This Battery Charger Shows Which AAs Are Dead on an E-Ink Display

Posted on by

The drawer full of half-used AA and AAA batteries, some new, some dead, some leaking, is familiar. The last-minute scramble for batteries when a remote dies usually means digging through the pile, testing them one by one, and feeling uneasy about throwing spent alkalines into the trash. The problem is not just waste, it is the lack of a clear system for how we power small devices scattered around a home.

Linogy is a rechargeable battery ecosystem built around 1.5 V Li-ion AA and AAA cells plus an all-in-one smart station. The station lives on a desk or shelf, acting as a battery tester, fast charger, and organizer case that holds up to 40 cells. The goal is to replace the random drawer with a single, visible place where all your batteries live and get managed.

Designer: Linogy

Disposable alkalines are convenient but add up to billions of cells tossed each year, along with tens of thousands of tons of waste and CO₂. Ni-MH rechargeables solve part of that but bring their own quirks: 1.2V output that some devices dislike, high self-discharge, lower energy density, and slow charging that makes topping them up feel like a chore you keep postponing.

Linogy’s cells pack around 3,600mWh and deliver stable 1.5V, closer to what devices expect from alkalines, so performance and battery indicators behave more predictably. The cells are rated for up to 1,200 cycles, meaning one rechargeable can stand in for roughly 1,200 disposables over its life, and built-in protection layers handle overcharge, short circuit, and drop impacts without leaks or smoke.

Dropping a mix of AA and AAA cells into the station, it automatically detects type, health, and charge level. The e-ink display shows which batteries are full, which are charging, and which are ready to retire, without bright LEDs or guesswork. A full charge takes around three hours, and once topped up, the station stops charging and simply holds the cells until something needs power.

The station is compatible with Linogy’s Li-ion cells, Ni-MH, and Ni-Cd AA and AAA batteries. You do not have to throw out existing rechargeables; the same box can test and charge them while you gradually swap in higher-capacity 1.5V cells. Over time, the random mix becomes a more coherent set of batteries you actually trust instead of avoiding.

A simple change in how you handle AA and AAA power can reduce waste and friction. One Linogy cell replacing up to 1,200 alkalines, recyclable packaging, and a charger that looks like a small appliance rather than a tangle of cables all add up. It turns the humble battery from something you forget about until it fails into a part of the home that is designed, visible, and surprisingly satisfying to keep in order.

Anker SOLIX E10 Brings Hybrid Whole-Home Backup to the Modern House

Posted on by

Modern homes depend on electricity for everything, from fridges and routers to medical devices and central A/C. Storms, rolling blackouts, and grid hiccups trigger a familiar scramble for flashlights and ice bags. Food spoils, devices die, and working from home becomes impossible. Most backup options either feel like camping gear with a couple of outlets or like a renovation project with permits and opaque pricing.

Anker SOLIX E10 is a smart hybrid whole-home backup system that blends batteries, green solar power, and a smart generator into one coordinated setup. It is designed to keep an entire house running, not just a few circuits, and is rated for whole-home backup with a 200-amp connection when paired with its Power Dock, matching a typical US main panel.

Designer: Anker

On a normal day, the SOLIX E10 quietly charges from solar and the grid, storing energy in modular 6 kWh battery packs that can scale to around 90 kWh with multiple stacks. When the power drops, the system steps in, deciding when to draw from batteries, when to add fuel through a DC link to its tri-fuel smart generator, and when to resume solar charging once the storm clears.

With the Power Dock or Smart Inlet Box, the SOLIX E10 can back up every circuit in a typical house, so you are not choosing between the fridge and the router. It is engineered to start and run a full-size 5-ton central A/C by handling the high inrush current that usually trips smaller systems, which matters when a summer outage hits during a heatwave.

When the grid fails, the lights stay on without flickering, the Wi-Fi does not reboot, and the A/C keeps humming. The system switches over in under 20 milliseconds, fast enough that most electronics never even notice. The feeling is less about the exact speed and more about the house simply not going dark anymore, even when the neighborhood does and trees are still down.

The SOLIX E10 can watch the weather and charge itself ahead of a predicted storm through its Storm Guard feature, so you are not caught with half-full batteries when the first tree hits a line. The modular packs give enough headroom for multi-day outages, while the forecasting takes backup power from a reactive scramble to a quiet ritual where the system prepares itself before you think to check.

The optional smart generator stretches backup power through long outages without running nonstop. Instead of charging through AC conversion, it feeds the batteries directly over DC, which Anker claims is up to five times more fuel-efficient than a traditional setup. It runs when needed, rests at night, and feels more like part of a system than a last-resort accessory.

The SOLIX E10 is not only for rare blackouts. On normal days, it can store cheap off-peak energy or excess solar and run the house when rates spike, trimming bills. Each unit accepts up to about 9 kW of solar input, so a rooftop array keeps the batteries topped up, and the system prioritizes important circuits to keep essentials alive longer during outages.

The hardware is a family of clean, stackable modules, with batteries that can be wall-mounted or floor-standing as the setup grows. The core units use an all-metal NEMA 4 enclosure and are certified to UL 9540 and UL 9540A, signaling they are built to live outdoors, handle bad weather, and meet the toughest residential safety standards.

