We tested 13 power banks to help you choose the best one
We tested 13 power banks from Anker, Belkin, Baseus, Cuktech, and Sharge, tracking charge times, output, temps, and capacity to see which actually hold up.
When it comes to power banks, many people simply opt for one with enough ports, capacity, and output to keep their devices charged on the go. However, a few factors can make a significant difference. We tested 13 power banks, ranging from slim, single-port 5,000 mAh units outputting 22W to more robust multi-port 25,000 mAh models capable of delivering 220W across multiple ports.
Prices varied between $24.99 for the Cuktech CP12 (10K/20W) and $129.99 for the top-of-the-line Anker Prime (A110B) 20K/220W. Some models come with integrated USB-C cables, others include removable cables, while some provide no extras in the box. Design varies widely, from simple grey boxes to larger stand-up units and even transparent chassis.
The choice depends on individual needs, budget, and personal preference. Generally, higher output and capacity come with a higher price tag. When selecting a power bank, consider factors such as price, size, safety features, and the number of ports. Key considerations include supporting modern charging standards like USB-PD (Power Delivery) and/or Qualcomm Quick Charge for fast charging, ensuring the device can handle the required wattage for your specific device (e.g., Asus Zenbook Duo requires around 90W), and being aware of the difference between rated and actual capacity.
Rated capacity is based on a 3.7V battery, so actual capacity varies based on the voltage your device requires. Higher voltage and output charging can reduce usable capacity by up to 20%. Pass-through charging, which allows charging the bank and powering devices simultaneously, is another valuable feature. Most tested power banks support this feature, except for the Cuktech CP12 and Baseus PicoGo Air.
Renowned brands like Anker, Sharge, Cuktech, Belkin, and Baseus generally prioritize safety with multiple protection measures against overcharging, over-current/voltage, over-temperature, and more. However, off-brand devices may lack these safety features and pose potential hazards. Always verify the UL/CE (or CCC for China) certification and safety features before purchasing.
During testing, we evaluated build quality, size, weight, and port count/type, alongside capacity and output ratings, fast-charging capabilities, and safety features. This information helps reveal the advantages and disadvantages of each power bank, including cost per mAh, actual capacity versus listed capacity, port count, temperature, and protective measures.
