move to a USB-C port without paying attention to the standard as older connectors did not need extra components. This has led some manufacturers to dread USB-C and continue using micro-USB for as long as the market would tolerate.

I kinda want one of those "OG" poundland power banks. I have been looking for a long time for a power bank that maintains a 5 volt output always. I have a few that will drop the voltage to about 4.5 volts and drop down to 4 then back to 4.5 every few seconds. Some stay on for like 5 minutes then turn off, some will stay on conditionally, and an old flashlight/usb charger will stay on always. (until the battery is depleted obviously.) EDIT: I forgot to add that a sufficient load (about 100-250 mA, depends on which one, tolerances probably) will "activate" the "weird" ones and will then maintain a stable 5 volt output. Is Poundland online too? and is it UK shipping only?

I believe that 5.1K resistor on the CC lines of the USB C connector are to tell the host device that it only communicates via USB 2 (or for power devices, signals that it uses USB 2 power delivery standards). If I'm not mistaken, tying both CC lines to ground via the same resistor is a violation of the spec. They should each have their own 5.1K resistor. This is the same design violation that was present in the initial run of the Raspberry Pi v4. There's a few articles online about the subject.

[@alexanderkupke920]

I would have bet on the CC line (Configuration Channel) for signaling Current capability (and cable orientation) as well, but I wonder about the Pinout, wouldn´t CC1 and CC2 be on Pin A5 or B5 respectively. But not sure about the pinout of that socket as well, also I can hardly imagine they crossed over pins within the socket. But you are right, if it is CC, each should have its own resistor. What makes me suspicious about the pinout of the socket as well though is also, that the outer connectors are actually wider than the others. with the housing of that socket beeing connected to ground, I would assume those are VBUS then where Power is transmitted, at least it would absolutely make sense to design those a tad beefier than the data pins. But those usually are Pin 4 and 9 in the socket. Unless of course this is actually a Power only socket, but then I wonder why they stil have 10 solder pins while actually 6 or 8 would be enough for those. If it was CC, I just looked up what the signaling was for the different currents. I think the in this case the power consumer measures the voltage between CC and ground to determine the current the source can provide. I think the lowest value would be 0.41 V, indicating either USB 2.0 500 mA or USB 3.0 900 mA, about 0.92 V would be 1.5 A and about 1.68 V would be the full 3 A. For those who wonder as I mentioned CC1 and CC2, those are the same pins on the different sides of the USB C plug. through this the device can recognize if both ends of the cable had been plugged in "straight" between possibly two USB C sockets, or if one side was twisted (the plug turned by 180 °)The "other" Pin would be used to power "active" cables (which is called VCONN).

I saw that too. It's inevitable. My power bank (completely different) doesn't go back together quite perfectly any more either. The inspiration for taking it apart in the first place some years ago was of course BC.

[@AnnaVannieuwenhuyse]

@@Chris_the_Muso it's the charm of doing it yourself 😉

@5:00 I find dental floss is brilliant for cutting through foam tape... I imagine it'll simplify unsticking those rubber pads too, particularly if iso isn't an option.

[@cheaterman49]

Smart!

[@dimitar4y]

if you damage it, use some aluminum foil tape! :> I do this frequently, no battery catched fire yet. Make sure you clean the surface and really squish the tape down, though. And then a layer of duct tape (the cloth stuff) to protect the fragile foil. I do this for batteries that have started ballooning. Puncture, de-gass and then seal the hole. Very important that you don't let air get in, so work fast!

*Yet*

[@dimitar4y]

@@TauCu Update: still hasn't caught fire, but the batteries that started gassing seem to gas regularly and drop in capacity. Apple and Samsung batteries are the #1 culprits.. Some self-destructing electrolyte in there, the battery becomes hard and stiff and loses flexibility.. Planned obsolescence hayo!

[@MrScotttraynor]

love the fact that you put in the measurements to take apart.. as battery boomskis arent not wanted ;)

[@Slikx666]

And that answers the question I was going to ask. Yes it can be used as a UPS. Thanks Clive. 👍😃

You said exactly what I was thinking! I think I may use one of these for an android powered GPS vehicle tracker.

He's so careful with the battery, watch a cellphone repare shop replace an iPhone battery.

[@Anvilshock]

Well, it's being replaced, innit?

[@HiddenWindshield]

@@Anvilshock Yeah, but the phone itself isn't. And if they accidentally damage the battery, I kind of doubt they'd have enough time to get the battery out before the whole thing bursts into flames.

[@idont3282]

@@HiddenWindshield You actually have time to remove it, speaking from experience

[@cameronlevers231]

Most of the energy in a lithium battery is in the charge that's why he recommends discharging the battery. His battery was brand new and fully charged

[@ElmerFuddGun]

Actually you should try to pry batteries like this with more than one "pry" bar at a time to prevent damage. Or use a wider pry bar again to help distribute the pressure.

[@SurajGrewal]

Oh the lengths we have to go through to get these cells. Imagine if the simply sold it to us.

[@DangerousPictures]

I always use old gift cards to pry out cells. they are cheap, flexible, non conductive and they apply force over a wider area

[@kitecattestecke2303]

"Payback" cards or old debit cards are ideal indeed... That's what we use in Europe Also ideal for removing car trim or to scrape off glue

[@rjamsbury1]

They're useful for all sorts 👍

Why oh why oh why have I just spent 10 mins of my life watching someone perform detective work on a Poundland power cell? Love it Clive . Thank you for utterly useless but completely fascinating insight into something I has NO idea would be interesting. This is what KZbin good for.. giving entertaining people a chance to shine in weird and wonderful worlds!

[@rogerhargreaves2272]

Great powerbank. The old version holding the 5v output was handy for my string lights as it kept the timer on so you didn’t have to switch them on every night. Great video Clive, thank you.
