Detailed Review — Real-World Use
If you travel with a laptop for work or frequently shoot video/photo on location, portability and charging speed matter. The Baseus unit offers true laptop-grade output on a relatively compact device. The high-watt USB-C PD port can handle many 45W–100W laptops and even some 140W devices (check your laptop's acceptance of PD vs proprietary chargers).
In daily use, I found the USB-C ports handy for fast charging a MacBook Air or charging an iPad Pro while also topping up phones via USB-A. The power bank intelligently splits power between ports when multiple devices are connected — useful during travel when you want to charge a laptop and phone simultaneously.
Recharging the power bank itself is fast when using a high-watt PD charger — a 100W wall charger can bring the unit back to a useful level much faster than older power banks. Build quality is solid: matte finish, secure USB ports, and cooling vents for long charge sessions. It’s heavier than a phone battery, naturally, but still far more portable than carrying a laptop charger plus phone charger.
Pros & Cons
Pros
- True laptop-capable USB-C PD up to 145W
- Large 20,800mAh capacity for multiple charges
- Multiple ports for simultaneous charging
- Fast recharge when paired with a high-watt PD wall charger
- Good safety features and thermal control
Cons
- Heavier than phone-sized power banks
- Not all laptops accept full 145W via PD — check compatibility
- Price higher than basic portable chargers
How to Choose & Compatibility Tips
- Check your laptop’s power input: If your laptop requires a proprietary charger >100W, confirm it supports USB-C PD at that wattage.
- Balance weight vs capacity: 20,800mAh is a great middle ground for 1–2 days of light laptop use and multiple phone charges.
- Carry a high-watt PD wall charger: To recharge the bank quickly, use a 60W–100W USB-C PD charger.
- Look for certifications: UL/CE/FCC markings and manufacturer safety statements matter for airline travel and reliability.
FAQ
Can this power bank charge my MacBook Pro?
Most modern MacBook Pro models accept USB-C PD. This Baseus unit’s 145W capability should handle many MacBook Pro variants, but check your specific model’s PD acceptance (some older Macs prefer Apple’s charger). When in doubt, look up your model’s max PD input.
Is it allowed on airplanes?
With a battery under 100 Wh, airlines allow carry-on. A 20,800mAh pack generally equals ~74 Wh — under the 100 Wh limit. Still, carry it in hand luggage and review airline rules before flying.
How many times will it charge my phone?
Practical phone charges depend on phone battery size and conversion loss, but expect 3–5 full charges for typical smartphones (3000–4500mAh), and 1 full laptop top-up depending on laptop battery capacity.
How long does it take to recharge the power bank?
Using a 100W PD wall charger, you can recharge to a useful level much faster (often in 1.5–3 hours). With lower-watt chargers it will take longer — check Baseus specs for exact recharge times.

Final Verdict
The Baseus 20800mAh 145W power bank is an excellent choice for professionals and travelers who need reliable, laptop-capable portable power. It strikes a good balance between capacity, charging speed, and portability. If you need multi-device charging or emergency laptop top-ups without lugging a full charger, this unit is worth considering.
