Best Power Bank 2026: Top 5 Compared

The best power bank of 2026 is the Anker Powerbank 20,000 mAh with 30W Power Delivery: it fast-charges both an iPhone and a lightweight laptop, offers 2× USB-C plus 1× USB-A, and Anker has spent years building a reputation for reliable batteries and long service life. If all you need is a backup for your phone, the Cazy Mini 10,000 mAh (compact, festival-friendly) has you covered; for long working days and tablets, the Basey 20,000 mAh with its included 60W charging cable is a strong all-round package, and if you want to keep your entire setup topped up, go for the Nedis 65W with 32,000 mAh. In this guide we compare five power banks on capacity, charging speed and ports — with prices updated daily.

You choose a power bank based on capacity (mAh, which determines how many times you can recharge), charging power (watts, which determines how fast you can charge and whether you can top up a laptop) and ports (USB-C is the standard for 2026; USB-A is handy if you want to keep using older cables). Every pick below has a verified live price on productvraag.nl.

Anker Powerbank 20,000 mAh 30W — best power bank of 2026 (€25-€35)

The Anker Powerbank 20,000 mAh 30W is the all-rounder most people are looking for: enough capacity for 4 to 5 full phone charges, and enough wattage to top up lightweight laptops (MacBook Air, ultrabooks) via USB-C Power Delivery. This version has 2× USB-C and 1× USB-A, so you can connect several devices at once, and Anker documents its safety features (temperature and voltage protection) extensively in the product information.

As a brand, Anker is the de facto benchmark in the power bank category: its batteries consistently perform well in independent real-world tests, and the company typically offers longer warranty periods than no-name rivals.

Best for: anyone who wants one dependable power bank for their phone and the occasional lightweight laptop, and values a proper brand warranty.

Basey Powerbank 20,000 mAh with 60W charging cable — best bundle deal (€21-€28)

The Basey delivers the same capacity as our top pick (20,000 mAh, roughly 4-5 phone charges) and likewise offers USB-C and USB-A, 22.5W fast charging and an LED display showing the remaining capacity. What makes this bundle stand out: a 1.5 m 60W charging cable comes included, so you can also recharge the power bank itself faster through a suitable adapter.

The 22.5W output is fast enough for most smartphones (iPhone 15/16, Samsung Galaxy S series), but less powerful than the Anker's 30W if you want to top up a laptop. In return, you get the cable for free.

Best for: anyone who wants a complete package for life on the go (power bank + charging cable) and mainly charges phones.

Cazy Mini Powerbank 10,000 mAh — best compact option (€13-€17)

The Cazy Mini proves that you don't need a kilo of battery for a day out: 10,000 mAh is good for roughly 2 full phone charges, with 22.5W fast charging over USB-C. The name says it all: this is a decidedly small power bank, optimised for festivals and day trips where weight and bulk matter.

Both ports (USB-C and USB-A) are on board, and at 22.5W a modern smartphone gets most of the way back to full in around 30 minutes. For tablets and laptops this class is less suitable — the number of charges simply becomes too limited.

Best for: short trips and festivals; anyone after a backup that doesn't eat up space in their bag.

Nedis 65W Powerbank 32,000 mAh — best for laptops and multiple devices (€60-€82)

With 32,000 mAh and 65W of USB-C output, the Nedis is our pick for anyone who wants to properly recharge a laptop: 65W is enough for most MacBook Pro 13, Dell XPS 13 and comparable business laptops. At this capacity you get around 6-7 phone charges, or 1 laptop charge plus a few phone charges on top.

Do note: at 32,000 mAh (roughly 118 Wh) this power bank sits above the standard 100 Wh aviation limit, which puts it in the 100-160 Wh band — most airlines will carry it in hand luggage, but only with prior approval, so check before you fly. It is also bigger and heavier than the 20,000 mAh class — expect around half a kilo in your bag. Port-wise you get one USB-A port at 18W and one USB-C port that delivers the full output.

Best for: professionals who want to keep working on a laptop on the move, without hunting for a wall socket.

