Frequently asked questions

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.

In this category you will find batteries and cells for many uses: replacement phone batteries, lithium polymer (LiPo) packs for hobby devices, battery chargers and battery protection boards (BMS). The range includes AmpSentrix replacement batteries for iPhone models, Gens Ace LiPo packs for airsoft use and SkyRC chargers for different cell types. The most important criterion is compatibility: a replacement phone battery has to be intended for your particular device model, and the right size alone is not enough. Capacity, that is the mAh figure, tells you how long the battery lasts between charges. With hobby packs it is worth checking the voltage and cell count (3S, meaning 11.1 V, for example), the C rating that describes discharge current, and the connector type, such as a T-connector, so that the battery fits your device as it is. When choosing a charger, make sure it supports your battery's cell type and cell count - that way charging is safe and the battery keeps its condition longer.
