Whether you’re commuting from Woodlands to the CBD, spending the day in back-to-back meetings, or just out café-hopping, chances are your phone battery won’t last the full day. And once your battery hits 10%, everything gets a bit more stressful — no more scanning to pay, no more checking bus arrivals, no more anything.
That’s why a reliable power bank is no longer just for “techies” — it’s something most of us carry every day.
But not all power banks are made equal. Some are slim and easy to carry around, while others pack serious charging power for laptops and tablets. Depending on your needs, it can be tricky to know what to look for.
We’ve reviewed the best power banks for different types of users — from students and office workers to travellers and heavy phone users — with honest pros, cons, and practical tips so you can pick the one that fits your daily life in Singapore.

Buying Guide - How to Choose a Powerbank in Singapore
Whether you're commuting across the island, working out of cafés, or just want to avoid that dreaded “low battery” ping before your next PayLah scan, a reliable powerbank makes everyday life a lot smoother. But with so many models out there, choosing the right one can get confusing.
Here’s a simple guide to help you find one that fits your actual lifestyle — not just the specs on paper.
How Much Do You Need?
This is the most obvious feature people look at, but bigger isn’t always better. If you're mostly charging your phone and earbuds once or twice a day, a 10,000mAh powerbank is enough. If you’re out the whole day or charging more than one device, go for 20,000mAh or more.
|
Capacity |
Best For |
Typical Use |
|
10,000mAh |
Short commutes, topping up a phone or earbuds |
1.5–2 phone charges |
|
20,000mAh |
All-day use, tablets, sharing power with others |
3–4 phone charges or 1–2 tablet charges |
|
25,000mAh+ |
Remote work, travel, charging laptops or tablets |
Up to 5 charges or 1 full laptop charge |
Many newer phones have batteries around 4,000–5,000mAh, so use that as a rough guide when calculating what size you’ll need.
Don’t Waste Time Waiting
Charging speed depends on the output power of the powerbank, usually measured in watts (W). If your phone supports fast charging and your powerbank doesn’t, you’re stuck charging at snail speed.
Look for USB-C PD (Power Delivery) or Quick Charge (QC) if you want faster, more efficient top-ups.
|
Output Power |
Suitable For |
Examples |
|
18W–30W |
Phones, earbuds, tablets |
iPhones, Samsung S series, iPads |
|
45W–65W |
Tablets and small laptops |
iPad Pro, MacBook Air, Surface Go |
|
100W–145W |
Full-sized laptops |
MacBook Pro, Lenovo X1, Surface Laptop |
Some power banks also support fast recharging, so the bank itself charges quicker too. This is useful for large-capacity models that would otherwise take 8–10 hours to recharge.
How Many Gadgets Do You Charge?
If you only ever charge your phone, you’ll be fine with one output port. But many of us are juggling phones, wireless buds, smartwatches, and maybe a second phone. Some powerbanks even let you charge three devices at once.
- 1 Port: Basic use, phone-only charging
- 2 Ports: Great for phone + one extra device
- 3 Ports: Best for multitaskers, shared use, or travel
Also, some power banks now include wireless charging pads — helpful when you’re at a café or meeting and want to charge without taking out a cable.
Will You Actually Carry It Around?
You could have the most powerful power bank in the world — but if it’s too heavy, it’ll just end up sitting at home.
Here’s how weight affects real-world usage:
|
Weight Range |
What It Feels Like |
Good For |
|
Under 250g |
Like a phone or wallet |
Light daily use, small bags |
|
250g–400g |
Compact umbrella or bottle |
All-day carry in a tote or backpack |
|
Over 500g |
Tablet or mini laptop |
Full gear setups, WFH, travel |
If you're usually carrying a backpack or work bag, a heavier model may not bother you. However, if you only bring a small cross-body or handbag, opt for something slim and light.
How Much Should You Spend?
Powerbanks range from $30 to over $150, but not everyone needs the most expensive model.
|
Price Range |
What You Can Expect |
|
$30–$60 |
Basic models, slower charging, fewer ports |
|
$60–$100 |
Mid-range with fast charging, USB-C PD, and good reliability |
|
$100+ |
High performance, digital displays, laptop charging, premium design |
For most people, something in the $60–$90 range strikes a good balance between features and cost. You only need to go above $100 if you’re charging laptops or carrying multiple devices every day.
Extra Features – Worth Considering
These features aren’t necessary for everyone, but they can make your daily charging experience more convenient.
- Digital battery display – More accurate than blinking lights; shows exact percentage.
- Built-in charging cable – Helpful if you always forget your cable, but make sure it matches your device (USB-C or Lightning).
- Wireless charging pad – Slower than cable, but convenient for bedside or café use.
- Pass-through charging – Lets you charge your phone while the powerbank itself is charging. Useful if you’re short on plug points.

