The latest addition to the team, back in 2017, Yoni Marchal-Laporte is also one of its most active writers. A traffic manager by training, he handles audience acquisition and search optimization, but it is above all as a writer that he has made his mark: he authors a good share of the blog's in-depth features and comparisons. His dual profile, technical and editorial, makes him a writer apart, able to grasp both what a search engine is looking for and what a reader hesitating between two products expects.
His real strength is synthesis: taking a tangled subject (a new battery chemistry, a European regulation, a feud between brands) and drawing from it a clear, well-ordered, immediately useful answer. He is not an engineer, and makes no secret of it: he is a researcher at heart, cross-checks the data, hunts down false marketing promises and always puts himself in the buyer's shoes. It is his articles, such as "What are the advertised mAh really worth?" or "Anker vs Ugreen", that most concretely help visitors decide.
A young dad and keen cyclist, he devours the roads of Lozère at the weekend, a solar charger tucked into his jersey pocket. His colleagues tease him about his mania for archiving his comparison tables with obsessive rigor, but no one complains the day they need to dig up a three-year-old benchmark in thirty seconds.
One last detail, which he insists on pointing out himself and without the slightest embarrassment: he is the one who writes the profiles for the whole team, his own included. You have therefore just read a portrait written by its own subject, which no doubt explains the "as talented as he is modest" that still, mysteriously, lingers in his original bio.
On one side, Anker, the pioneer turned benchmark. On the other, Ugreen, the challenger shaking up the market with fast charging and aggressive pricing. We tested 19 power banks from the two brands: here is what the measurements really say, backed by the figures and by model-by-model head-to-heads.

The US CPSC and Goal Zero have recalled about 46,200 YETI 3000X power stations after several overheating reports. A free firmware fix is available: here's how to check your unit and install it before using it again.

This summer’s alarming headlines are aiming at the wrong target: your power bank is not banned from aircraft. What changed is that, since 27 March 2026, an ICAO rule forbids using it or recharging it in flight, and caps you at two per passenger.

From 18 August 2026, every battery placed on the EU market must carry a standardised label: chemistry, capacity, weight, place and date of manufacture, critical raw materials. One short line of regulation that will change a great deal when you stand in front of two power banks, or two packs of AA cells.

20,000 mAh on the label, but barely two smartphone charges: normal, or a scam? The capacity advertised on a power bank and the energy you actually get back are two different things. This feature explains why, how to read the real figures, and above all how to spot inflated capacities.

It is the advice everyone repeats: never charge your battery to 100 %, stay between 20 and 80 %. Sensible reflex or urban legend that complicates your life for nothing? We dug into the chemistry behind the rule to sort what really matters from what is just overkill.

It is billed as the battery of the future: more range, lightning-fast charging and, above all, more safety. The solid-state battery has been a dream for years, but is it finally delivering in 2026? We sort the marketing announcements from the industrial reality, without the jargon.

From 18 February 2027, European regulation EU 2023/1542 requires that batteries in portable devices be easily replaceable by the user, an EU-only rule with no US equivalent yet. Here is what it actually requires, and what it signals for anyone buying power banks, smartphones, cordless vacuums, and portable power stations.

Cheaper, more resistant to cold, made from a material found in abundance: the sodium-ion battery is generating a lot of buzz. A revolution on the way, or simply a complement to lithium? We take stock of a technology that is only just leaving the labs.
