Phone accessories look simple until you stand in front of a wall of chargers, cables and cases with confusing labels like “PD 3.1,” “Qi2” and “9H.” This Alaikas.com guide translates those labels into plain buying advice, so you get gear that charges quickly, lasts longer and actually fits the way you use your phone.
At Alaikas.com, our editors focus on categories, standards and features rather than pushing one product, and you buy directly from the independent sellers and retailers you choose. This guide is part of our Tech Accessories hub, where you will also find advice on audio gear and desk setups.
What Phone Accessories Do Most People Actually Need?
Before buying anything, think about where your phone lets you down. Most everyday frustrations come from a handful of gaps:
- A fast, reliable wall charger that can also handle a tablet or laptop.
- One or two good cables in lengths that suit your bedside, car and desk.
- A wireless charger if you like to set your phone down rather than plug it in.
- A power bank for travel, commuting or long days away from an outlet.
- A protective case and screen protector to avoid expensive repairs.
You rarely need everything at once. Start with the accessory that solves your most common problem, then add the rest over time.
How to Choose a USB-C Charger at Alaikas.com
Almost every recent phone charges over USB-C, and the standard that matters most is USB Power Delivery (USB PD). With PD, the charger and phone negotiate the right voltage and current before power flows, which is why a single PD charger can safely charge an earbud case, a phone and a laptop. The USB Implementers Forum (USB-IF) maintains the USB specifications and runs the certification program.
Understanding wattage
- 20W to 30W covers fast charging for most phones.
- 45W to 65W is a sweet spot if you also want to charge a tablet or a lightweight laptop.
- 100W and above suits larger laptops or charging several devices from one multi-port charger.
The original USB PD standard tops out at 100W. The newer PD 3.1 Extended Power Range raises that ceiling to 240W for devices and cables that support it. Some Android phones also use the PPS (Programmable Power Supply) feature of USB PD for their fastest charging modes, so check whether your phone lists PPS before buying a charger for it.
Multi-port chargers
Multi-port chargers split their total wattage between ports. A “65W” charger might deliver the full 65W from one port but only 45W and 20W when two devices are plugged in. Read the port-by-port breakdown on the listing or packaging. Gallium nitride (GaN) chargers are popular because they pack more power into a smaller body, though the safety and certification marks still matter more than the material.
Which Cable Should You Buy?
A great charger is held back by a weak cable. USB-C cables vary in two main ways:
- Power rating. Standard USB-C cables carry up to 60W (3A). Cables rated for 100W or 240W contain an electronic marker chip that tells the charger they can safely handle 5A.
- Data speed. Many charging cables only support USB 2.0 speeds (480 Mbps), which is fine for charging but slow for transferring large video files. USB 3.x, USB4 and Thunderbolt cables move data much faster and often cost more.
Choose length based on where you charge. A 1-meter cable is tidy on a desk, while a 2-meter cable is handier at a bedside or on a couch. Braided jackets and reinforced strain relief at the connector tend to survive daily bending better.
How Does Wireless Charging Work, and What Is Qi2?
Wireless chargers use coils in the pad and the phone to transfer power. Qi is the long-standing standard from the Wireless Power Consortium, and Qi2 adds a Magnetic Power Profile so the phone snaps into the correct position. Better alignment means less wasted energy, less heat and more consistent charging speeds. The first Qi2 tier supports up to 15W, and the consortium has since introduced a higher 25W tier for compatible phones and chargers.
Keep these trade-offs in mind:
- Wireless charging is usually slower and warmer than a good wired charger.
- Thick cases, wallets or metal plates between phone and charger can block or slow charging.
- If your phone lacks built-in magnets, a “magnetic” or Qi2-ready case can add them.
- Stands keep the screen visible for notifications, while flat pads are better for bedside tables.
What to Know About Power Banks and Air Travel
Power bank capacity is listed in milliamp-hours (mAh), but airlines and safety rules use watt-hours (Wh). To convert, multiply mAh by the cell voltage (usually 3.6V or 3.7V) and divide by 1,000. A 10,000 mAh bank is about 37Wh, and a 20,000 mAh bank is about 74Wh.
Real-world output is lower than the label because some energy is lost during conversion, so a 10,000 mAh bank will not deliver a full 10,000 mAh to your phone.
Flying with a power bank
Under the FAA’s PackSafe guidance on lithium batteries:
- Spare lithium batteries and power banks must go in your carry-on bag, never in checked luggage.
