Smartphone Waves and Cancer: The Answer is No, But Caution Remains
Table of Contents
The answer is no. After peeling 232 scientific studies, ANSES is clear: the waves from your smartphone do not cause cancer. though, the health agency continues to advocate “caution”.
We will try to close this case once and for all (or not). The National Health Security Agency (ANSES) just published a massive study this Wednesday morning. The subject? this smartphone that hangs around in your pocket all day and emits radio frequencies.
The verdict fell after the analysis of 232 studies published between 2013 and 2024: the agency does not find no causal link between exposure to waves and the appearance of cancer. It’s writen in black and white.
If you thought that this was going to signal the end of playtime and anxieties around 5G antennas, you are wrong. ANSES,faithful to its ancient line of conduct,maintains its recommendations of “caution” and “reasoned use”.

The science is clear
Let’s look at the facts. ANSES did not work lightly. She compiled thousands of data, separating epidemiology (the observation of human populations) from toxicology (lab tests on animals).

The Ultimate Portable Power Station Guide
One battery to charge them all.
Portable power stations are rapidly becoming essential for outdoor adventures,emergency preparedness,and even simplifying everyday life. They offer a convenient, quiet, and emission-free alternative to traditional gas generators. but with so many options available, choosing the right one can feel overwhelming. This guide breaks down everything you need to know about portable power stations, from understanding capacity and features to selecting the best model for your needs.
What is a Portable Power Station?
A portable power station is essentially a large-capacity battery pack with multiple output ports. Think of it as a wall outlet you can take anywhere. They’re typically recharged from a wall outlet, solar panels, or even your car’s 12V outlet. Unlike gas generators,they produce no fumes,require no fuel,and operate silently. They’re ideal for camping, tailgating, RV trips, or providing backup power during outages.
Key Features to Consider
- Capacity (Watt-hours): This determines how long you can power your devices. Higher watt-hours mean longer runtimes. Consider what you plan to power and for how long. A small power station (200-500Wh) is good for phones and laptops, while a larger one (1000Wh+) can run appliances like refrigerators or power tools.
- Output Ports: Look for a variety of ports,including AC outlets (for standard appliances),USB-A and USB-C ports (for phones,tablets,and laptops),and 12V DC ports (for car accessories).
- Inverter quality: The inverter converts DC power from the battery to AC power. A pure sine wave inverter is crucial for sensitive electronics like laptops and medical devices. Modified sine wave inverters are cheaper but can damage some electronics.
- Charging Options: Most power stations charge from a wall outlet. Solar charging is a popular option for off-grid use. Some also offer car charging.
- Weight and Portability: consider how often you’ll need to move the power station. Larger capacity models are heavier.
- Battery Type: Lithium-ion batteries are the most common due to their high energy density and long lifespan. LiFePO4 batteries offer even greater safety and longevity, but are typically more expensive.
How to Calculate Your Power Needs
Before you buy, determine how much power you’ll need. Here’s how:
- List your devices: Make a list of everything you want to power.
- Find the wattage: Check the label on each device to find its wattage. If it only lists amps, multiply amps by volts (usually 120V in the US) to get wattage.
- Estimate runtime: Estimate how many hours you’ll use each device.
- Calculate total watt-hours: Multiply the wattage of each device by its runtime. Add up the watt-hours for all devices to get your total power needs.
- Add a buffer: It’s always an excellent idea to add a 20-30% buffer to account for inefficiencies and unexpected power draws.
