StromPi, The Uninterruptible Power Supply for Raspberry Pi

It seems evident that the Raspberry Pi and its clones have filled an enormous hidden need. The digital performance of such micro-computers is exceptional as long as they are used without any special dependence on power requirements, that is to say near an electrical outlet with power! Faced with the vagaries of the analog world, these tiny cards that fit in the palm of your hand are not as beefy as that. Their dependence on their power supply has highlighted a new need, well identified by the manufacturer JOY-iT. StromPi, their adaptable uninterruptible power supply (UPS) mini card lets you use a Raspberry Pi under conditions of unusual or unstable power, without taking up much space, and without risk of data loss in case of a power cut.

Two working modes are offered:

  • UPS (uninterruptible power supply), i.e. no break power
  • WIDE, which allows an extended range of input voltage

With the following characteristics

  • wide range of DC input voltage, from 6 V to 61 V in WIDE mode
  • 5 V power input on microUSB connector
  • maximum USB output current of 3 A
  • very low standby current
    • (in UPS mode): 20 to 80 μA (that’s between 175 mAh and 700 mAh per year)
    • (in WIDE mode): 3 to 7 mA

In the case of loss of power, the StromPi backup power card not only starts the process of data backup before the Pi is switched off, but it can also guarantee startup once the power is restored (this function may be deactivated with a jumper strap).

When that happens, you can even select to be informed by an email sent by the Raspberry Pi program (which you can download).

ChargEST, A Travel Adapter To Charge Your Devices

When you travel, it’s a bit frustrating to fill your luggage with lots of chargers, cables, and adapters to fit your charging needs. In addition to the space it takes which makes it harder to bring every kind of charger you may need.

ChargEST is designed to become your charging companion anywhere in the world you might be, so you can power up all your devices with a single accessory. It is compatible with USA, UK, Europe, Australia and 150 other outlet and plug standards, that charges cable-less up to two mobile devices with its fast-charging integrated pins and any other devices with the three USB ports.

The ChargEST is a small 8x8x4 cm portable device that fits in your pocket. It is built using high-quality materials and has three fast-charging USB ports, GoGreen on/off button, two height adjustable MicroUSB pins, and USB-C and Lightning plug extensions. You can charge up to six devices at the same time with 6.3A total charging power.

Safety comes as a top priority for ChargEST. Equipped with child-proof design and protection for overheating, short-circuit, voltage variation, and overcharging, you can be assured of having a safe charging experience every single time.

In addition to the ChargEST adapter, there are another two versions: ChargEST Bank, and ChargEST Double. The Bank provides you with extra 6300mA battery for your ChargEST to stay charged wherever you are on the go. It can fully-charge your iPhone or Android smartphone up to 3 times and also has an additional USB outlet to charge any other device.

ChargEST Double is the same of the original ChargEST but with an extra socket to connect other devices.

Six days left for the Indiegogo campaign with a goal of $20,000. However, they raised around $200k till now.
