About this deal:
My research indicates that this Black and Decker GoPak 12V 1.5 Ah Lithium-Ion Battery and USB Charger is $8.14 lower (50% savings) than the next best available price from a reputable merchant with prices starting at $16.13 at the time of this posting.
Curious enough on these to find their peak discharge amp's on the 12v side, might be a usefull thing if nothing else, $20 to play with them till they do blue smoke what could go wrong
I really think-no matter your opinion on BD-the normal batteries in their products that are lithium hold up well. If you research knock offs their reviews are usually not good with very limited life span.
12V (nominally 10.8V) 1.5Ah battery pack = (3) 1.5Ah 18650 cells = equivalent to a 4500mAh power bank, assuming other things like efficiency being equal. Assuming 90% efficiency, a 4500mAh (at 3.6V) power bank can output around (3.6V * 4500mAh / 5.0V * 90%) = 2916mAh at USB 5V.
Compared to power banks, power tool batteries have thicker enclosures, larger circuit boards with room for heat dissipation for the protection transistors. The electrical connection tabs add substantially to the thickness too. Power banks that still use 18650 cells have 3.0Ah+ cells, versus the puny 1.5Ah in the GoPak, and most power banks nowadays use LiPo flat-pack cells that are even more power dense and space efficient. You can probably get a 15000+mAh power bank for the size of the GoPak (4" width and 1.25" height per B&D, which is humongous for the meager capacity, my old school 13400mAh 3x18650 power bank is 4 x 3 x 7/8")
This GoPak is quite unique among power tool battery packs in that it is designed with pocketability in mind, with recessed electrical terminals and a smooth body.
This made me seriously wonder how power cores are doing the math. Turns out they actually measure the mah based on the batteries which are 3.7V. They just multiply the mah per battery times the number of batteries. So this should have four 1500 mah batteries in it for a total of 6000 mah.
You would have to tear it down to know for sure possibly. Less powerful than I had hopped.
SD has had some great PB deals like that $8 Novoo cube which turned out to be great compact charger, or the Mophie deal.
This isn't one of the better ones, at least depending on what's under the hood (cell quality) and how rugged the case is (that could potentially be a plus). Capacity wise, nope.

Is there any chance this pack could potentially have an even lower than standard 5v charge capacity due to the configuration of the cells? The cells are primarily configured for 12 volts. I wonder if they are stepping down the 12 volts to 5. If so, that's a Big Step Down.
I only paid attention to this because I'm working on a compact solar charger and noticed how large a loss you got every time you made a large voltage change.

Looks like it was meant to go with this "set" of ENTRY level tools:

if you are buying just for battery backup, you have much better options, this not a good deal at all.
3.6ah @ 5v is 36000 mah
Wait I'm wrong, yeah it's 3600. Shit.

Actually phone battery is measured at 3.7v not 5v, so it's more like 4800mAh
at this price I dont think 3600mah is worth it,
