Choosing a 100W Laptop Power Bank: TSBar 20,000mAh PPS
By Robert PetersonYour workday can move beyond the nearest outlet. The Techsmarter TSBar 20,000mAh 100W PPS power bank brings up to 100W USB-C output, a 74Wh battery pack and a digital display to your mobile setup. It is a portable charger built around a useful combination: laptop power for work and PPS fast charging for compatible phones.
Understand the 100W rating
The main USB-C port supplies up to 100W to compatible devices. USB Power Delivery matches the output to your device, while the second USB-C connection adds a convenient place for a supported phone or tablet.
Match your laptop and cable
Confirm that your exact laptop supports USB-C Power Delivery and check its required voltage profiles and power. Use a cable rated for the output you need. A laptop under heavy load may use more power than it does while idle.
Choose capacity for your routine
The 20,000mAh capacity provides stored energy for use away from an outlet. The number of charges depends on your device and charging conditions. Compare dimensions, weight and recharge requirements when deciding what to carry.
Charging phones and other devices
PPS brings one-hour fast charging to compatible phones using the supported port, cable and charging mode. That makes this laptop power bank useful for quick phone charging during the same busy day.

*Illustrative estimates use a 5,000mAh phone battery at 3.85V, power-bank cells at 3.7V and an assumed 75% energy transfer: bank mAh × 3.7 ÷ 1,000 × 0.75 ÷ 19.25. Recharge counts vary with phone, charging method and use; wireless charging can yield fewer charges. A decimal includes a partial recharge.
Use a cable and charging mode supported by your device. Power is shared when several outputs are in use. A dash means the one-hour phone-charging feature is unspecified for that model.
TSBar 20,000mAh 100W: a port-by-port starting point
This laptop portable charger combines a 20,000mAh battery pack with a digital charge display. Its model-specific port mix is the reason to compare it with the 65W version, even though both have the same advertised capacity.
| Listed feature | TSBar 20,000mAh 100W PPS | How to use the information |
|---|---|---|
| Battery energy | 74Wh | Compare with your laptop’s battery energy; delivered energy is lower after conversion losses. |
| Primary USB-C | Up to 100W | Use this output for a compatible laptop with a suitable 5A cable. |
| Second USB-C | Up to 30W | Convenient output for a compatible phone or tablet. |
| USB-A | Up to 22.5W | For compatible USB-A devices. |
| Recharge estimate | Approximately 1 hour 50 minutes in the product listing | Use the supported USB-C input adapter and cable. |
The main 100W USB-C connection suits a compatible laptop, while the additional ports add flexibility for smaller devices. Available power is shared when multiple outputs are in use.
As a planning example, topping up half of a 50Wh laptop battery takes 25Wh at the battery. Allow extra stored energy for conversion and the work the laptop is doing while connected. The TSBar’s 74Wh capacity provides a useful reserve for a mobile work kit.

Questions about this laptop battery pack
Does 100W mean a larger battery than the 65W model?
No. The linked 20,000mAh models have the same advertised capacity; the maximum output and port mix differ.
Is the recharge estimate a laptop charging time?
No. Recharging the power bank and charging a connected laptop are different processes.
One charger that earns its place in your work bag
A main USB-C output for your laptop, a second USB-C connection for a phone or tablet, and a digital display make this a versatile everyday choice. PPS adds one-hour fast charging for compatible phones using the supported cable and charging mode. Choose the TSBar 100W when you want laptop capability and convenient phone charging in the same battery pack.
