A unmarried AA battery. That’s all that’s wanted to power principally essentially the most common phone dubbed SpareOne Plus. As chances are you can perhaps perhaps be in a task to reveal through the name, this one is meant to be a backup phone most effective to be veteran in case of emergency (it changed into once to start with designed for first responders).
Its best purpose is that it could neatly perhaps perhaps sit on a shelf for 15 years and be able when you want it. Trendy phones with their lithium batteries can’t fit such patience – the self discharge payment can be as prime as 2% per thirty days, which way lithium batteries lose payment even if the device is totally powered down.
And in addition they are, evidently, very advanced to switch out. Now now not so on the SpareOne, which lets you pop in a modern battery with out factor. You probably have already got an AA battery or two on the backside of a drawer, speedy-witted?
Here’s a very powerful as a result of it’s slightly common for a difficult typhoon or flooding to knock out the power grid. Speaking of, the phone’s packaging served double duty – it’s a water-resistant pouch, so that chances are you can perhaps perhaps be in a task to fish it out of a flooded cellar and the phone will peaceful paintings.
This changed into once a very common phone. It had 2G connectivity most effective (two bands), which is a situation in america – AT&T already close down its 2G community, T-Mobile will observe wander smartly with in the next few months and proper here is a GSM phone, so it could neatly perhaps perhaps’t sign up for to legacy CDMA community. The SpareOne first got here out less than 15 years in the past, through the way. Abilities ages sooner than maximum issues, even if its meant to ultimate over a decade.
It is perhaps you can perhaps perhaps pre-program the phone with 9 favorite contacts, or use the keypad to dial any quantity. There’s no divulge (merely a couple of status LEDs), so a advise would be in contact the digit you typed. Also, the emergency button (the plus) sends out your house to make a answer contacts as effectively since the government too – common as a result of it’s, the phone is helping Enhanced 9-1-1 (the usage of triangulation).
That unmarried AA battery is authentic for as much as 10 hours of communicate time. And when you wanted to provide your include SIM card for making calls to friends and circle of relatives, calling 9-1-1 doesn’t require a SIM. If you wanted to, chances are you can perhaps perhaps neatly purchase out the SIM card from your (probably useless) smartphone and dad it into the SpareOne. There changed into once a SIM ejector software and a microSIM adapter stashed all of the blueprint via the phone to make it more straightforward to with that activity.

There could be moreover a light LED torch on prime, that can end up to be to hand in case the power is out. There’s no FM radio receiver, on the other hand, which might perhaps perhaps perhaps neatly were excellent so that chances are you can perhaps perhaps neatly listen to emergency bulletins.
The SpareOne Plus wasn’t a actually successful product as it payment $60 when it to start with introduced. On the opposite hand, this present day chances are you can perhaps perhaps be in a task to fetch one for under $10 on eBay. But believe that 2G networks round the realm are shutting down, they’ll definitely be lengthy long gone quicker than the battery expires.
A few years later SpareOne got here out with a 3G fashion of the phone (moreover, the 2G modem changed into once upgraded to quad-band). That in reality extends the life of the device, regardless that some 3G networks have already close down, so slightly quickly this phone will face the related issues as its 2G sibling.
One different improve is that this model featured a correct GPS receiver, so that it could neatly perhaps perhaps calculate your house extra as it should be than cellular tower triangulation. Between the GPS and 3G connectivity, this SpareOne phone wanted two AA batteries.
These weren’t principally essentially the most simple phones to be powered through shaped AA or AAA batteries. If fact be informed, within the early days of cellular phones something love this changed into once slightly common. But at the moment we’re drawn to the extra provide units.
Esteem this burly factor from Sanyo. It changed into once powered through a unmarried AA battery, a chargeable NiMH battery this time, which changed into once authentic considerable for 10 days of standby or 5 hours of communicate time (this changed into once once more a 2G-most environment friendly phone).
Having a believe at it, we expect this changed into all in every single place once more of an ability to advertise Sanyo’s Eneloop batteries than a correct attempt to advertise phones. It changed into once a exhibit of the low self discharge payment enabled through the Eneloop skills.
The Olive FrvrOn (“eternally on”) changed into once a extra earnest attempt to advertise phones. And it changed into once a seriously higher phone too. Now now not wonderful or the recreational, however it had a 1.5” colour divulge (CSTN) with 128 x 128 px answer. And it did have an FM radio.
There changed into once a 600mAh Li-Ion rechargeable battery built in, on the other hand the phone would possibly perhaps perhaps moreover be powered through a unmarried AAA battery. The FrvrOn changed into once introduced in India help in 2010 and had a payment INR 1,700 on the time ($37 or so).
AA and AAA batteries aside, lots of unfamiliar techniques were proposed to power a phone. Some of them practical, others now not so mighty. As a demonstration, we already appeared help on the Samsung Blue Earth, which had a sun panel on its help. As did the Puma Phone.

You needed to be very affected particular person with those to achieve even a shrimp whilst of communicate time. That’s peaceful higher than the Ulysse Nardin Chairman, which veteran a rotating weight to trickle-charge the battery from the power of your movement (the similar to computerized watches, which is Ulysse Nardin’s main trade).
The Ulysse Nardin Chairman changed into once as sumptuous as it changed into once impractical
A extra affordable – if merely as impractical – resolution changed into once to make use of wind power with an accessory love the iFan. Alas, this changed into once a trust that by no means made it to consumers.
Wind-powered iPhones have been on the table at one stage, the usage of the iFan accent
There changed into once moreover the Pan Charger, which veteran a Peltier factor to turn warmth into electrical energy. Did anyone articulate coal powered cellular phones?
On the opposite hand, our “favorite” way ever proposed changed into once dreamed up through South Korea’s Sungkyunkwan College – it changed into once environment up a skills that quiet power from your advise to power the phone.
Granted, the prototype required 100 dB of sound – that’s as loud as a jet commencing or the usage of a jackhammer – so that chances are you can perhaps perhaps have wanted to yowl relatively quite a bit to invent a reputation. We suppose we’ll observe texting, thank you.
