Buy the Anker A1383 Power Bank.

It carries four times the real charge, powers more than just your phone, and comes from a brand that does not fail on you at the worst moment.

What was compared

1. More real charge, not just a bigger number
Anker's 20,000mAh gives you roughly four full iPhone charges. TRKOY's 5,000mAh loses close to 40% to heat over MagSafe, leaving barely enough for one partial top-up before you are hunting for an outlet again.
2. Charges your laptop, not just your phone
Anker pushes up to 87W over USB-C, enough to genuinely top up a MacBook, a Switch or a Samsung phone fast. TRKOY caps out near 10-20W wireless and only ever works on phones.
3. No cable to dig for, or forget at home
Anker's USB-C cable is built in, so it is there the moment you need it. TRKOY needs you to carry your own cable for wired use, or trust magnets that can slip loose in a bag.
4. A name that survives daily abuse, not just a spec sheet
Anker holds 4.6 stars across 8,800+ reviews and a track record of packs that do not swell or die early. TRKOY sits at 4.1 stars, sold through a smaller, lesser-known storefront.
5. Yes, TRKOY is thinner. That is all it wins.
TRKOY's card-slim magnetic design is real, and if you only want a light iPhone top-up on a short walk, that is genuinely useful, go for it. But most people carrying a charger for a full day or a trip need the capacity and power Anker has and TRKOY simply does not.
