You have to apply the promo twice for it to work, but it does work.

"No soul bro, too bookoo." What was that, Full Metal Jacket?
Nice price for a unit with a decent sized battery.

you must be doing it wrong, trying to jump a battery that's too dead or buying the absolute junk brand. ive been jumping cars with various brands over 10yrs now. Stick with gooloo or noco and shouldn't have any issue.

Bookoo? Have you used one of these? Is this something I'll have to charge before I go anywhere or can I just set it in the back and forget it?

Worked surprisingly well for me! Smaller 90's Acura battery but it was well below 6v when I checked with my multimeter, connected this, got back into the driver seat, started right away. I thought for sure my battery was too dead but it worked! Still showed full battery on the little blue lights. Ordered a solar charger now too, I want to see how long my old battery lasts since it's already 5+yrs old, keeping the Bookoo in the trunk.
Best practice is to either use or recharge every few months, try not to fully charge or fully drain unless necessary or going on a trip. Only complaint is the output charge is fairly slow as a backup for my phone or other items, also it's a slippery plastic which made it kinda tricky when hooking up under the hood.

Ordered one for a late father's day gift. I have one and it's saved me multiple times with my Subaru Ascent. This is a really good price for 20000mAh 4500A. Thanks OP!
