Which one charges an iPhone faster?

Both top out at 15W wireless. The 10K adds 27W USB-C wired output, which is faster than wireless on either.

How many phone charges do I get?

The 10K is rated for about 1.8 charges of an iPhone 15 Pro. The Nano's capacity is not stated, so treat it as a partial top-up.

Is the 10K worth the extra weight?

At 250 g it is a bag bank, not a pocket one. If you want a full day of charges plus a display and stand, the weight buys you that.

Does either work with Android?

Qi2 wireless works with Qi-compatible Android phones, but the magnetic alignment and 15W speed are tuned for MagSafe iPhones.

The Nano is $89.99 at Newegg.com as of November 7, 2026. The 10K's price was not given, so check it before deciding.
