My Buying Guides on Portable Chargers For Iphone 15

When I was looking for the perfect portable charger for my iPhone 15, I realized there are several key factors to consider to make the best choice. Here’s what helped me decide, and I hope it helps you too.

1. Battery Capacity (mAh)

The first thing I checked was the battery capacity, measured in milliampere-hours (mAh). Since the iPhone 15 has a battery around 3,200 mAh, I looked for a portable charger with at least 10,000 mAh. This way, I could get multiple full charges on the go without worrying about running out of power quickly.

2. Charging Speed and Power Delivery

Fast charging was a must for me. I made sure the portable charger supports Power Delivery (PD) and can deliver at least 20W output. This ensures my iPhone 15 charges quickly, especially when I’m in a hurry. Also, I checked if the charger supports USB-C PD since the iPhone 15 uses a USB-C port.

3. Portability and Size

Since I carry my charger everywhere, I wanted something compact and lightweight. I compared different models and chose one that fits easily in my pocket or bag without adding much bulk.

4. Number and Type of Ports

I often need to charge multiple devices, so I looked for a portable charger with more than one output port. Having at least one USB-C and one USB-A port gave me flexibility to charge my iPhone 15 and other gadgets simultaneously.

5. Build Quality and Safety Features

Durability matters, so I picked a charger with a sturdy design and good reviews on build quality. Plus, I made sure it has safety features like overcharge protection, short circuit protection, and temperature control to keep my phone safe.

6. Price and Brand Reputation

I balanced my budget with quality by choosing a reputable brand known for reliable portable chargers. Sometimes, paying a bit more upfront saves money and hassle in the long run.

7. Extra Features

Some chargers come with handy extras like built-in cables, LED indicators, or wireless charging pads. I considered these features but prioritized core performance first.
