The phone accessories most people actually need are a USB-C Power Delivery charger, one or two properly rated cables, a protective case with a screen protector, and a power bank if you travel. A Qi2 wireless charger is a nice extra if you like to set your phone down instead of plugging it in. This Alaikas.com guide explains what the labels on each one mean, so you can buy once and skip the duds.
We cover standards and features rather than pushing one brand, and you buy from the independent sellers and retailers you choose.
Key Takeaways
- A USB-C Power Delivery (PD) charger with enough wattage for your largest device is the most useful single phone accessory.
- Check a cable’s power rating (60W, 100W or 240W) and data speed before you rely on it for a laptop.
- Qi2 wireless chargers use magnets to line up the coils, which makes charging more consistent than older flat pads.
- Power banks go in your carry-on, and FAA rules allow batteries up to 100Wh without airline approval.
Which Phone Accessories Do You Really Need?
Start with where your phone lets you down. Most everyday frustrations come from a short list of gaps, and you rarely need to fix them all at once.
- A fast, reliable wall charger that can also top up a tablet or laptop.
- Good cables in lengths that suit your bedside, car and desk.
- A wireless charger if you prefer to set your phone down.
- A power bank for commuting, travel or long days away from an outlet.
- A case and screen protector to avoid expensive repairs.

How to Choose a USB-C Charger
Almost every recent phone charges over USB-C, and the standard that matters most is USB Power Delivery. With PD, the charger and the device agree on a safe voltage and current before power flows. That is why one PD charger can safely charge earbuds, a phone and a laptop. The USB Implementers Forum maintains the standard and explains it on its USB Power Delivery overview.
Understanding wattage
- 20W to 30W covers fast charging for most phones.
- 45W to 65W is a sweet spot if you also charge a tablet or a light laptop.
- 100W and up suits larger laptops or several devices on one multi-port charger.
Standard PD tops out at 100W, while PD 3.1 Extended Power Range raises the ceiling to 240W for supporting devices and cables. Many Android phones use the PPS (Programmable Power Supply) feature for their fastest mode, so check whether your phone lists PPS.
Multi-port chargers
Multi-port chargers share their total wattage between ports. A “65W” charger may give 65W from one port but split into 45W and 20W with two devices attached. Read the per-port breakdown on the packaging. Gallium nitride (GaN) chargers pack more power into a smaller body, but safety certification marks matter more than the material.
Which USB-C Cable Should You Buy?
A strong charger is held back by a weak cable. USB-C cables differ in two main ways.
- Power rating. Standard cables carry up to 60W (3A). Cables rated for 100W or 240W contain an electronic marker chip that tells the charger they can handle 5A.
- Data speed. Many charging cables only support USB 2.0 (480 Mbps), which is fine for charging but slow for large video transfers. USB 3.x, USB4 and Thunderbolt cables move data far faster.
Pick a length that matches where you charge. A 1-meter cable keeps a desk tidy, while 2 meters is handier at a bedside. Braided jackets and reinforced strain relief near the plug usually survive daily bending better.
How Does Qi2 Wireless Charging Work?
Wireless chargers move power between a coil in the pad and a coil in the phone. Qi is the long-standing standard from the Wireless Power Consortium, and Qi2 adds a Magnetic Power Profile so the phone snaps into the right spot. Better alignment means less wasted energy, less heat and steadier speeds.
The first Qi2 tier supports up to 15W, and a newer 25W tier has followed 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, card wallets or metal plates can block or slow charging.
- If your phone lacks magnets, a Qi2-ready magnetic case can add them.
- Stands keep notifications visible, while flat pads suit bedside tables.
Power Banks and Air Travel Rules
Power bank capacity is listed in milliamp-hours (mAh), but airlines use watt-hours (Wh). 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 output is lower than the label because some energy is lost in conversion.
Flying with a power bank
According to the FAA’s PackSafe guidance on lithium batteries, spare lithium batteries and power banks belong in carry-on baggage only. If your carry-on is checked at the gate, take the power bank out and keep it with you.
- Lithium-ion batteries up to 100Wh are allowed without airline approval.
- Batteries over 100Wh and up to 160Wh need airline approval, with a limit of two spares per person.
- Protect the terminals from short circuits, for example with the original packaging or a pouch.
- Damaged or recalled batteries should not fly unless they have been made safe.
Many airlines set stricter limits, including on how many power banks you can bring or whether you can use them in flight, so check with your carrier first. For safety at home, stop using any battery that swells, smells odd or gets unusually hot.
Cases and Screen Protectors
A case is the cheapest insurance your phone can get. Match it to your habits rather than to the most rugged option on the shelf.
- Slim cases add grip and scratch protection with little bulk.
- Rugged cases add thicker corners and raised edges for frequent drops.
- Wallet and folio cases keep cards close but can interfere with wireless charging.
- Magnetic cases add Qi2 or MagSafe-style magnets for mounts and chargers.
For screen protectors, tempered glass is the usual choice. A “9H” label describes a pencil hardness test, not a promise that the glass cannot crack. An installation frame and good case compatibility keep the edges from lifting.
Phone Accessory Checklist

|---|---|---|---|
| Wall charger | USB PD wattage, PPS support | Per-port wattage listed, safety marks | Vague “fast charge” claims with no wattage |
| USB-C cable | 60W, 100W or 240W rating; data speed | USB-IF certification, sturdy connectors | Unlabeled cables for laptop charging |
| Wireless charger | Qi or Qi2, wattage | Qi2 certification, magnetic alignment | No certification, poor heat control |
| Power bank | mAh and Wh, output wattage | Wh printed on the label, PD output | Capacity claims too big for the size |
| Case | Fit, material, magnets | Raised edges, exact cutouts | Blocking wireless charging you rely on |

Buying Tech Accessories Safely
Because Alaikas.com does not run a checkout, every purchase happens with an independent seller or retailer. Our step-by-step guide to buying through the site explains that process, and the wider marketplace section covers how sellers fit in.
For chargers and batteries in particular, skip listings with no clear specs, no safety marks or no real seller address. Uncertified power accessories are the category most likely to overheat or fail early.
Once your phone is sorted, the Alaikas.com team has more help for the rest of your gear: our guide to wireless earbuds and headphones and our walkthrough of a comfortable work-from-home desk both pair well with a good USB-C charger.
Frequently Asked Questions
Does Alaikas.com sell phone chargers and cases?
No. Alaikas.com does not sell, stock or ship products. Our guides explain the features and standards that matter, such as USB-C Power Delivery and Qi2, so you can compare listings yourself. You buy directly from independent sellers and retailers, so their prices, shipping and return policies apply to your order.
Will a higher-wattage charger damage my phone?
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 only draws about 25W from a 65W charger. The real risk comes from uncertified, very cheap chargers that cut corners on safety components.
How do I work out a power bank's watt-hour rating?
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 banks print the Wh figure on the label, which is the number airline staff look for.
Is Qi2 the same as MagSafe?
Not exactly. Qi2 is an open standard from the Wireless Power Consortium, and its Magnetic Power Profile builds on the magnetic alignment design Apple contributed from MagSafe. In practice, Qi2 chargers and Qi2-ready phones snap together in a similar way. Older Qi pads without magnets still work, but alignment and speed vary more.