Power anxiety is real, the feeling that one bad storm could wipe out food, work, and comfort for days. An outage where the house stays lit, the air stays cool, and the fridge keeps humming while the street outside goes dark is the payoff Anker SOLIX E10 is built around, making blackouts feel like minor blips instead of household emergencies.

This DIY Wooden Battery Charger Brings Dead AAs Back to Life

Posted on by

Most homes accumulate a drawer full of dead AA and AAA batteries, and the uneasy feeling of tossing heavy little cylinders into recycling or the trash. Alkaline cells are marketed as single-use, even though the chemistry can often be coaxed back to life with the right kind of intervention. RegenBox 1 is a small, hands-on challenge to that throwaway logic, turning battery regeneration into a bench-top ritual that requires patience, measurement, and a soldering iron.

RegenBox 1 is a kit that arrives as a flat collection of components, a printed circuit board, electronic parts, and laser-cut wooden panels. Once assembled, it becomes a USB-powered regenerator for AA and AAA alkaline batteries, designed for electronics hobbyists rather than casual users. The wooden case and visible PCB make it feel more like a lab instrument or workshop project than a sealed plastic charger, and building it yourself is half the point.

Designer: Regenbox

Assembly requires a soldering iron and solder, a voltmeter, flat-nose pliers, wire cutters, and a small screwdriver, plus some electronics confidence. The kit supplies the PCB, resistors, diodes, LEDs, IC, battery holders, USB cable, and the wooden enclosure. You are not just buying a gadget, you are learning how it works as you put it together, turning the components into a functional regenerator that can sit on your desk or workbench for years.

Using it starts with testing each alkaline cell with a voltmeter. Below 0.9 V goes to recycling, 0.9 V to 1.35 V is a candidate for regeneration, and 1.35 V to 1.5 V is already reusable. Once cells are slotted in and the USB 5 V input is connected, the circuit feeds very low current for 8 to 24 hours, slowly reversing part of the discharge without stressing the casing or causing leaks.

The boundaries are strict, alkaline only, no lithium, no damaged or leaking cells, correct polarity, and room-temperature use. The red and orange LEDs indicate current flow and help with diagnostics, but the real discipline is in measuring voltages before and after, and respecting the chemistry. It is not a fast charger; it is a patient tool that trades speed for safety and extended second lives.

Getting one or more extra cycles out of batteries that would otherwise be discarded adds up across a household or community. The open, repairable design invites modification and learning, turning energy use into something you can see and tweak. RegenBox 1 becomes a quiet protest against sealed, opaque devices, and a small workshop ally for anyone trying to reduce waste while gaining control over the objects they depend on.

RegenBox 1 changes the way you look at dead alkalines. Instead of being the end of the story, they become candidates for triage, measurement, and careful regeneration. The wooden box on the bench is a reminder that design can intervene not just at the point of purchase, but at the moment we usually give up on an object, asking whether it really needs to be thrown away yet or if a slow, gentle charge might bring it back for another round.

Duracell Portable Power Stations are like gigantic alkaline batteries

Posted on by

We’ve seen our fair share of portable power stations, and most of them roughly share the same designs. They come in rectangular box shapes and bear rugged materials, which makes it easier to transport them from place to place if needed. There isn’t any rule that says they have to be made that way, though, especially if you’re willing to skimp a little on the battery capacity to add some style and flourish. For example, Duracell, a name long associated with batteries, has had the rather amusing idea to pay homage to its most popular product line, resulting in portable power stations, or extra large power banks, that look like overgrown D-size batteries, with a few tricks up their sleeves that add some flavor to a normally boring piece of tech.

Designer: Duracell

There was a time when consumer electronics revolved around these cylindrical batteries that had to be thrown away once they lost their charges forever. We’ve thankfully mostly moved on from these wasteful energy sources, replacing them with rechargeable and reusable variants, but there’s still a certain fondness attached to the image of these old alkaline batteries that have become icons of their kind, just like floppy disks. Riding on the nostalgia trend these days, Duracell had the clever idea to put that iconic design on a portable power station, almost like a tongue-in-cheek joke on these extra-large batteries.

The Duracell M250 and M150 both look like giant D batteries, complete with a black and bronze color scheme and a smaller disc shape on top that designates the positive end of the cylinder. They’re rather small compared to most portable power stations but also considerably larger than even the largest power bank. The size differences are quite understandable considering these two only have 60,000mAh and 25,000mAh battery capacities for the M250 and M150, respectively, though those are enough to charge most electronic devices, including a laptop via the 100W USB-C port. The larger Duracell M250 even has a 100W AC port for other use cases.

The portable power stations have more than just looks, though. That protruding disc at the top actually functions as a MagSafe-compatible 15W wireless charger, and you can lift that top lid to tilt an iPhone or iPad to the desired angle so you can watch your screen even while charging. Tilting that cover also reveals a small storage compartment for cables and chargers, things you’d want to keep near the power station. To charge the power station itself, you’d have to put it on the included dock, an elegant solution that unfortunately means having to carry a separate part with you on your trips.

Admittedly, this traditional battery form is not the most space-efficient shape for traveling, putting the “portable” part of its name into question. Still, there’s no argument that it’s an interesting design for a portable power station, putting an almost poetic spin on the product category. It will definitely be an eye-catching presence in coffee shops or even on planes, though interest could turn into derision when you start fumbling to put the large can in your bag or luggage.
