Best Power Banks (2025): Top Picks for Remote Workers
A good power bank keeps your laptop and phone charged through flights, co-working days, and power outages. The difference between a 20,000mAh phone-sized power bank and a capable laptop power bank often comes down to USB-C PD wattage — you need at least 60W to meaningfully charge a laptop.
We selected these power banks based on official capacity, USB-C Power Delivery output wattage, input charge speed, form factor, and practical use for laptop-charging remote workers. We selected these based on official specifications, compatibility, availability, price context, and practical workflow fit.

Anker 737 Power Bank (26,800mAh)
Best for: Workers who need to charge a laptop at least once from a power bank
140W output means it can charge a MacBook Pro 16″ or high-end Windows laptop at full speed. The real-time wattage display on the screen shows exactly how fast each device is charging. 26,800mAh provides roughly 1.5 full MacBook Air charges.
Key specs: 26,800mAh, 140W output (USB-C), 65W input, 3 ports (2× USB-C, 1× USB-A), real-time wattage display
Caveat: Heavy at around 670g — more of a desk/bag item than something you carry in a jacket pocket.
Price: Premium; top-tier laptop power bank.
Anker Prime Power Bank (27,650mAh)
Best for: Power users who want Anker’s flagship capacity with rapid self-recharge
250W output covers virtually any USB-C laptop. The 170W input recharges the bank itself from empty to full in 37 minutes — useful if you’re in an airport lounge for an hour before a long flight.
Key specs: 27,650mAh, 250W output (highest on device), 170W input (charges itself in 37 minutes), 3 ports, LED display
Caveat: Requires the matching 170W charger for fast self-recharge. Heavy — 670g.
Price: Top-end flagship pricing.
Anker PowerCore 24K
Best for: Users who want solid laptop charging capacity in a more affordable option
100W USB-C output charges most laptops at or near full speed. The 24,000mAh capacity covers one full MacBook Pro 14″ charge with capacity to spare for a phone.
Key specs: 24,000mAh, 100W USB-C output, 30W input, 3 ports (2× USB-C, 1× USB-A)
Caveat: 30W input means slower self-recharge than the flagship models — plan for overnight charging.
Price: Mid-range; balanced value for most users.
Anker A1651 (10,000mAh Slim)
Best for: Minimalists who primarily need to keep their phone charged and want something truly pocketable
At roughly the size and weight of a large phone, this is the power bank you’ll actually carry daily. 20W keeps phones topped up at full speed. Useful as a supplemental pack alongside a laptop charger.
Key specs: 10,000mAh, 20W USB-C output, 2 ports (1× USB-C, 1× USB-A), slim lightweight form factor
Caveat: 20W is not sufficient to charge most laptops — phone-only charging capacity.
Price: Budget-friendly; best entry-level pick.
Baseus Blade Laptop Power Bank (100W, 20,000mAh)
Best for: Budget-conscious buyers who want 100W laptop charging at a lower price than Anker
The Baseus Blade has a flat, wide form factor that slides easily into a laptop bag alongside a notebook. 100W USB-C output charges most laptops at full speed, and the digital display shows remaining capacity as a percentage rather than just LED dots.
Key specs: 20,000mAh, 100W USB-C output, USB-A port (22.5W), digital percentage display, 74Wh (airline-compliant)
Caveat: 74Wh capacity is less than the 737 or Prime — roughly one full MacBook Air charge. Less buffer than the higher-capacity Anker options.
Price: Budget to mid-range; best price-per-watt for 100W laptop charging.
How to choose a power bank
- USB-C PD wattage for laptops: You need at least 60W output to meaningfully charge a laptop. 100W or higher covers virtually all USB-C laptops. 20W is phone-only.
- Capacity vs. weight tradeoff: Higher capacity means heavier. 24,000–27,000mAh is the sweet spot for laptop charging. 10,000mAh is fine for phones only.
- Self-recharge speed: A 27,000mAh bank with 30W input takes 9+ hours to recharge. For frequent travelers, fast input (100W+) matters as much as output.
- Port count: Two USB-C ports allow simultaneous laptop and phone charging. Three-port designs add a USB-A for older accessories.
- Airline regulations: Most airlines allow carry-on of power banks up to 100Wh. 27,000mAh at 3.7V = ~100Wh — exactly at the limit. Always check your specific bank’s Wh rating on the label.