Besjaar Powerbank 10,000 mAh — best budget pick (€16-€22)

The Besjaar offers 10,000 mAh of capacity with 22.5W fast charging over USB-C, an LED indicator for the remaining charge, and both a USB-A and a USB-C port. For anyone buying their first power bank, or simply wanting a spare for the office, the car or the emergency kit, this is the cheapest credible option in this comparison.

Don't expect premium build quality or extras such as wireless charging — this is purely functional hardware.

Best for: a spare power bank at home, in the car or as a gift; anyone who doesn't want to spend €30 on an emergency battery.

How many mAh do you need?

A modern smartphone has an internal battery of roughly 4,000 to 5,000 mAh. As a rule of thumb:

• 5,000 mAh — one emergency charge for your phone; lives at the bottom of your bag, just in case.
• 10,000 mAh — roughly 2 full phone charges; compact, ideal for a day out.
• 20,000 mAh — 4 to 5 phone charges; enough for a weekend away from a socket, or for topping up lightweight laptops.
• 30,000 mAh and up — several days off the grid, laptop charging, or one power bank that serves the whole family. Big and heavy.

Rough rule of thumb: power bank capacity ÷ 1.5 ≈ usable mAh that actually ends up in your phone. You always lose 20-30% to heat and to the conversion between the battery cells (3.7V) and the output (5V or higher).

USB Power Delivery and wattage: how fast does it charge?

With power banks, the wattage of the USB-C port determines how fast you can charge — and whether you can top up a laptop:

• 18-22.5W — fast charging for smartphones (Samsung, iPhone). An iPhone goes from 0 to 50% in around 30 minutes.
• 30W — the ceiling for smartphones; enough for ultrabooks (MacBook Air, Dell XPS 13) to trickle-charge while in use.
• 65W and up — charges most business laptops just like their regular charger would. USB-C Power Delivery is the standard.
• 100W — power users, workstations, gaming laptops.

USB Power Delivery (USB PD) is the open standard that Apple, Samsung, Dell and others adhere to. As long as both the power bank and your device support USB PD, they automatically negotiate the highest possible wattage.

Can you take a power bank on a plane in your hand luggage?

Yes, provided it stays under 100 Wh (watt-hours), which works out to roughly 27,000 mAh with 3.7V cells. Four of the five power banks in this comparison fall within that limit; the 32,000 mAh Nedis (roughly 118 Wh) sits just above it and requires prior approval from your airline. Power banks must always travel in your hand luggage — never in checked baggage. For 100-160 Wh (large 40,000+ mAh models) you need the airline's permission in advance. Always check your own airline's rules before departure, as the limits can differ from one carrier to another.

USB-C or USB-A: which ports should you look for?

USB-C is the standard in 2026: all new smartphones (apart from older iPhones up to and including the 14), laptops, tablets and many accessories charge and communicate over USB-C. Choose a power bank with at least one USB-C port that handles both input and output.

USB-A remains useful if you want to keep using older cables (the classic iPhone Lightning cable, many headsets, e-readers, in-car power banks). All five of our picks combine both standards.

Frequently asked questions about power banks

Can I take a power bank on a plane?

Yes, in your hand luggage — not in checked baggage. Power banks up to 100 Wh (roughly 27,000 mAh) are allowed without approval; 100-160 Wh requires the airline's permission. Always check your airline's current rules.

How many times can I charge my phone with a 20,000 mAh power bank?

Roughly 4 to 5 times for a modern smartphone (4,000-5,000 mAh internal battery). Factor in 20-30% conversion loss: of the 20,000 mAh on the label, around 13,000-14,000 usable mAh actually remains.

What does Power Delivery (PD) mean?

USB Power Delivery is the open standard that allows smartphones, tablets and laptops to automatically negotiate the highest supported wattage — up to 100W (and up to 240W with PD 3.1). Without PD, charging speed usually gets stuck at 5W or 10W, even if the power bank can deliver more.

How long does a power bank last?

Reliable brands (Anker, Nedis) typically quote 500 to 800 full charge cycles before capacity noticeably declines. With normal use (a full cycle 2-3 times a week) that works out to roughly 4 to 6 years. Cheap no-name batteries sometimes lose noticeable capacity after just 1-2 years.
