Ten numbers on the box, and what each one actually promises
Ten pages, one per figure printed on a box. Each one says what the number does promise, what it does not, and where it misleads people at the counter.
- The wattage on the box is a budget, not a promise99W — The unit can move up to that many watts in total, counting everything plugged into it at the same time.
- mAh counts charge, watt-hours count energy10,000 mAh — The cells inside store that much charge at their own internal voltage.
- Magnets that stick are not the same as MagSafeMagSafe compatible — The listing states the accessory has magnets arranged to hold onto a phone or a case that also has magnets.
- Noise canceling, transparency, and what neither one isANC — Microphones and processing will reduce some outside sound, and can also deliberately let it back in.
- Power Delivery is a negotiation, not a speedPD 3.0 · PPS — The charger can hold a structured conversation with a device about voltage and current.
- The connector changed and the cable drawer did notUSB-C — A physical connector that fits the port, in one orientation or the other.
- The cable decides more of this than the charger does240W — The cable is built and marked to carry up to that much power without being the weak link.
- An IPX number is a lab test, not a swimming licenseIPX5 — The product passed a specific, defined water test at the stated level.
- Playtime hours usually count the case60H — A total listening figure measured by the manufacturer under conditions they chose.
- GaN is about size and heat, not extra speedGaN — A more efficient switching material, which allows a smaller body and less waste heat for the same output.

What this site does not do
- No prices and no ratings.
- No testing claims and no invented experts.
- No promise that a number on a box will reach your phone.
Almost every number on an accessory box is technically true and answers a question nobody asked. This site translates them into the one that matters: does it fit the phone you own.

What that comes to
iPhone 15, 16 and 17 uses USB-C and charges over USB Power Delivery over USB-C. Magnetic accessories: built-in magnet ring, no case required. So you want a wall charger, with a cable that has the right ends for USB-C.
Share per device = stated total ÷ devices charging
Take a unit stating 45W total: 45 ÷ 1 = 45W as an even share across one device. Most manufacturers do not publish how they actually divide it, so an even split is an illustration rather than a specification.

Real charging speed depends on the phone, the cable, the protocol both ends support, and the battery temperature at the time. Nothing here predicts how fast a particular phone will charge from a particular charger, and no wattage on a box does either.

What fits which phone
Find the phone you actually own| Phone family | Connector | Magnetic grip | Fast charge protocol | Where it gets tricky |
|---|---|---|---|---|
| iPhone 15, 16 and 17 | USB-C | Built-in magnet ring, no case required | USB Power Delivery over USB-C | Lightning cables from an older iPhone no longer fit anything on this phone |
| iPhone 14 and older | Lightning | Magnet ring built into iPhone 12 through 14; none on iPhone 11 and older | USB Power Delivery, but only over a USB-C to Lightning cable | The old USB-A to Lightning cable charges slowly and never says so |
| Samsung Galaxy S | USB-C | Case only — no magnet ring built into the phone | USB Power Delivery with PPS; Samsung publishes its own charging figures | Magnetic accessories need a magnetic case, which many buyers discover after the grip arrives |
| Google Pixel | USB-C | Case only on most models — check the specific model before buying magnets | USB Power Delivery, with PPS on models where Google states it | Charging wattage claims vary by model, so the family name is not enough to shop by |
| Budget Android phones | USB-C on most current models, with micro-USB still appearing at the low end | Case only, and a magnetic case may not exist for the specific model | Varies widely — often a manufacturer protocol with a slow standard fallback | The specific model decides everything here, and generic advice is worth less than usual |
| iPads and tablets | USB-C on current models, with Lightning on some older iPads | Magnets are for covers and stands, not for a charging ring | USB Power Delivery | A charger that is generous for a phone can be visibly slow for a tablet |
Loadouts for a situation, not for a person
Loadouts built for a situation5 items · 3 to leave out
The commuter daily carry
You are out of the house for ten or twelve hours, on public transport for some of it, and nowhere near a reliable outlet in between. Nothing here is about emergencies. It is about not spending the afternoon watching a battery percentage.

The long-haul flight kit
Twelve hours in a seat, an outlet that may or may not exist and may or may not work, and a bag that goes through a security scanner at both ends. This kit is chosen around two constraints: what the arithmetic allows and what fits in a seat pocket.
Open the list5 items · 3 to leave out
Two phones, one car, six hours
A driver, a passenger, a navigation app running the whole way, and one 12V socket. This is the situation where the difference between a total wattage and a per-port wattage stops being a technicality.
Open the list5 items · 3 to leave out
The dorm room and lecture hall kit
One room, two outlets in the wrong places, a phone, a laptop, earbuds, and a lecture hall where the nearest socket is four seats away. This is the one kit where a shared wattage budget is the right answer rather than a compromise.

