Size is not impressive. You can get 20,000 mAh packs for $35. The higher voltage and wattage output is nice though. Should of put a bigger battery in it though.
 
As much as I like Razer mice and keyboards, most of their other peripherals are *stupidly* overpriced. I have an Aukey (a respected power bank brand) power bank with 30000 mAh, QC 3.0 and two USB Type A ports which costs $50. It also has an inbuilt torchlight xD I'll just slap one of the Razer stickers that came with my BlackWidow on it 😀
 
not bad for the size but it's WAAAAY overpriced...

basically you're paying for the looks and the name...

I bought 26800mAh/99.16Wh battery for $37.50...it's only 5V/5.5A total output with 2.4A output on one port...no USB-C...but extra outside battery can't be that expensive to produce or design...
 
My Anker is 20,000mah, has usb-c and two other ports, supports supports all quick charge standards, is somehow smaller than this thing, and it's $60 on Amazon including two cables. F this pos
 
you all don't get it: this ist one of the first usb-pd compatible power banks, if everything has been done right by razor it should be able to drive Laptops, Monitors and lots of other equipment and vice-versa be charged by every usb-pd capable device. The universal standard for Power Delivery makes this great and future proof, price is ok for early adopters.
 


It's complicated. But when you increase voltages you're going to lose capacity, either by energy loss during the transformation process (up scaling, 3.7V to 9V) or by running cells in series.
 


And if Anker were to configure those lithium cells in series to increase the cell output voltage from 3.7V to 7.4V to have a better conversion rate for the USB output at higher voltages the Amp-hours would drop in half, yet the Watt-hours would remain the same.
 
For $120 on amazon.com, you get a power bank that has a capacity of 50,000 mAh (185 watt hours) , along with an output up to 20V at 3 amps.
Overall, 12800 mAh is very little capacity, and a massive ripoff.

Keep in mind that many of these companies advertise charges based on the capacity without taking into account losses. For example, the DC to DC regulator in most power banks, will cause you to lose around 5-10% of the capacity to heat within that circuit, then the DC to DC conversion within the phone will often take an additional 10+%, same as with laptops, as these circuits are not designed for max efficiency,instead they are built t charge fast,and cost less. This also doesn't include the additional standby power used by most mobile devices when supplied with external power. Many devices use that time for background optimization, updating, and other forms of maintenance.

If you are buying a power bank, buy at least 20-50% more power than you think you will need.
