How to choose power banks in Canada
Two numbers do most of the work: capacity, measured in milliamp-hours (mAh), and output, measured in watts (W). Capacity decides how many top-ups you get; output decides how quickly each top-up happens.
Capacity: 10,000 or 20,000 mAh?
The Xiaomi Power Bank 10000mAh 22.5W Lite suits everyday carry in a backpack or purse. The REDMI 20000mAh 18W Fast Charge Power Bank holds twice the charge, which is handy for camping, road trips or keeping a phone and tablet going on the same day. No power bank delivers its full rated capacity to your device, because some energy is lost to voltage conversion and heat, so plan on fewer full charges than simple math suggests.
Output: why watts matter
If your device and the power bank share a compatible fast-charging standard, they negotiate a higher speed; otherwise charging falls back to a standard rate. Either way, the result is capped by the lower of the two. The Lite model offers up to 22.5 W output, and the 20,000 mAh model offers 18 W fast charging. A phone rated for 100 W wired charging can only charge as fast as the pack allows, so expect slower top-ups than from a charger built for its full speed.
Which one should you pick?
- Daily commute or school bag: the 10,000 mAh Lite, for a quick midday boost with its higher 22.5 W output.
- Weekend at the cottage or a camping trip: the 20,000 mAh pack, so you can recharge several devices without an outlet.
- Families and shared use: the larger pack, since two phones or a phone and a tablet draw from it over the day.
Travel and winter tips
- Flying: in Canada, spare lithium batteries, including power banks, go in carry-on baggage, not checked luggage. Packs under 100 Wh are generally allowed. To estimate watt-hours, multiply mAh by the cell voltage (commonly 3.7 V) and divide by 1,000, then check the rating printed on the pack and your airline's rules.
- Cold weather: lithium cells lose capacity in the cold. Keep the pack inside your coat on the ski hill, and let a chilled pack warm to room temperature before recharging it.
- Cables: use a cable rated for the output you want; a worn or low-quality cable can limit charging speed.
- Storage: if a pack will sit unused for months, store it partly charged in a cool, dry place and top it up occasionally.

Accessories: frequently asked questions
How many times can a 20,000 mAh power bank charge my phone?
It depends on your phone's battery size and on conversion losses. Power banks never deliver their full rated capacity, so divide the pack's capacity by your phone's battery capacity and expect somewhat fewer charges than that number.
Can I bring a power bank on a plane in Canada?
Generally yes, in your carry-on bag only. Power banks under 100 Wh are usually permitted, but check the rating on the pack and your airline's rules before you fly.
Which power bank charges faster?
The Xiaomi Power Bank 10000mAh 22.5W Lite has the higher output at 22.5 W, compared with 18 W on the REDMI 20000mAh model. Actual speed also depends on your device and cable.