Filming without holding anything
You are recording yourself doing something with both hands: cooking, repairing, demonstrating. The phone has to stay put, stay powered, and stay recoverable when it does not stay put.

Capacity on the bank
How many banks are you carrying
The arithmetic, printed
Wh = mAh ÷ 1000 × 3.7
10,000 ÷ 1000 × 3.7 = 37 Wh per bank.
1 bank × 37 Wh = 37 Wh carried in total.
Each bank is well below the commonly published 100 Wh figure.
Before you pack it
- Lithium power banks go in carry-on baggage. Never in checked baggage.
- The 100 Wh figure and the rules around it are published by the FAA and by each airline. This tool does the arithmetic and nothing else.
- “Flight-safe” and “TSA approved” in a product listing are seller claims. Neither the TSA nor the FAA approves individual power bank models.
- Check with your own carrier before you travel. This site does not tell you that any particular bank will be permitted, because that is not a decision it can make.
- Do not pack or charge a bank that is swollen, punctured, wet, or hot to the touch.
Six answers, given plainly
Does a 99W car charger give my phone 99W?
No. That is the total across all ports at once, and the split is usually not published. One phone gets whatever the unit allocates it, and the listing does not say what that is.
Is 10,000 mAh two full phone charges?
Rarely. That is roughly 37 Wh of stored energy, and converting it up to what a phone accepts costs some of it as heat. Stored is not delivered.
Does "MagSafe compatible" mean Apple approved it?
No. On a third-party listing it is a seller statement about magnet alignment. It is not a certification, and it says nothing about charging speed.
Can I swim with IPX5 earbuds?
No. Level 5 is a water jet test. Immersion is a different test at a different level, and none of these tests cover salt or chlorinated water.
Why did my new fast charger change nothing?
Usually the cable, sometimes the protocol. A cable without the right rating caps the whole chain, and a charger that names only a wattage may fall back to something slow.
Do 60 hours of playtime mean 60 hours of listening?
No. That figure counts the buds plus every recharge the case can give them. The buds themselves run for a fraction of it before going back in.

A power bank is sold in one unit and regulated in another.
Milliamp-hours measure charge; watt-hours measure energy. Airlines use watt-hours because milliamp-hours are meaningless without a voltage. Divide the mAh figure by 1000, multiply by 3.7, and you have the number that actually matters. Then remember that stored energy is not delivered energy: stepping the cell voltage up to what a phone accepts costs some of it, and wireless transfer costs more again.
The cable decides more of this than the charger does.
A chip inside a USB-C connector tells the charger what the cable can carry. Without one, the whole chain drops to a conservative level regardless of how capable either end is. This is the most common invisible bottleneck in a charging setup, and the least likely to be blamed. Buy the cable for the largest thing you own and the mystery goes away.
Magnets that stick are not the same as MagSafe.
On a third-party listing, "MagSafe compatible" describes an arrangement of magnets that will hold onto a phone or a case. That is the whole claim. It is not certification, it is not a charging speed, and on most non-Apple phones it depends entirely on the case rather than the phone. Alignment and speed are separate questions that share a marketing word.
All ten, in one place
- The wattage on the box is a budget, not a promise
- mAh counts charge, watt-hours count energy
- Magnets that stick are not the same as MagSafe
- Noise canceling, transparency, and what neither one is
- Power Delivery is a negotiation, not a speed
- The connector changed and the cable drawer did not
- The cable decides more of this than the charger does
- An IPX number is a lab test, not a swimming license
- Playtime hours usually count the case
- GaN is about size and heat, not extra speed
Method
How this site is written
- Every specification on this site is quoted from the product listing it came from, and written as "the listing states" so you always know whose claim it is.
- We publish no prices and no ratings. Prices change hourly and a star average is not a specification.
- We have not tested any of this. There are no testing claims anywhere on the site, and no invented experts with names and quotes.
- Where a figure is missing from a listing — a per-port split, a cable rating, a runtime — we say it is missing rather than estimating it.
- Safety material points at the organizations that publish the rules: the FAA, the CPSC, NHTSA, the FDA and the WHO. We do not restate their numbers in our own words.
- Links to Amazon are affiliate links. They pay for the site and change nothing about what is written on it.