If you spend half your life on the MRT or café-hopping, this wireless-capable powerbank is a lifesaver. No cables? No problem — just place your phone on top and it’ll start charging. It also has USB-A and USB-C ports if you prefer the wired way.
Great for short outings where you want something compact and fuss-free. Just toss it in your tote and go.
What sets it apart?
Wireless charging is rare in powerbanks under $100, and Anker does it well. It’s a “just works” device, which is why it’s popular among professionals and students alike.
Specs:
- Battery Life: 10,000mAh – about 1.5–2 phone charges
- Device Limit: 3 (1 wireless + 2 wired)
- Display: 4-LED battery indicator
- Ports: USB-C PD, USB-A, wireless charging surface
- Weight: ~250g
What to know:
Wireless charging only works if your phone supports Qi — newer iPhones and Samsung Galaxies are fine, but older phones won’t benefit. Also, the powerbank itself charges relatively slowly (no fast recharging), so don’t expect miracles if you're in a rush.
If you’re out all day and juggling multiple devices — phone, tablet, maybe even a portable fan — this powerbank is your best friend. High capacity and fast charging, all for less than $60? Solid deal.
What sets it apart?
You get 33W fast charging, 3 ports, and pass-through charging. That means you can charge your phone while the powerbank itself is being charged — a lifesaver in cafes with just one plug.
Specs:
- Battery Life: 20,000mAh – about 3–4 phone charges
- Device Limit: 3
- Display: LED battery status
- Ports: USB-C PD, 2x USB-A
- Weight: ~470g
What to know:
Although it supports 33W, your device needs to support PD for fast charging. Also, this isn’t a slim powerbank — it’ll take up space in smaller bags. Consider pairing with a short cable to reduce clutter.
The Zendure SuperMini doesn’t just work — it looks good doing it. Think metallic colours, rounded edges, and a finish that feels premium in your hand. Despite the small size, it still offers 20W PD charging — enough to power your phone fast.
What sets it apart?
It’s one of the few powerbanks that combines form and function at this size. It fits into any bag, any lifestyle, and still keeps your device charged.
Specs:
- Battery Life: 10,000mAh – about 1.5–2 phone charges
- Device Limit: 2
- Display: LED battery indicator
- Ports: USB-C PD (20W), USB-A
- Weight: ~180g
What to know:
Don’t expect it to charge tablets or laptops — this is strictly for phones, earbuds, and maybe a smartwatch. Also, the slick surface can get scratched easily, so you may want to keep it in a pouch.
This is Samsung’s own branded powerbank — and it’s made for Galaxy phones. You get 25W wired fast charging and 15W wireless, both optimised for Galaxy S and Z-series phones. It also plays nice with wearables like Galaxy Buds and Watch.
What sets it apart?
True integration with Samsung devices. If you use Samsung daily, this gives you the most efficient charge without messing around with settings or adapters.
Specs:
- Battery Life: 10,000mAh – about 2 phone charges
- Device Limit: 2–3 (1 wireless + 2 wired)
- Display: LED battery status
- Ports: USB-C PD, wireless pad
- Weight: ~234g
What to know:
It still charges iPhones or other Androids, but not at maximum speed. Wireless charging also needs a flat, stable surface — not ideal for MRT rides unless you secure it properly.
This one’s a sleeper hit. It's slim enough to slide into a jeans pocket or hide behind your phone in a small sling bag. If you’re the type who doesn’t want to carry “extra weight” but still wants backup juice for a phone, this is it.
What sets it apart?
The form factor. Most 10,000mAh powerbanks are chunky — this one feels like a flattened wallet. Perfect for light travel, errands, or casual meetups when you don’t need industrial-grade power.
Specs:
- Battery Life: 10,400mAh – about 1.5 full phone charges
- Device Limit: 2
- Display: LED indicator lights
- Ports: USB-C input/output, USB-A
- Weight: ~220g
What to know:
It doesn’t support fast charging beyond basic 5V/2A levels, so don’t expect your phone to charge rapidly. But for a basic top-up on the go, it’s reliable and non-intrusive.
This is the workhorse in your list. If you’re working remotely from Starbucks, meeting clients across the island, or travelling to JB or KL, this powerbank is your portable charging station. It can charge a MacBook Pro, iPad Pro, and phone — all at the same time.
What sets it apart?
145W output. That’s serious charging power, almost like plugging into a wall socket. It also supports fast recharging of the bank itself, so you’re not waiting overnight to top it back up.
Specs:
- Battery Life: 25,000mAh – up to 5 phone charges
- Device Limit: 3
- Display: Digital percentage display
- Ports: 2x USB-C (one with 145W PD), 1x USB-A
- Weight: ~550g
What to know:
If your laptop supports USB-C PD charging (most modern MacBooks, Surface devices, Lenovo ThinkPads), this is gold. But if you’re just charging a phone, it’s probably overkill. Great investment if you’re a freelancer or remote worker.
