Does fast charging damage the battery?

No. Phones made from 2020 onwards manage charging speed and temperature themselves, so fast charging is safe for everyday use. If you want to stretch battery life as far as possible, wired charging at a moderate 10–20 W is the gentlest option.

Can I use any USB-C charger?

Yes, USB-C is a common standard. Fast charging, however, only works with a compatible charger (Quick Charge, USB-PD, SuperVOOC). Always use a certified charger — an uncertified one charges slowly and can be unsafe.

Wireless or wired charging — which is better?

Wired is faster and more efficient, because less energy turns into heat. Wireless is more convenient but slower and runs warmer. For long-term battery health wired is slightly better, though with current technology the difference is small.

How powerful a charger do I need?

It depends on the phone: iPhone accepts 20–27 W, Samsung Galaxy 25–45 W, and OnePlus and Xiaomi flagships 80–120 W. There is no need to buy the most powerful one — 20–30 W is enough for most phones and works with everything.

What power bank capacity should I choose?

10,000 mAh covers normal use — two to three full charges. If you travel a lot, 20,000 mAh is the better choice. Check the output power too: 20 W or more means the power bank can fast charge.

Description

Energizer Ultimate A38QMU is a silver compact GaN travel wall power adapter with one USB-C port, one USB-A port and interchangeable plug heads for EU, UK and US sockets.

With compatible equipment, USB-C Power Delivery provides up to 20 W and USB-A Quick Charge 3.0 up to 18 W, for a combined maximum of 38 W. The connected devices and cables determine the actual power and supported protocol.
The input range is 100–240 V AC at 50–60 Hz. The plug heads only adapt the physical socket shape; they do not convert voltage, so every connected device must support the local mains supply.
The adapter measures approximately 34 × 37 × 46 mm and weighs about 83 g. GaN technology enables a compact design, but the housing can still become warm in normal use.
Fit the correct plug head before connecting to the socket. Keep the unit dry, leave ventilation space and stop using it if the housing, plug or port is damaged or unusually hot.

The package contains one A38QMU wall power adapter and EU, UK and US plug heads. USB cables and connected devices are not included.
