Energizer Ultimate PowerSource Pro

Questions

I can't find anything which says the exact type of Li-ion battery this uses.

• BatteryBiz: manufacturer? Or does Duracell make it?
  • Duracell does not show this one on their power bank products page. Their closest equivalent is the Power 1000 (solar panels sold separately)
• Costco; got it here on 2023/08/15, on sale for $1000
• Amazon wants $1900 for it -- significantly more than Costco's non-sale price
