Battery Backup For Laptop When Power Outage?

Hey thanks for that info. Amazon is very good with returns but the thing that made me not want to get it is because its through a 3rd party and fulfilled by amazon. Thus the seller has 92 percent feedback which to me isn't that good on amazon. You agree on this?


Also when i first get it, i have to charge it up first right? Also could i use it the way i mentioned earlier? Example use my laptop as is charged and when there is power outage, use it on battery for about an hour, then when battery is close to be out, plug this in?


Also if you are doing something intensive, probably 1 hour on it? Is there a chance that it wouldn't even charge 100%? I still am amazed you get this many hours on it.


Also what laptop model do you have by the way? I looked through the thread and didnt see you mention what model you have. Because i only get between 1 to 1 hour 15 minute battery on my laptop when unplugged.

Hey man thanks. I just got the powerbank now and got it from dell as oppose to amazon.


One other thing i want to ask.


Do you know how much Volts it has? Because im planning on traveling with it internationally. I checked online and there is a formula to find the total Wh. But it seem i need to know the volts of this? Do you know how much Wh this power bank has? I have it at the moment and dont want to open it yet.

Hey Try, i opened the package. There is a powerbank and like 2 of these cables are like almost the same? One is bigger, the other is smaller? Its where you stick it to charge the laptop. One fits... the smaller on... the other is way too big. Do you know why i got 2 of them? I assume one is for certain dell laptops and the other is for other laptops and see which fits which?


Also i got a paper that says important info and to flash the bios. Is this needed to be done? It say its recommended to flash the bios before the latest version. Did you do that? I dont want to try anything now in case i mess something up.

There is also this cyclinder thing that came along with it as well.

Im looking at the quick start guide.


So basically to charge this power bank, i have to use the charger that came along with my dell xps 15 9550 right? However, this is what does not make sense.


Right now i have the dell xps charger connect to my laptop charging. Now i unplug the part that comes into my lap


In the picture, it shows the power adapter not included... this is the power adapter i have for my dell xps 15 9550. It shows its plugged into an outlet. So take that end that connects to my laptop to charge it and plug it in the first spot of the power bank to first charge the power bank right? But how long do i do that for? What is confusing it why does it seem like there are 2 places where you could plug it in? Example it fits in the first hole and not 2nd hole on the powerbank. I assume thats because certain laptops use either a small one or a big one? The picture shows it being plugged in to the 2nd hole.

Whats then confusing is after you do a full charge of the power bank... which should take how long? Then you connect it to the dell xps laptop right? So stick the end where you have to open the thing and connect it to that spot on the powerbank? Then on the opposite end, connect it to the spot where you normally connect your charger to charge your laptop? What confuses me here is why are there 2 of these power out cables? Also the cyclinder thing i read is called a ferrite core. Is it necessary to attach that as shown in the diagram?

Hi there. Back of the power bank shows 11.1 V = 65 wH so that means its under 100 wH and good for it.


Okay that make sense now with why there are 2 cables.


Okay just say the cyclinder thing.


Would you say its necessary to do the bios thing as mentioned in those directions? I always was worried of doing something like that because if its a question in it where im not sure what to do, then i don't want to mess this part up.


Im charging the powerbank right now.
