Does the powercore with USB c charge the new spectre x360?

#5

Hi,

@Jack_Matthias, have you successfully charged the HP spectre x360 with the powercore+ battery?
I’ll wait your feedback to buy one :slight_smile:
Thanks,

I charge my 2016 MacBook Pro which is USB c

#7

Yeah, but this HP USB C connector seems to be specific for power.
It might not work for charging the HP but the HP might be able to charge the PowerCore+.
This is why I’m asking a confirmation, don’t want to buy it if it doesn’t do the job :frowning:

#8

Hi Guys,

No one have been able to try the powercore+ with the new HP spectre?
I’m not sure this might be a good buy if it’s not working as expected…

Thanks

So if I understand correctly you already bought the HP and ask about buying the Poercore+ USBC?

Is there a default lower power input to the HP of USB2 2A 5V? If so then focus on that. That is what I do. Use recharging defensively as in plug in Powrcore as soon as you can like when not moving, to slow the drain of HP internal battery. You’re likely to find that is sufficient to extend device battery life. 2A is better than nothing.

Hi,

Yes, I already have the HP Spectre and was looking for a nomad way to charge it, this is why I’m looking at the powercore+

Not really sure what you mean by a default lower power input.
The thing is I’m not sure HP allow external charge beside their own power supply.
People are saying the old model doesn’t allow power supply other than HP so no way an external battery will do the job.
It seems to be different with the new one, but not sure.

I guess I’ll have to give it a try and tell you guys if that’s OK or not.

#11

I read it will slow charge. So was is it’s lower level? Defensive charging works well.

#12

Thanks.
I’ve just bought one, I’ll let you know if it works once I got it :wink:

#13

Guys,

I’m half way to happiness…
This is charging the HP but only when this one is in standby mode or power off.
When it’s power on, the HP indicates it will charge slowly but actually, it’s not, battery life is just decreasing much slower.
It will extend battery life but not charge it.
But this is very practical if you travel from point A to B and want to charge a little your computer on your way :wink:

Hope this help

mg1,1) When the 13" kaby lake x360 is power off or standby and its battery is near empty, how long does it take to charge from the Powercore+? 2) How many charges from a fully-charged Powercore+ (e.g., 1.5)? 3) What do you use to charge the Powercore+ and how long does it take to charge? 4) Have you learned anything more since your last post (Jan 30 17)?W

#15

Jack_Matthias how well does it charge a mac book pro?

#16

The PowerCore+ 20100 will either not charge or charge the MPB extremely slow. However, Anker’s PowerCore+ 26800 with PD will charge it. Even so, it won’t be as fast as the charger that came with your MacBook, but quite a bit faster than the 20100, that’s if it even charges it at all.

#17

They should step up their game then to have all USB-C laptops able to be charged using a battery bank

#18

Anker’s past has proven that they are slow atadipting and maximizing the potential of new technologies…

#19

Is that also why they are on average more reliable?

#20

More reliable and generally higher quality when compared to competitors. There are few if any capable USB-C PD power banks out there (around 30W max). I think we’ve reached the point where the traditional 18650 cells with high capacity are approaching their limits, hence the switch to LiPo batteries that operate at a higher voltage and give a slightly better capacity. Sooner or later we probably have to trade off portability, capacity, etc., in order to reach the theoretical 100W limit of USB-C Power Delivery

#21

A good quality 18650 gives about 12W from a 3400mah cell so an 8 cell 26800mah portable charger has a theoretical 100W safe upper limit. A recharge of about 5W is an upper limit, such as if you held the Mini+ it gets pretty hot recharging, but its all on its own shedding its heat in all directions, if you tried to work each 18650 recharging at that 5W/cel in a 8 cell 100Wh 26800mah package, you’d have 2/3rds of that heat going into the other cells and a real overheating problem. This is why the recharge speed per mah drops with a bigger mah. So say I wanted to carry 30Ah, I’d actually recharge faster with 3 10Ah all taking a 2A input for 6A aggregate ingest.

The issue is the heat from the cells and the heat from an imperfect DC-DC conversion is all magnified if you put a 100W output in a small package. There is less surface area the bigger the volume per cell. So the ability to scale wattage with size is a thermal challenge. This is just physical, maths and anyone’s opinion to contradictory is putting lives at risk.

I’d rather be safe than sorry. I thiink the current 30W limit can be improved with IQ2 which will waste less heat for a higher wattage so a slightly less thermal problem. If you also shape to be more slab like to increase the surface area per volume it will also shed heat a little better, so the Lithium Poly which can be shaped to be thinner than 18650 will improve. You see this for example in the slab shape difference of the Powercore II 10000 relative to the Powercore 10000.

I’d have thought a 60W output is viable by end of the year. I think 100W output (i.e. exhaust all of its energy in an hour) is going to be at risk of fire, and I’d hate to buy a $99 100W battery to find its banned on flights due to a few exploding.

Far more viable is to use own common sense, if you’re about to be sat on a long flight working, don’t sit there til near the end of the flight til its a flat laptop and then complain of a slow recharge, rather better use that time sat down and plug in your 30W or 60W charger and slow the drain (worse case) or slowly charge (more common) and just do not expect the recharge speed of a 100W wall charger. I think that is both highly practical and safer. You then get into the taxi with a charged laptop and not plug when moving a lot.

#22

You can’t forget their customer service, either!

#23

@nigelhealy I have seen batteries with over 60W output, Rav Power seems to be the first, plus they have an AC adapter on it as well. Anker could easily reverse engineer this battery and make it better.

#24

You mean the ones with fans because it get so hot.

Which is rated 85W, weighs 29.9oz which compared to the Anker Powerrcore 26800 which is 17.3oz, makes it 73% heavier. It costs $170.

You see my point, we’re thermally limited. You want that increase to 85W and add $$$ and an extra 12.5oz of weight? Are you sure you’d not rather just save money and weight and just plug in the battery earlier?

I do think Anker is being a bit too slow and cautious, but I also think about 60W is a 2017 maximum I would spend my own money on, particularly in a situation like flying.

YMMV.
