Power Banks
Last updated: June 13, 2026
Stop carrying around dead weight. In June 2026, if your power bank cannot charge a laptop or survive a weekend in the Peak District, it is a paperweight. I have tested the lot, from pocket-sized lifesavers to solar monsters that could power a small flat in Hackney. Here is the brutal truth on what is actually worth your hard-earned quid.

Ask the Community βHow to Choose a Power Bank Without Getting Ripped Off
Most people buy based on the biggest number on the box. That is a mistake. Here is what actually matters when you are standing in the shop.
Capacity vs. Portability
A 25,000mAh bank sounds great until you realise it weighs as much as a bag of flour. For a daily commute, 10,000mAh is the sweet spot. Only go bigger if you are a digital nomad or planning to disappear into the woods for a week.
Wattage and PD Standards
It is 2026; if it does not support Power Delivery (PD), leave it on the shelf. You want at least 20W for a mobile and 65W+ if you intend to keep your laptop alive during a meeting.
The Port Problem
USB-C is the king. Avoid anything that still relies on Micro-USB or Lightning for input unless you enjoy carrying five different cables like a 1990s IT technician.
Frequently Asked Questions
Can I take these on a plane?
Most airlines draw the line at 100Wh. The Anker 165W is usually fine, but that SOLIX solar beast will get you tackled by security before you reach the gate.
Why does my 10,000mAh bank only give me two charges?
Because physics doesn't care about marketing. Energy is lost as heat during the transfer. Expect about 60-70% actual efficiency from any bank.
