According to the spec's,
"Usually a power bank could supply 60%-70% battery to other devices. Around 30-40% of the capacity is lost in circuit heat and voltage conversions. So a fully charged INIU 10,500mAh B6 can offer 6100-6300 mAh to your devices."
Is this really the case for other power banks?
Yes I have a charmast brand 10,000 mah pack and I get much less charge than the 10k capacity of the pack. About 7000 seems about right to what I can get
Yes.
Power banks generally use 3.7V batteries, but output 5V or more, so available mAh drops accordingly.
See the review on Choice https://www.choice.com.au/electronics-and-technology/phones/….
Average capacity of a 10000mAh power bank is around 6200mAh at 5V.
No, its wrong. Operating voltage of lithium ion battery cells inside the power bank is about 3.7V while traditional USB interface is 5V. Thats why 10000mAh at 3.7V ~ 7.4mAh at 5V. The convertion lost is just about 5 to 10% in good powerbank. In short, the power it provides in watts (Ah x V) is about 5 to 10% less, not 30%.
In short, after voltage conversion and conversion loss, it's 30 to 35% less.
Average capacity of a 10000mAh power bank is around 6200mAh at 5V (what USB / your phone is at).
Thats why 10000mAh at 3.7V ~ 7.4mAh at 5V
Which is a numerical drop of 26% mAh
the power it provides in watts (Ah x V) is about 5 to 10% less, not 30%
The Watts are actually the same, ie 10000 x 3.7 = 7400 x 5.
According your own numbers the difference mAh available to use at 5V is 26% lower than the 10000mAh listed on the tin becasue it is at 3.7V. And assuming some heat losses in the transformer and you're pretty close to 30%.
Mate, power is measured by watts, not ampere or volt. Since the wattage is pretty much the same 10000x 3.7 vs 7400x5. You cannot say it lose 30% of its power because of the mAh diff.
You cannot say it lose 30% of its power
And at no point did I say that. I even specifically said that the power is the same "The Watts are actually the same".
Can you read?
@1st-Amendment: Can you read the whole sentence?
And explain what you said: "According your own numbers the difference mAh available to use at 5V is 26% lower than the 10000mAh listed on the tin becasue it is at 3.7V. And assuming some heat losses in the transformer and you're pretty close to 30%."
Can you read the whole sentence?
Sure can, can you? Clearly not since you even quoted me saying mAh (current) not power, yet somehow still managed to confuse yourself..
Stay in school kids…
mAh is current to you
Capacity to produce current, as opposed to power, which you got confused with and had to be corrected multiple times…
Shouldn't waste time on you.
You got that right. Yet here you are, wasting your time… amazing logic…
I like this one has built in light which while weak is useful
These like iptv subs, I can't resist a deal on them.
Can you please recommend me some subs?
Thanks OP just ordered one, should come in handy for next power outage
Thanks ordered one.
Phone book size
Any idea how long it takes to charge the power bank?
I bought one of these a while ago and I'm not particularly impressed by it.
The 10,000mAh advertising is borderline deception. It charges devices attached to it, yes- but I might get a useful charge of 6,000 mAh (not sure).
And yeah I know- all powerbank manufacturers probably use the same measurement system so it's certainly not the odd one out. But if you want to charge iPads and the like you'd probably want a 20,000 mAh unit.
The 10,000mAh advertising is borderline deception.
Only if you didn't pay attention in school. From memory Ohm's Law is part of year 9 curriculum.
It's back for $18.99
Cheers! Got one. It's annoying how it's only 1 per account and I just signed up for the 3 month free prime trial on my Westpac debit card. Wanted to get 2.
INUI vs Zyron mini? Is anyone better than the other apart from the charging speed of 18w vs 22.5w.
My Samsung will get charged on 15w only with both anyways
You can charge your laptop with USB C with 22.5w for emergency situations
anyone not seeing the coupon?
Yeah disappeared for me now
Thanks OP. Ordered last night and it just arrived. So fast. Good size, quite slim and even comes with built-in torch light and a phone holder so you can watch videos while charging. Good value product
Is that what that slide out thingy is for? (I don't read manuals).
Gave it a test this afternoon - charged my phone from 10% to 100% using about 32% of the powerbank capacity.
Yes, the slide thing is for holding the phone horizontally while its charging.
To turn on and off the torch light, you double click the button
Deal is back again
Clip both the 40% off and 10% off coupons to get the price in title
Available again with a single 50% couple, and better yet, to those that have already purchased before with the 40+10% coupons
Thanks op, was able to get this today at 50% off and 10% off with the code - brought it down to $15.19
$15 unobtainable deal this morning and removed for some reason.