- Batteries up to 100Wh are allowed without airline approval.
- Batteries over 100Wh and up to 160Wh need airline approval, and you are generally limited to two spares.
- Batteries over 160Wh are not allowed in passenger baggage.
Some airlines add their own rules, such as limiting the use of power banks during the flight, so check with your carrier before you travel. A power bank with USB PD output and pass-through charging is a convenient travel companion because it can top up your phone and laptop from one wall outlet.
Cases and Screen Protectors: How Much Protection Do You Need?
A case is the cheapest insurance for your phone. Match the case to your habits:
- Slim cases add grip and scratch protection with little bulk.
- Rugged cases use thicker corners and raised edges for frequent drops or outdoor work.
- Wallet and folio cases keep cards close but can interfere with wireless charging.
- Magnetic cases add Qi2 or MagSafe-style magnets for mounts and wireless chargers.
Look for raised lips around the screen and camera, and buttons that still feel clicky. Some cases cite drop testing, but test methods vary by brand, so treat these claims as rough guidance.
For screen protectors, tempered glass is the most common choice. A “9H” label refers to a pencil hardness test, not a guarantee that the glass cannot crack. Choose one with an installation frame, and confirm it plays well with your case so the edges do not lift.
Phone Accessory Checklist: What to Look For

| Wall charger | USB PD wattage, PPS support | Per-port wattage listed clearly, safety certification marks | Vague “fast charge” claims with no wattage |
| USB-C cable | Power rating (60W, 100W or 240W) and data speed | USB-IF certification, reinforced connectors | Unlabeled cables for laptop charging |
| Wireless charger | Qi or Qi2, wattage | Qi2 certification, magnetic alignment | No certification, poor heat management |
| Power bank | Capacity in mAh and Wh, output wattage | Wh printed on the label, USB PD output | Capacity claims that seem too good for the size |
| Case | Fit, material, magnet support | Raised edges, cutouts that match your model | Cases that block wireless charging if you rely on it |
| Screen protector | Coverage and case compatibility | Alignment tray, edge-to-edge fit | Protectors that lift when the case is on |
How Alaikas.com Readers Can Shop Safely for Tech
Because Alaikas.com does not run its own checkout, you complete every purchase with an independent seller or retailer. That makes it worth taking a minute to check who you are buying from. Our guide on how buying from Alaikas.com works explains the process, and our safe online shopping checklist covers seller checks, secure payment and spotting deals that are too good to be true.
For chargers and batteries in particular, be wary of listings without clear specifications, safety marks or a real seller address. Cheap, uncertified power accessories are the category most likely to cause problems.

Phone Accessories: Frequently Asked Questions
Does Alaikas.com sell phone chargers and cases?
No. Alaikas.com does not sell, stock or ship products. Our editors explain the features and standards that matter, such as USB-C Power Delivery and Qi2, and point you toward categories and the kinds of retailers that carry them. You buy directly from independent sellers and retailers, so their prices, shipping and return policies are the ones that apply to your order.
Will a higher-wattage charger damage my phone?
No, not if it follows the USB Power Delivery standard. The phone and charger negotiate a safe voltage and current before charging starts, so a phone that accepts 25W will only draw about 25W from a 65W charger. The extra headroom simply lets the same charger power a tablet or laptop. The real risks come from uncertified, very cheap chargers that cut corners on safety components.
How do I work out the watt-hour rating of a power bank?
Multiply the capacity in milliamp-hours by the cell voltage, then divide by 1,000. Most power banks use cells rated around 3.6 or 3.7 volts, so a 20,000 mAh bank is roughly 72 to 74 watt-hours. Many power banks print the Wh figure on the label, which is the number airport screeners and airline staff look for when checking battery limits.
Is Qi2 the same as MagSafe?
Not exactly. Qi2 is an open standard from the Wireless Power Consortium, and its Magnetic Power Profile was based on the magnetic alignment design Apple contributed from MagSafe. In practice, Qi2 chargers and Qi2-ready phones snap together magnetically in a similar way. Older Qi pads without magnets still work with most phones, but alignment and speed can be less consistent.
Are tempered glass screen protectors worth it?
For most people, yes. Tempered glass protectors are inexpensive and absorb scratches and some impact that would otherwise reach the screen itself, which is far more costly to replace. Look for a good fit around the edges, an alignment tray for easy installation and compatibility with your case. Treat a 9H label as a pencil hardness test result, not a promise that the glass is unbreakable.
