Our community has rated this post as helpful. If you agree, why not thank WoodSlayR

Sorry, but 50 cents per Wh is not a good price these days, especially for a newcomer (UDPOWER was founded in 2023) off-brand product. Another couple of important things to point out is, that to charge at the claimed hypercharge rating of 165 watts, you have to utilize the 65W USBC input along with 100W with the AC to DC adaptor at the same time for the claimed hypercharge rating of 165W, not to mention the AC-to-DC adaptor is a large old-school power-brick style adaptor. Lastly, the solar input, the 12v car input, and the AC adaptor input all use the same port so only one can be used at a time. You'll need to utilize the 65W USBC port and this port at the same time to achieve 165W of hypercharging. Terrible design IMO.

The C600 for $145 is a better deal.

Even better, the Oupes exodus 1500 for a little over double the cost but is 6 times the capacity, 4 times the output. 4 times the solar input and no adaptors or charging bricks needed.
