It's important to have a good charger. The right charger not only ensures your phone charges quickly enough but also extends the lifespan of your devices. You'll need your charger often: when you want to charge your devices at home, need a quick boost on the go, or at the office while you're not using them. This blog post explains what to look for when buying a charger, so you can get the best one for your needs.

1. Charging time

If you need to give your phone a quick boost, a fast charger is handy. A nearly empty phone won't get you very far, of course. Fortunately, there's a wide range of fast chargers available, but what are the requirements for a good fast charger?

The most important factor in determining charging speed is the maximum power ( watts ). A standard charger often delivers 5-10 watts, while fast chargers are available from 18 to 140 watts. However, more power doesn't always mean faster charging: up to about 65 watts, you'll notice a significant difference in charging speed.

It's also important that the technology used is up to par: Power Delivery (PD), Quick Charge (QC), or GaN technology support safe fast charging. This way, your fast charger automatically adjusts to your phone's charging capacity, even if it delivers more power than your device can handle.

Charging time of the average smartphone (with a battery around 4500 mAh)

Charger power Suitable for Estimated charging time 0 → 100 % Comments
5 W Standard old USB chargers ± 3 – 3.5 hours Very slow; barely enough during use
22.5 W Modern fast chargers (e.g. Huawei SuperCharge, PD 20–25 W) ± 1 h 15 min – 1 h 30 min Popular for smartphones with USB-C
30 W Universal PD chargers, iPhone 15 Pro / Pixel / Samsung ± 1 hour Good balance between speed and heat
65 W High-end PD/GaN chargers ± 35 – 45 min Often limited by the device itself
140 W Laptop chargers (e.g. MacBook Pro) ± 35 min (only if the device can handle this) Older smartphones rarely use more than 30W; overkill

2. Charger for on the go

When you're on the go and your phone is running low, you want a compact solution. For travel, we always recommend a power bank. You can pre-charge it at home and use it to charge your phone multiple times while on the go.

To determine how often you can charge your phone with a particular power bank, you need to know your phone's capacity (expressed in mAh). You usually won't find this information in your phone's settings, but you can find it online (for example, search for "phone model mAh").

The calculation is simple: first multiply the power bank's capacity by 0.85 (MOJOGEAR power banks are 85% efficient, the remaining 15% is energy loss) and then divide this by your phone's capacity. If you have a 10,000 mAh power bank and an iPhone 14 (3,279 mAh), you can fully charge it more than two and a half times.

3. Wireless charging

Do you find it annoying to constantly deal with cables, or do you never have the right one with you? Then a wireless charger is the ideal solution.

A wireless charger uses induction (usually Qi or Qi2 standards) to transfer power wirelessly. You simply place your phone on the charger, and charging starts automatically.

Most modern smartphones from brands like Apple, Samsung, and Google support wireless charging. However, be sure to check if your device does, as not every model has this feature. Apple uses MagSafe, but it's only supported on the iPhone 12 and later models.

Also, pay attention to the maximum wireless charging power. Many phones charge wirelessly up to 7.5 or 15 watts, but some models (such as recent Samsung Galaxy devices) support fast charging up to 25 watts with a compatible Qi2 charger.

One advantage of wireless charging is its convenience and the clean look it creates on your desk or nightstand. The downside is that it's a bit slower than wired charging, and the phone needs to be properly aligned with the charging coil. Magnetic chargers, such as those with MagSafe or Qi2 (these have a magnet), largely solve this problem.

4. The right cable

When charging your phone, it's not just the charger itself that's important, but also the cable. A good cable provides sufficient power for fast charging and prevents heat or voltage loss.

The most important thing is that you choose the right connection for your phone:

  • USB-C: the current standard for almost all Android devices, tablets and new iPhones (from iPhone 15).
  • Lightning: For iPhone 14 and younger, and some accessories.
  • Micro USB: Older technology, still used in cheap devices or accessories.

On the other end of the cable, you'll usually find USB-A or USB-C. This plugs into the charging block (adapter). New chargers almost always use USB-C because it supports more power (up to 240W with USB-C 2.1).

Always choose an approved cable from a trusted brand like MOJOGEAR, Apple, or Samsung. Poorly manufactured cables can overheat or limit charging speed.

When charging, three factors together determine the speed:

  1. The maximum power of the charger
  2. The maximum power the cable can handle
  3. The maximum charging capacity of the device

The weakest link determines the speed. If you have a 65W charger and a 100W cable, but your phone accepts 30W, you're still charging at 30W.

Tip: For laptops or tablets, always use a cable that is suitable for Power Delivery (PD) and check that the cable is certified for the correct wattage class.

5. Charge multiple devices simultaneously

Looking for a charger that can charge everything from your phone and smartwatch to your tablet and laptop? Then a high-output multi-port charger is the best choice.

These chargers combine multiple USB-C and sometimes USB-A ports, allowing you to charge all your devices simultaneously with a single adapter. Thanks to modern GaN technology, they remain compact, cool, and efficient. This allows you to charge your devices quickly and safely.

A full-featured charger with, for example, 100W or 140W power automatically distributes power across your devices. This allows you to effortlessly charge your laptop (e.g., 65W) while simultaneously charging your phone and earbuds.

Useful for:

  • At home or at the office: one charger for all your devices
  • When traveling: take fewer loose adapters with you
  • Space in your power strip: You can charge more devices on a multi-port charger, giving you more space to use other plugs.

When purchasing a laptop, pay attention to the power distribution per port. Not every port provides the same amount of wattage. Therefore, check that the port your laptop connects to supports sufficient power (usually 60W or more).

A good, complete charger saves space, is more efficient and prevents you from having to work with multiple separate adapters.

Conclusion

There are many different ways and types of chargers to charge your devices. Below are the 5 most important tips at a glance:

  • Pay attention to the power of your charger: how quickly do you want your phone to charge?
  • Pay attention to the size: when do you use the charger most often and how much space can it take up?
  • Do you want a wireless charger or not?
  • Note that the cable you use may not always handle the same power as your adapter. Keep in mind that if your cable has a lower power rating, your phone will charge more slowly.
  • Consider how many devices you want to charge simultaneously with one charger

Before buying a charger, it is important to know the capacity (mAh) and maximum power (Watt) of your phone.
