I like the silver color of this portable battery. It comes with 80% charged. So I put it to the test. Once I plug in my laptop I can used 3.5 hours, and it also fully charged my lap top, which I can used for another 2.5 hours , and yet it still have another 20% on the battery for you to used. So I fully charged the battery, and used on my laptop again. The total I get from it is 8 hours which are very impress and it lasted the whole day of work for me while I am on the road. So that I do not have to worry about running out of power and have to run around to find somewhere I can plug in. This is a life saver for me. I like it that, it comes with two cable one for your charging device such as phone, tablet and another is for you to charge your battery. Best thing is it comes with AC adapter as well. It has a nice and very sturdy carrying case. Love the light feature where it shows you how many percent it your battery at. Also there is a green like when to indicate for you that it is ready for you to plug in your laptop. You can also turn that off when you are not plug in your computer. Oh not to forget it also can be use as a flash light. I also love that it has a build in fan so when it is in used it is not hot when you touch it as all. The fan is very quiet though - All and all if you are looking to free yourself from worry when is your laptop going black, or where can you plug in your laptop on the go. Get this - this will free you from all that and it is also give you the peace of mind when you on the go.

Never could get item to charge and was never able to use it.

Had this thing for almost 5 years now and it’s still going strong. Originally got it because it can charge a laptop and it has charged any laptop that I’ve hooked up to it. Other than that it charges other small devices. It doesn’t last that long, I would say it’s good for 4-5 phone charges. Pro tip: Use the usb-c to charge the power bank. It’s an input as well as output port and charges much faster than the micro usb.If you push the power button 1 time it will charge at lower wattage. Which will not activate the cooling fan. If you hold power down it activates the ac power as well as the cooling fan.It’s a big unit to carry around but overall I’m happy with this this unit. Doesn’t seem to have lost a lot of battery capacity either and all the lights on the face still work after 5 yrs.

I was concerned that the Medistrom battery recommended for powering the AirSense 10 CPAP machine would not last all night and the cost was $330. From reading reviews, it appeared that if the CPAP heated humidifier was using too much battery life and it would only last several hours.During reading the reviews, one user recommended the Sikon Laptop Charger External Battery pack, for CPAP use, which can be found on Amazon at: https://www.amazon.com/gp/product/B07S7TK88B/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1This battery is sold primarily for powering laptop computers. Thus, I purchased the Sikon External Battery pack to use with a medical CPAP device in preparation for a safari to Africa where I would not always have electricity overnight.I have been testing it out at home, with my Resmed Airsense 10 CPAP and this is what I found.1. I got 5 hrs use from it with the heated humidifier turned to a 5 setting.2. The second time I tried it, I turned the humidifier off and got 8 hrs use. Although the air was drier, I did not find that it prevented me from a comfortable sleep.The Sikon battery is a 110Wh/31200mAh lithium-ion battery. TSA says: “Lithium ion batteries with more than 100 watt hours (Wh) may be allowed in carry-on bags with airline approval.” "Delta Airlines says the following: "Customers are permitted to travel with lithium ion batteries tht contain a maximum of 160 watt-hours per battery. Lithium ion batteries not installed in a device must be in carry-on baggage and no more than two spares between 100 and 160 watt-hours are allowed." Check specific airlines for their policies.Pros:1. No special cable is needed to plug the CPAP into the Sikon battery. There is a standard two prong plug on the end of the battery so that the CPAP plug plugs directly into the battery.2. This battery has enough power to power a CPAP 5-8 hrs depending on use of the heated humidifier.3. A charging cable is provided using a USB-C port on the device.4. It comes with a lightweight carrying case but I think it would fit into the CPAP carrying case by itself.5. It has an emergency built in flashlight.6. It also comes with a micro-USB charging port and cable.7. Has a one USB output port, and one USB-C output port for charging.8. Cost was only $119 compared to $330 for the Medistrom battery.Cons:1. It weighs 2.4 lbs.2. It has a fan in the back end of the device that make a kind of “white noise” when running. I did not find this objectionable and it did not prevent me from falling or staying asleep. Those who use “white noise” to sleep might find this also works for that purpose.3. If the battery is fully depleted, I found it took about 10 hrs to fully charge the battery, using the provided USB-C adapter.

Excellent product and provides power to devices during storms.

Bought two of these 3 years ago with pretty minimal use. Travel was into and then a few feet out of my car maybe 12 or so times in 3 years and one of them no longer works. I can power it on but the fan wont start and the light flashes at me. I can still use the usb charging so atleast its not entirely useless. Just useless for what i use it for

I thought it wasn't working properly when I plugged it into my laptop. But you have to hold the power button on for a few seconds, and then it lights up and works perfectly. It does the job for me.As my laptop only lasts for a couple hours, so i'm able to continue working with this external power source. It was a bit expensive and it's heavy, but worth the money.It does the job. I look forward to camping season. Having it so that I can watch movies through the night on my tablet.
