Looks like a good price on this powerbank :)
Verbatim Portable USB Power Pack Charger - 3500mAh $7
thanks got one it will go with the $3 one i got there last week.
Only store with stock in VIC seems to be Corio (Geelong)
Thanks… just bought the last unit at West Perth :)
I'm pretty unknowing with USB power banks and their stats and what they mean exactly. The price is nice, but what exactly can this do for me with it being 3500mAh? Is that good for charging a mobile phone at a good rate, or any other uses or more just a mediocre last minute, can't use in-car charger type deal of a item?
In layman's terms, mAh means capacity, and not charge rate, so this pbank can hold 3500 milli amp hours. For your comparison, modern phones; iPhone 6S - 1715mAh, Samsung S7 - 3000 mah, xiamo redmi note 3 - 4000mah etc. so 'theoretically' you'd be able to squeeze out almost two full charge cycles out into an iPhone, but we all know that won't happen due to heat loss etc
I rock an Xperia Z5, so from my quick searching that's 2900mAh, so I would get a bit over one full charge then from this bank. So I guess that's not too bad. But as you said, capacity, and not charge rate. What do I look for to find out how well it does in that area?
that would be 'output current' rating in amps - it appears this one is 1A at 5V, which is pretty standard I believe, so it'd be similar to your wall Z5 charger.
remember current/amps denotes the rate, that's why iPad chargers are so often used as their adapters have 2.1Amp vs iPhone 1Amp adapters, allowing a quicker charge.
@KeplersLaws: I see I see. Thanks for the info! I shall begin my hunt to try find the best suitable powerbank for my needs :)
@SySalem:
Actually your phone might have some kinda space-age fast charging feature that I didn't account for. but yeah 1A is pretty standard, shouldn't be too bad
@KeplersLaws: That's a good point. With his own wall charger, I just set and forget while I nap, but with my coming travellings starting soon, I thought something like this might be handy. Local store says they have some in stock so will squiz it out tomorrow and see how it comes. Worse case, $7 unit until something better comes along isn't bad. Thanks again for the help!
This battery pack contains a 3.5Ah lithium cell. Assuming the standard lithium ion voltage of 3.7v, this pack contains 12.95 watt hours of power (that is 3.5*3.7). This is approx twice the capacity of a small smart phone. However there are power losses in the conversion to 5 volt, conversion back to 3.X volt and heat generated by charging.
Also the charge rate is a maximum of 5 watts which is fairly slow compared to newer 10 watt power packs (which can charge a tablet).
hmm yeah you're right, i had a look at xiaomi's pbanks and they're 3.6A, which is quite a bit more.
3.6A total, max of 2.1A per port.
Its kind of sad that we can't just buy a spare phone battery and swap them any more. I blame Apple, and sheep like Samsung who copy them.
Android and IOS are great, but I do miss Nokia hardware.
I use a redmi note 2 and have a spare battery :) when it runs low I can either use my power bank of swap the battery out for a new one :)
My ZTE Qlux has a removable battery as well.
In fact every mobile phone I have ever owned has had a removable battery, I wouldn't be so silly as to buy one that wasn't.
Its kind of sad that we can't just buy a spare phone battery and swap them any more
A spare phone battery powers ONE phone.
A portable power bank can power almost ANY item that uses USB. You can use it for accessory lights, fans, and all manner of other devices apart from phones.
I have no idea why anybody would want to be able to swap their phone battery - it's so cumbersome! A power bank is infinitely better.
My Samsung phone has a changeable battery and I have a spare… and I've NEVER swapped it :-)
I accidentally added 2 to my cart. They came up as separate items. I was going to remove one as I only wanted one, but my housemate wants one anyway so I went ahead and bought both. I added one to my cart, logged into my account, then thought I didn't have one and added one to my cart again. After checking out and purchasing 2 of them, I tried to reproduce it and somehow ended up with 3 in my cart by logging in and out of my account a couple of times and adding to my cart while logged in and not.
I don't know how it's going to turn out. I'm not even sure they have 2 in stock as it's now saying the store is out of stock. I was able to reproduce it with other items as well.

You can probably create multiple orders. I'm not sure if they will honour both when you go to pick them up? Then again, they may not with this either.
I was a little concerned because it only showed one of them in the email saying they were ready for pickup, but it was fine and both were there when I went to pick them up.
not at punchbowl or sydney [nsw]
That is less than the battery capacity of some smartphones.
No, it's not. How many phones have a battery that large?
In any case, it still contains enough capacity for a significant "top up", and will even keep a tablet running for a few hours.
My Redmi Note 3 has 4050mah.
I hear the echo of slow clapping.
@llama: So you claim there aren't any phones with higher capacity than 3500mah, and you just got proven wrong with one example. Your slow clapping is meant to be your refutation?
I honestly don't care that you feel the need to "prove me wrong". If your phone has 4050mAh, then yours is obviously bigger than everyone else's.
In fact, I'm sure somebody could find a car battery that also has a larger capacity than this small, light and compact power bank. However that would be missing the whole point of the product, wouldn't it?
@llama:
I said: That is less than the battery capacity of some smartphones.
You said: No, it's not.
That would mean that there does not exist at least some phones with a bigger battery than it. You were proven factually wrong with an example and your best comeback was "slow clap".
I honestly don't care that you feel the need to "prove me wrong"
I honestly don't care that you don't care. If you're going to make factually wrong statements and then brush it off with slow claps, correcting you is justified.
In fact, I'm sure somebody could find a car battery that also has a larger capacity than this small, light and compact power bank. However that would be missing the whole point of the product, wouldn't it?
If it was intended to charge car batteries, this would be a relevant point. It isn't. So it's just another attempt to brush off an error as inconsequential. Why did you even bother to 'correct' me if you didn't at least somewhat care about being right or wrong?
If your phone has 4050mAh, then yours is obviously bigger than everyone else's.
It's not about being bigger than everyone else's (another factual error). It's merely stating a fact. Some phones have a bigger capacity than this battery. Most respectable powerbanks are bigger than phone batteries. Verbatim actually sells power banks with even smaller capacity than this.
Here's one with 2200mAh, and supposedly has a recommended retail price of $48. Just embarrassing.
You were proven factually wrong with an example
Well yes, I know that YOU PROVED ME WRONG. I freely and sincerely admit it - I made a mistake. All liability has been accepted, and all admissions of fault have been made. Thankfully this thread now only contains 100% factually correct sentences! The community is satisfied, and proud of those who fight the good fight.
You said: No, it's not.
I said, You said, He said, She said! I can assure you that if I was able, I would edit those three words that you are obsessing about. However it's no longer possible due to the replies. So, let me edit it here and now…
ORIGINAL: "No, it's not. How many phones have a battery that large?"
CHANGE TO: "Yeah, so what? How many phones have a battery that large?"
If you're going to make factually wrong statements and then brush it off with slow claps
Sometimes I notice people who exhibit a distinct tendency to take written words extremely literally. My various sarcastic replies have obviously failed to clarify the simple fact that I never wrote those 3 words as "absolute facts". Those 3 words were simply a short lead in to the words that follow - specifically my second paragraph, which said:
"In any case, it still contains enough capacity for a significant "top up", and will even keep a tablet running for a few hours"
Capisce?
$30 to post two. Jam it, Harv.
Ordered one op.. Oconnor and west perth are the only stores available for pick up in WA..
