📋 目次
1How many times can an emergency battery charger actually charge my phone?
It depends on the capacity — a 10,000mAh charger typically gives you 1-2 full charges for a smartphone, while 20,000mAh or higher gives 2-4 charges. Check the actual mAh rating rather than marketing claims, since some power is lost during charging.
2What's the difference between a power bank and an emergency battery charger?
They're essentially the same thing — an emergency battery charger is just a portable power bank designed for backup situations. Look for ones with multiple charging cables built-in or included, since that's what makes them truly emergency-ready.
3Should I buy a charger with wireless charging or stick to wired?
Wireless charging is slower and less efficient, so skip it for emergencies unless you specifically need it. A solid wired connection with fast charging support (like Quick Charge or USB-C) will get you back to full power faster.
4What capacity should I get for regular daily backup?
A 10,000mAh to 15,000mAh charger handles most daily needs and fits in a bag or pocket easily. Go for 20,000mAh or higher only if you regularly charge multiple devices or spend days away from outlets.
5Does it matter which brand I choose, or are they all similar?
Quality matters more than brand name — look for one with good reviews on safety features and durability rather than just price. Check if it has overheat protection and comes with warranty coverage, since a cheap unit that dies after a year isn't a bargain.
