INIU 10000mAh Portable Charger Review
In their 2019 product line, INIU Technology brings us the BI-B1 10000mAh portable power bank, a reliable choice with an innovative twist. Read on to learn more about its unique characteristics and features.
Capacity & Charging speed
The INIU BI-B1 features two USB outputs with a maximum power output of 2.4A each, which enables charging your devices up to 1.4 times faster than with their factory charger. Even though it doesn’t support Quick Charge or Power Delivery protocols, that’s just shy of 1 hour and 36 minutes for an iPhone X or 1 hour and 10 minutes for a Samsung S9, both of which you could even charge at the same time with no noticeable increase in the charge time. Besides, it comes with a convenient and decorative display which makes it possible to see the remaining charge at a glance.
As for the power input, you can use your phone charger with the included Micro USB cable to bring it from empty to fully charged in around 5-8 hours depending on your charger’s amperage. One curious feature of the device is that its output is not controlled by pressing the power button, but instead by the power draw from the USB ports. The power bank checks twice a minute if there is a power consumption greater than 45mA in either USB port and supplies power depending on it.
Although the INUI BI-B1 can be daisy-chained between the charger and your phone, it won’t allow for current passthrough, that is, the current that is currently charging your phone does not come directly from the wall socket but from the battery. Although this might seem like a bad thing, it is actually beneficial if you live in an area where the electrical supply is not particularly trustworthy or you find yourself traveling abroad where the same might be true.
Your device stays protected by the advanced charging circuitry, prolonging its (and its battery’s) usable life. Lastly, there is a caveat for the new owners to this kind of device: While adequate for phones, e-readers, tablets, or even smaller USB-C powered notebook computers, the amperage provided by the power bank might prove excessive for USB devices with very small batteries, like hearing aids, smartwatches or Bluetooth headsets.
Look and feel
The INIU BI-B1 features a sturdy yet lightweight plastic construction and a black matte rubberized exterior, resistant to scratches and scuffs. The charge blue LED display, in the shape of a dog’s paw-print, is located at the front of the unit near the USB input and outputs. This novelty display indicates the current charge by lighting up more toes of the paw-print, making it an excellent conversation piece for when you’re around your tech-oriented acquaintances.
Lastly, the flashlight button’s construction is consistent with the long-duration microswitches of modern smartphones, with a clean action and just enough resistance to keep it from being accidentally set off. As a nice bonus, one that is often overlooked by manufacturers, the INUI BI-B1 includes a nylon protective pouch which does a decent job at protecting the power bank while being knocked around in the busy confines of the average purse or backpack.
INIU Technologies has not overlooked the industry trend to reduce the size and weight of batteries and power banks, so the BI-B1 sits comfortably in the semi-light weight category at 7.4 oz. Its 5.5 x 2.8-inch form factor makes it easily portable and its 0.5-inch thickness means you can easily slip it into your pocket even when in use. It also includes both a built-in LED torch, which can be turned on by pressing the corresponding button twice in quick succession, and a USB LED reading lamp which goes in one of the USB ports. Its low consumption means you can expect lighting times upwards of 12 hours.
Since the Li-Po battery is rated at 37Wh, well below the mandated 100Wh limit for lithium-ion batteries on commercial aviation, the power bank is completely allowed to be carried aboard any flights, as long as you have it in your carry-on bag, that is. The company states that the USB 2.0 to Micro USB cable they include with the power bank is only 30 cm (1 foot) long because people find it more portable, although if you’d like a longer cable it’s a good idea to get in touch with them via their business e-mail including your order number, after which they should reply within 24 hours. If you live in an area where power outages due to emergencies are frequent or if you’re into being always prepared, the INIU BI-B1 can keep a full charge for about two months, after which it will start to dissipate, so keep that in mind.
