Mobile Battery to Charge/Power R5m2

[StevenAunan]

Having moved from the R6 to the R5m2, I'm looking for a new external power option that I can strap to a tripod. I'd like a power pack with at least 30000mAh and 45W (preferably more, but I also don't need 130W). This post collects the information I've gathered in support of my quest. If you're already using a power bank with the R5m2, please let me know! Thanks.

Canon's documentation says "output of at least 45 W is recommended" for the R5m2. I can't use the recommended "USB Power Adapter PD-E1 or PD-E2" because they require AC. Besides that, the PD-E2 is $150, B&H says the PD-E1 will charge but not power, and as noted below I already have an AC to USB power block. The DR-E6P power coupler is $89 and redundant.

What I have that does not work:

• Watson AC-E6 power adapter with "dummy battery" DC coupler DR-E6 delivers 8V and 3A (24W, does not power the camera)
• IXNine 26800mAh USB-C power pack delivers 3.7V and 3A (will charge but not power)

This works like the PD-E2, but was less than $20 (newer version is $25)

• Novoo RG68 67W USB-C AC charger delivers between 5V/3A to 20V/3.35A (will charge and power)

Canon says the Anker 537 PowerCore 65W (model A1379) has been verified, but capacity is only 24,000mAh.

Amazon has a few no-name 50,000 mAh batteries that deliver up to 130W and cost about $50. But will they work with the R5m2? Canon's documentation warns that some third-party devices will not.
