I have been looking at the upper range mAh Power Banks allowed by the TSA. Afaik the maximum allowed is 27000mAh. Quality, future proofing & pricing are my concerns. The two top brands I've identified for quality are Anker & RAVPower. I want to keep my pricing to $100 before taxes. I was also influenced by shorter charging times of phones etc. & recharging times of the Power Banks themselves. The Anker I'm looking at is: Anker PowerCore+ 19000mAh PD Hybrid Portable Charger and USB-C Hub with Included USB-C 30W PD Wall Charger $70 Anker A1362 Recharge Time 3.5 Hours Power Delivery: Deliver full-speed 27W charging to USB-C phones, tablets, laptops, etc. Hub Mode for Data Sync and Connecting Accessories And the RAVPower is two separate purchases because a 30W PD Wall Charger is not included: RAVPower 20000mAh 60W PD 3.0 USB C Power Bank $50 RAVPower RP-PB201 Recharge Time 3.0 Hours Power Delivery: Deliver full-speed 60W charging to USB-C phones, tablets, laptops, etc. & the RAVPower 61W PD USB C Charger[GaN Tech] Type C Wall Charger $25 RAVPower RP-PC112 (the 30W was only $3 cheaper) Alternate suggestions welcomed. I ended up with ~20000mAh solutions because 27000mAh quality solutions were over $100.
