Pros & Cons
INIU Carry P50-E1
Pros
- +45W is enough to charge a phone at full speed and top up a small laptop
- +The lanyard cable means you can leave a separate cable at home
- +Only 160g
- +Digital percentage rather than four LED dots
Cons
- −No confirmed standalone Amazon listing could be matched to this exact model number — INIU runs several near-identical 45W 10,000mAh SKUs, so verify the model before buying
- −Output drops to 15W shared when several devices are attached
- −Pass-through charging is not documented by INIU
Nitecore NB10000 Gen4
Pros
- +143g is a genuine differentiator if you are counting grams for hiking or ultralight travel
- +Carbon fibre shell is tougher than any plastic rival here
- +Nitecore publishes the watt-hour figure, so you can prove airline compliance at a gate
- +True pass-through — it charges itself and a device at the same time
Cons
- −22.5W is the slowest output of any modern bank here, and only 15W once both ports are used
- −$69.95 for 10,000mAh is expensive — you are paying for the weight saving
- −No percentage display, just a check indicator
