    • This is a pretty nice battery pack
Color: black
If you want to avoid trying to find wall plugs at the airport or just trying to have an emergency battery pack then this is the one for you. First thing about this is that I actually had to get a replacement unit. The first unit the power button was actually sinking in and getting stuck so make sure you press the power button a few times when you first get it. It should just be a small press and not go all the way into the unit. This unit is a bit on the heavy side so be aware of that when packing I would say this thing weights close to five pounds more or little less. It is pretty compact so it can fit in most backpacks. It comes with its own carrying bag as well that will protect it from external scratches. The outer layer is a pretty anti slide surface in my opinion so you are not going to be sliding this off of the desk or anything. This battery pack is pretty strong. I tried to power a monitor with it and it actually did for several minutes before running out of power although I would not recommend using this battery for that purpose but it is definitely a good thing to note about it. It has two ways of charging your laptop. From what I can tell it can charge your laptop via type C port or a wall plug that is provided. Be aware that with the type c port charging for the battery you will require a strong power brick to charge the battery. That being said it can actually charge a macbook via type c to type c which is pretty nice if you are trying to charge two laptops at the same time although the charging is extremely diminished doing this. There is an actual number gauge to show how much power is left in the battery which is really nice. I am not needing to guess how much percentage is left before it dies. The charging time for this device can be close to six hours or more from dead to full, but it provides you laptop with up to eight hours of battery life. I was able to power a laptop with no battery for about four hours alone on just this device alone. Be aware that this device does get warm while it is in usage so be careful not to have this device say under a blanket or inside the carrying case when you are using it as the carrying case is made of insulated material. There are also several USB ports to plug in your phone if you need to. You can charge your phone about six to seven times over before needing to recharge your device again. It does come with a type c cable and the charging cable you can plug into the wall. In order to power this device on you will need to push and hold the button for about two to three seconds before it starts working in the wall outlet part of the battery. If you are just charging your phone, all you need to do is press the power button and it should start charging immediately from what I can tell. It does support fast charging for phones from what I can tell which is nice. I really like the battery for charging my macbook or windows laptop. It really has a strong charging capability able to charge your phone and laptop at the same time. It has a rather nice carrying case to protect the battery from external damage. Finally, it allows you to not have to worry about finding that wall plug to charge your laptop while you are traveling. ... show more

    • Doesn’t hold a charge
The device feels quality made and nice materials. It’s a bit heavier which makes sense from the stated storage capacity however dismal and disappointing the performance. If I plugged something in my phone or computer - it’d only charge it a little before it was out of power. Wayyy less than it claimed. Plus it took so long to charge the power bank - hours and then if you plugged something in it would die in 20 min. Maybe it was a dud but was not worth it and there’s better options out there. ... show more

    • Useful, but.... suboptimal design, heavy, inefficient, and noisy
Color: black
A generally good concept, except for some shortcomings. Everything has a cost, not just in price but in tradeoffs. For anyone with an already heavy computer bag, this additional weight and bulk are going to be noticed immediately. If you want power, you pay for it in several dimensions. There is no free joule. Experience shows that it takes about 4-5 hours to charge a depleted battery pack. That is about twice as long as it will power a typical Thinkpad using the AC outlet, though you can use the AC outlet power while the battery pack is being charged. In one test I completely removed the OEM battery from the Thinkpad and the battery pack successfully powered the computer for 2.5 hours on AC OUT without dropping below the recommended 20 percent minimum charge level. Note that the 20 percent is an industry recommendation but not mentioned by the distributor/manufacturer. For a typical laptop that calls for 19-20 volts DC, a far better design solution would have been a DC OUT at 19 VDC. Some Kristonia power products evidently have this feature. Instead, with this device, you have to use AC OUT to run through your laptop AC/DC converter/adapter, and that involves enormous inefficiencies. You lose energy in the DC=> AC conversion within the battery pack, then again with the AC=>DC conversion at your laptop adapter, and the battery pack then has to run a fan to cools its conversion innards, resulting in not just power losses but a bit of noise that may not be welcome to everyone. That fan appears to stay on when supply AC power out, rather than only operating when the internal components require cooling. Another design shortcoming. The "user manual" is the size of a post-card, with type too small to be read normally. To the device distributor: Redesign this thing for a 19 VDC OUT port, and a set of DC tip/connectors for a versatile range of laptops, and you will have a 5-star winner. Nice points: The power status display is a plus. The carrying case is a nice bit of foofoo. None of the components run hot. The AC/DC external adapter meets US safety standards (though the battery pack unit doesn't) The watt-hours output is clearly marked on the battery pack case to shore up your arguments with the unschooled knuckledraggers at TSA Speaking of TSA, the advertised 99.9 watt-hours would mean this is as powerful a "spare battery" pack as TSA and airlines would normally allow for carry-on. If you know how to press buttons, you should be able to operate in pass-through mode, charging the battery pack from an AC source while also supplying power to the AC and DC out ports. Summary: the product is a limited success, reflecting some unfortunate engineering tradeoffs resulting in inefficient power supply and limited utility of the device. ... show more

    • Solid power
Color: black
I used it to power my CPAP on a camping trip. If I adjusted the CPAP settings, I could get it to run for 6 hours. It solved a critical problem.

    • Did not work great.
Color: black
I got this for my Cpap dream station 2 but it didn’t work. Maybe the battery was defective because it wouldn’t even turn on after initial testing. Ended up going with another more expensive option and it works well.
