While perusing fasttech I came upon some new pens that have built in rechargeable batteries with a standard micro usb port for about $10. Ordered 2 of them on the 4th and they arrived on the 19th which is a normal travel time from China to the U.S.
Page where they can be found:
They are offered with either a green or red diode and a few different colored hosts.

$9.66 Z-07 5mW 532nm Single Dot Green Laser Pointer Pen - built-in 300mAh rechargeable Li-ion battery at FastTech - Worldwide Free Shipping
According to the Fasttech info. the battery is a 300mAh lithium and operates at a 50mA draw.
You can see a little hole behind the button which is allows you to see a red/blue light. There's no instructions but what I figured out is that as long as the battery has enough charge it will remain blue and when it turns red you need to recharge.
They initially had just enough charge to output about 35mW but need to be charged before use. I charged them for 5 hours and the LED was always red so as far as I can tell there's no indication of when they are fully charged. The units are very light but it's kind of nice having a green host and the little LED as if it were a more expensive unit than it is. Tempted to get the pink one just for something different.
After charging they output 61 and 70mW.
Shaky pic but itt's just to show the change in color to blue led.
Uses a typical plastic lens at the end of a holder for focusing which means time to make them fully focusable Yes they can light a green headed match with ease
Had also purchased a couple of the 5V 532nm modules and put them in a couple of hosts after adjusting the pots to .43A outputting 91 and 121mW. Both are fully focus-able of course.
All I did was use epoxy to glue the top section of the module that has the lens to the cap (after tightening down the middle section and scraping the top of the pen host inside so the cap would turn).
Went through all of my 532nm pens that I hadnt already made focusable and after some testing to see what power was needed to light a green tipped match I made everything 50mW and over fully focus-able in about 3 hours Sunday afternoon.
