Baseus 145W vs 45W Mini Power Bank for Laptop and Phone Bags
This guide may earn a commission when readers buy through affiliate links.
Quick verdict
The Baseus 145W model makes more sense if your bag really does have to cover laptop time away from outlets.
The Baseus 45W Mini is easier to live with when you mostly want a lighter phone-and-tablet battery you will actually keep carrying.
Skip both if the cleaner answer is still a charger at one desk, not another battery in the bag.
Portable batteries get judged by wattage first and daily carry second. That is usually backwards. The more useful split is simple: are you trying to keep a laptop alive away from outlets, or are you just looking for a battery that feels easy enough to throw into the bag every day?
If this were my bag, that is where I would start. Not with the bigger number. With the question of whether I would still want to carry the thing a week later.
The trade-off is obvious. The 145W pack asks for more room and more commitment. The 45W Mini is easier to justify, but it can start feeling small the minute the bag becomes work-first instead of phone-first.

Baseus 145W power bank — Buy this if
Your bag has to cover a laptop and phone on the same day, not just rescue a phone on the train home.
Baseus 45W Mini — Buy this if
You mainly want a battery for phone-and-tablet top-ups and only occasional light laptop help.
Skip both if
You mostly work from one desk and the better fix is still a charger, a cleaner cable setup, or more outlet access.
If you are still stuck on battery versus wall charger, the 100W four-port charger guide is the cleaner follow-up.
- Be honest about whether your laptop actually needs battery help away from outlets, or whether this is mostly a phone problem.
- Check your bag tolerance first. A battery that feels too heavy after three days usually stops making the trip.
- Treat ratings, sold counts, and listing images as live signals from the checked date, not fixed promises.
Baseus 145W power bank
On the checked date, the listing was still under BASEUS Official Store with a 96.8% rating and 2,983 visible sales. More important than the numbers, though, is the way the product is positioned. This one is clearly trying to be the battery you pack when the laptop matters, not the battery you buy because 145W looks good in a headline.

Best for
Laptop-and-phone carry where you do not want the battery question hanging over the day.
Why it earns the bigger footprint
The appeal here is not subtle. It gives a work bag more room to breathe when the laptop is part of the plan, and the built-in cable story helps keep that setup cleaner than carrying a loose pile of charging extras.
Why I still would not call it the easy default
It is the bulkier answer, and bulky gear gets judged every single day. If most of your week is still phone-first, this can turn into the battery you admire more than the one you enjoy carrying.
Check this before ordering
Ask whether laptop backup is part of your normal routine or just a scenario you worry about. If it is mostly hypothetical, the extra size starts looking expensive in bag space very quickly.
Pros
- Safer choice for laptop-first carry
- Official-store listing with visible sales depth
- Built-in cable helps keep the bag simpler
Cons
- Bulkier than a small top-up bank
- Too much battery if phone charging is the main job
- Harder to justify when most days stay near power

Baseus 45W Mini
On the checked date, this listing was also under BASEUS Official Store, with a 97.7% rating and 6,307 visible sales. The more convincing part is not the spec sheet. It is that the 45W Mini knows exactly what it is trying to do: stay small, stay easy to bring along, and solve the charging problem most people hit more often.

Best for
Daily carry that leans phone-first and only occasionally asks the battery to help a laptop.
Where it feels right immediately
The case for the Mini is easy to understand once the bag is already crowded. It asks for less space, less mental negotiation, and less commitment. That matters more than headline wattage when the battery has to earn its spot every morning.
Where it can let you down
The small size is also the warning label. The moment your travel or café days start leaning laptop-first, the Mini stops feeling clever and starts feeling a little too optimistic.
One thing to check honestly
If you keep saying you need laptop backup, make sure that is actually true. The Mini is the smarter carry only when the laptop ask stays occasional and light.
Pros
- Easier to justify in a small bag
- Higher visible sales signal on the checked date
- Cleaner fit for everyday phone-first charging
Cons
- Not the right answer for serious laptop backup
- Smaller margin on long unplugged days
- Can feel too limited if the bag is work-first

Bottom line
Pick the Baseus 145W power bank if your bag genuinely has to protect laptop uptime away from outlets and you can live with carrying the bigger pack.
Pick the Baseus 45W Mini if the smarter everyday carry matters more and your charging life is still mostly phone-first.
Skip it if: Skip both if the cleaner fix is still a charger on your desk, not another battery in your bag.
Is the 145W model automatically the better buy because the number is bigger?
No. It is the better buy only when the bag really has to cover laptop time away from outlets. If that use case is weak, the extra bulk becomes the bigger story.
Which one is easier to recommend to most work bags?
The 45W Mini is easier to recommend broadly because the carry penalty is lower. The 145W model starts making more sense once laptop battery anxiety becomes a repeated part of the week.
Check laptop wattage, airline carry rules, bag weight, USB-C cable rating, and whether phone-only charging is enough.
For AliExpress-style picks, also check seller rating, review count, shipping estimate, plug or cable type, and whether returns are worth the hassle.

When should I skip both options?
Skip both if your current charger already covers the devices you carry every day.