From a trusted local brand, this is a great “daily driver” powerbank. It’s compact, decent speed, and has a solid warranty from Challenger — handy if something goes wrong.
What sets it apart?
You get USB-C PD output, which is still rare in cheaper brands. And because it’s local, you can walk into Challenger or Courts to get help if needed.
Specs:
- Battery Life: 10,000mAh – about 1.5–2 phone charges
- Device Limit: 2
- Display: LED battery status
- Ports: USB-C PD, USB-A
- Weight: ~200g
What to know:
Good entry-level option if you’re buying your first powerbank or just want something reliable to keep in your work bag. Doesn’t charge tablets or laptops efficiently — phones only.
This one’s basic but dependable — kind of like a Toyota Corolla of powerbanks. It doesn’t support the latest PD charging standards, but it’ll charge two phones slowly and steadily, and it lasts a long time.
What sets it apart?
You get large capacity for a budget price. Great for long train rides, road trips, or as a shared powerbank between friends or family.
Specs:
- Battery Life: 20,000mAh – about 3–4 phone charges
- Device Limit: 2
- Display: LED battery indicator
- Ports: Dual USB-A output, USB-C input only
- Weight: ~370g
What to know:
If your charging needs are basic — like topping up phones overnight or slow-charging two devices while you’re out — this gets the job done. Not recommended for fast charging or heavy multitasking.
This one's for folks who want something that looks good and charges well. The Airpow supports 20W PD, which is enough for fast-charging most phones, and the overall design feels modern — clean lines, minimal branding, and matte finishes.
What sets it apart?
You don’t often get this level of performance and build quality at this price. Great for office use, café setups, or just something that looks respectable on your work desk.
Specs:
- Battery Life: 20,000mAh – about 3–4 phone charges
- Device Limit: 3
- Display: LED battery status
- Ports: USB-C PD (20W), 2x USB-A
- Weight: ~420g
What to know:
20W is great for phones and tablets, but it’s not enough for laptops. Also, it charges the powerbank itself a bit slower than premium models — expect around 6–7 hours for a full charge. Still, for $70–$80, it’s hard to beat the value.
Frequently Asked Questions Answered by the ProductNation Team
Can I bring a powerbank on a plane?
Yes, you can — but got rules lah. Powerbanks must go in your hand-carry, not checked luggage. As long as it’s below 27,000mAh (100Wh), you’re good. That covers most powerbanks in this guide.
One more thing — some airlines don’t allow you to use your powerbank during the flight. So even if you bring it on board, you might have to keep it off and stowed.
If you’re heading to JB by bus or train, no issues at all. Just make sure your powerbank's fully charged — the ones with LED displays help a lot.
How many times can it charge my phone?
Depends on your phone’s battery size and the powerbank capacity. Here’s a rough guide:
- 10,000mAh: Can charge most phones 1.5 to 2 times
- 20,000mAh: About 3 to 4 full charges
- 25,000mAh: Around 5 charges, give or take
Of course, you’ll lose a bit of power to heat and conversion, so don’t expect it to be 100% efficient.
Can I use a power bank to charge my laptop or iPad?
Yes — but only if your power bank has enough output power.
- iPads and tablets? You’ll want at least 30W output.
- MacBooks and laptops? Go for 65W and above, with USB-C PD (Power Delivery).
If your power bank only has USB-A or is under 18W, then sorry — it’s probably not going to cut it for laptops.
Why do power banks catch fire sometimes? Is it safe to leave it charging overnight?
Power banks don’t just randomly catch fire — usually, it’s from overheating, bad cables, cheap components, or people using damaged ones.
To be safe:
- Don’t charge it on your bed or under a pillow (we’ve all done it — just don’t)
- Use a decent-quality cable
- Stop using it if it looks bloated or smells weird
As for overnight charging, modern power banks usually have protection chips, so it’s technically safe. But if you want to play it safe, unplug it before you sleep, lor. Especially if you’re charging on wooden surfaces or soft bedding.
How do I dispose of an old or spoiled power bank in Singapore?
Don’t just throw it in the bin. Power banks have lithium batteries — those things can catch fire if crushed.
Here’s the easy way:
- Tape the ends to cover the ports
- Put it in a small plastic or ziplock bag
- Drop it off at an e-waste bin — you can find them at malls, community centres, some MRT stations, or even electronics shops
It’s free, takes 2 minutes, and keeps toxic stuff out of the landfill. Small thing, big difference.
Conclusion
At the end of the day, the best powerbank is the one that fits your lifestyle, not just the specs on paper. If you’re only out for a few hours, something light and compact is probably all you need. But if you’re out from morning till late, or juggling multiple devices, go for something with more capacity and faster charging.
And if you work remotely or need to power a laptop while moving between places, a high-output model will save you a lot of hassle, even if it’s heavier.
Don’t just pick the biggest or cheapest one. Think about how you use your devices day to day, and choose a powerbank that quietly supports that without getting in the way. That’s the real win.
