Just bought a second one of these.
Like UPS batteries, starting draws a ton of current all at once. The
intended use will limit the life of the battery.
I have a Bolt Power D28, which has two USB charging ports, and an outlet
that can be different voltages from 12v to 19v -- it'd run a laptop
nicely for quite a while. The supplied "laptop" cable would power a KX3
nicely.
The Bolt D29 has more capacity, but doesn't have the "laptop" power.
I paid about $60 each on Amazon (on sale).
The D29 is 18 ah, the D28 is 13.6 ah.
We've actually used the smaller one to start a car.

I'm seeing a lot of good deals on these Lithium battery, emergency "car
starter" packs.
They're typically rates from 12000 to 24000 mA-hr, or, as we're inclined to
call them 18 to 24 Amp-Hr.
Prices vary from about $40 up over $80.
They come in a nice durable case with a charger and output cables.
At first glance, they'd seem ideal for a field pack for portable radio
operation.
They certainly can't be limited in their current capability, considering
what it takes to start even a small car's engine.
But then, their ratings may be extremely optimistic.
Anybody gat any thoughts on these?
