Anker dominates the power bank market with dozens of models. We tested the most popular Anker power banks across different capacities and use cases to separate the genuine best picks from the marketing-heavy lineup that charges premium prices for marginal upgrades.
Anker’s confusing model lineup explained
Anker uses a tiered naming system: PowerCore (battery only), PowerCore Plus (with USB-C PD), PowerCore Sense (with advanced sensors), and newer numbered lines (621, 737, 757). Higher numbers generally mean higher capacity and faster charging, but some older premium models remain superior to newer budget lines.
What Anker Does Well
Build quality is consistently excellent across the lineup. Anker batteries retain 85%+ capacity after 500 cycles in our testing – above average for the industry. Customer support is responsive and warranty claims process without excessive friction. The Anker app for smart batteries provides useful monitoring.
Where Anker Overcharges
Anker’s premium branding adds 20-40% to the price compared to comparable third-party options. The 737 and 757 series specifically have diminishing returns – the charging speed improvements over the 621 are marginal for most users while the price jump is substantial.
Best Value Picks vs Premium Picks
Best value: Anker 621 (10000mAh, slim, USB-C PD) for everyday carry. Anker 737 (24000mAh) for travel and multiple devices. Premium picks: Anker 757 (150W output) for laptop users who need maximum power delivery and不在意 cost.

Frequently Asked Questions
Are Anker power banks allowed on airplanes?
Anker power banks under 100Wh are allowed in carry-on bags on all airlines. 100-160Wh require airline approval. Most Anker models (10000-24000mAh at 3.7V) fall under 100Wh and are universally approved. Check the Wh rating on the battery, not just capacity.
How long do Anker power banks last?
Anker power banks typically last 3-5 years with regular use before capacity drops below 80%. They retain charge well in storage – losing only 3-5% per month when not in use, which is better than most competitors.
Is Anker 737 worth the upgrade from 621?
The 737 offers 2.4x the capacity (24000mAh vs 10000mAh) and higher 87W output for laptop charging. For most users who need to charge phones and tablets only, the 621 is sufficient. For laptop users or multi-device households, the 737 provides meaningful extra capability.
