Nitecore Carbon 6k Power Bank vs Polar Grit X: which should you buy?
If saving weight is your priority, the Polar Grit X wins — at 64 g it is 24 g (27%) lighter than the Nitecore Carbon 6k Power Bank (88 g). That said, the heavier option may justify the extra grams with more capacity, durability or comfort, so weigh the trade-off against how you'll use it.
