What do you think of these claims?
Holy Cruppp! That is extremely quick! Based on the website 18 minutes for a full recharge is very, berry, barry impressive! Graphene technology.
Woah. That’s fast. I wonder if anyone can vouch for these claims though…
If it is true, then that is amazing. Of course to have that inside our devices would be even better.
Tell you what a Fusion 5000 which recharges your phone in 18 minutes, then recharges itself in 18 minutes, then that would make me impressed.
Assuming (as they do not state) 3.7V so is a 18.5Wh capacity, at 45W which is the maximum stated ingest power, you get 24 minutes, not 18 minutes.
So that “as little as” 18 minutes, I think it lacks some clarity of what % empty to % full. Currently a lot of fast charging technology is claiming to a less than full fast charge as it’s easier to charge faster from empty than it is to full.
Their claim: Thanks to Power Delivery Input (60W) and Super Low internal Resistance Graphene Composite Battery, the time for a full recharge takes as little as 18 mins, which is 13x faster than others!.
So the input rating is 20V/3a whuch is 60w input not 45.
And thus is what I was talking about in the Tesla made a new battery breakthrough. The use if Graphene can be used as a super capacitor and can be rightly charged just as fast.
You are correct, my error, I was looking at output not input.
Woooowwww that seriously sounds absurd !! 5K in 18 mins a super fast! Wonder how the life of the battery will be over time though
I think they are using supercapacitors inside that battery in addition to regular li-ion thus calling it composite battery.
Assuming 5000 mAh capacity (@ 3.7V nominal voltage) it has a 5Ah x 3.7V = 18.5 Wh capacity.
To fill all this capacity in 18 min (0.30 hr) this battery has to recharge at 61.67 Watts (approx. 60 W).
I guess they are claiming that this battery is taking in 60 Watt (20 V x 3 A) charge. Bottom line is that you cannot charge a 3.7 V li-ion battery with 20 V charging voltage.
For a 5000 mAh capacity this thing is huge. I’m very sure that there are a bunch of supercapacitors inside that are connected in series to balance out the 20 V input (leaving about 4.2V for li-ion) and these supercapacitors are then charging the li-ion battery indirectly.
Alternatively, they can put 4 or 5 li-ions in series (with balancing circuit) to take in 20 V at 3 A so each cell will see about 4.2V input at 1-1.5A. Incorporation of graphene on li-ion anode will help with high charge/discharge of li-ion thus increased charging rate.
Either way, they are definitely using supercapacitors in addition to li-ions in this powerbank. 8000 cycle life with li-ion is not possible unless paired with supercapacitors.
Very sure they are using this CellsX battery (5 in series with balancing circuit). You can see that even at 5A charging current this 1 cell with take an hour to fully charge.
Like I mentioned, super capacitor you just explained it much better
Absolutely you are 100% correct with supercapacitor
19 minutes for 10000 mAh exist now, making Anker seem slow
Seems Graphene enhanced batteries are about 30% more expensive, so thinking out loud, I’d guess they’d make the most sense in a few situations:
- High end expensive phones where the battery part of the cost is a small % of total cost and so it being 30% more would add a tiny % to the total cost but give much faster charging times, so “flagship” phones.
- small batteries in the likes of wireless earbuds where the absolute cost of Graphene in a small device will be small, and be a small % of total cost.
- combining these two above you can imagine a wireless recharging flagship phone being itself able to be recharged quickly and it can wirelessly recharge buds quickly using a small amount of its stored energy.
I don’t see an initial logical reason to have in other products - do you?
Anker doesn’t make its own cells, e.g. they seem to be using the LG cells in their “redux” products, so really Anker would buy cells from someone who is licensed to make Graphene enhanced technology, so we should be able to see Anker Graphene portable chargers… within the next year?
I don’t know how mission critical it would be to me personally that my powerbank could charge that quick but getting 8000 cycles would make it worth it, now it just need to be smaller
Phones go through far more power cycles than portable chargers, on average, and a phone is a lot more expensive, so it makes sense to put them in high end phones. But say if Anker made a 10000mAh which could recharge fast, both phone and Powercore needing 45W charger then it would drive a fresh wave of investments.
About half my phones die from battery aging.
It takes over 8 hours to fully charge my PowerCore 10000 PD using a standard 2.4A charger.
It takes almost 4 hours to fully charge it using an 18W PD charger.
18 minutes to charge 5000? 19 minutes to charge 10000? Wow, just wow!!! Although in the video posted by @professor, it took about 26 minutes to get to 100%. But the $140 price tag is just not worth it for me, even with the included 100W charger. I’d still rather get more capacity than speed. Something like this (currently available with $10 coupon, so only $108.99:
The costs are coming down, it’s coming out about 30% more expensive for Graphene batteries. You do need higher end chipsets to do the charging but these are dropping in cost. Currently a 60W charger is about $30 more than 10W.
So what I expect we’ll see first is flagship phones in the $1000+ range having them first as the % impact is least, of the order of 10% higher phone cost to bring recharge times down from 2hr to say 20 min.
Personally in portable chargers, I won’t buy at much more than a few $ , which will happen eventually.
Currently I own a 10000mAh Slim and non-Slim PD, each charge in 3.3h and combined cost me $35 and a dual 18W charge cost me $30 (now I see for $21) so for about $55-$60 I get 3.3hr recharge 20mAh. To pay $110 for 27Ah to recharge in 3.3hr is itself already a premium I’ve chosen to not pay, roughly double the cost.
Smaller portable chargers are used more as they are pocketable. For longer trips you can carry two.
So I see you won’t be able to sell in volume expensive portable chargers, but I do see the technology coming to high end phones in 2020/1 and as costs drop to then portable chargers 2022+
I’ve been trying to find out if that powerbank would actually charge a Galaxy Note 10 Plus at 25W or just 15W
I know it won’t do 45W as Samsung use a different standard for that but if it did 25W I think I would get one.
Buy a USB meter.
The scenarios where paying $$$ for a portable charger is fairly niche, to the degree I think many reading this don’t need to pay it.
A laptop charger needs to:
- run the screen
- run the cpu, other parts
- recharge its internal battery
So a laptop’s quoted power needs are usually the sum of these, so say 45W laptop charger can recharge the laptop when the laptop is being continually used, it may well spend many times needing a lot less. You’ll never know until you buy a USB meter and look at consumption over time.
So say 30W is enough to power the screen + cpu but not enough to also recharge the internal battery while laptop is used, well then you’re talking the portable 30W charger will hold the internal laptop battery at its current level until you stop using the laptop and then screen off will then allow internal laptop battery to then recharge.
USB cables are not all equal. I tested some cables last week on my 18W laptop (Android tablet + keyboard) and one cable was giving 4W but a different cable was giving 10W from a 12W port of portable charger. In general, shorter cables are more likely to be performing better. Longer USB cables make sense to pair with wall chargers as the wall charger can more cheaply be higher wattage to fight a bad longer cable, while shorter cables make sense for portable chargers who don’t have to stretch to a wall socket but right next to your device.
Phones have more of a thermal issue as they are smaller so there’s slower heat dissipation, so they usually thermally throttle their recharge. But with graphene internal phone cells making more heat, will disproportionately benefit as you can then be using the phone while it is being recharged.
