Description

A large-sized rechargeable battery pack for your Raspberry Pi (or Arduino, or Propeller, or anything else that uses 5V!). This pack is intended for providing a lot of power to an GPS, cell phone, tablet, etc but we found it does a really good job of powering other miniature computers and micro-controllers. If you want something a little smaller, we have a 4400mAh power pack with one USB port that can provide up to 1A We tested it with an iPad mini, iPad 1 & 3 and iPhone 5 & 5s so we know it will charge those models.

Inside is a massive 10,000mAh lithium ion battery, a charging circuit (you charge it via the USB cable attached), and two boost converters that provide 5VDC, 1A and 2A each via a USB A port. (The markings indicate one is good for 1A and one is good for 2A) The 2A output is best for charging tablets or other really power-hungry devices. But either can be used for when you want to power a Beagle Bone or Raspberry Pi, wifi adapters, maybe even small displays. We hooked it up to a 2.5" NTSC display (powered from the Pi's 5V breakout lines), wireless keyboard/mouse and a small WiFi dongle and it hummed along just fine as a mini computing setup!

The charging circuit will draw 1A from a 5V supply (plug a microUSB connector into the pack and then to a computer or wall adapter). You can charge and power something at the same time but the output switches to the USB input when charging so the output voltage may fluctuate. Its not good as a 'UPS' power supply for an embedded linux board, although microcontrollers like Arduino may not care about the voltage drop as much. Also, there's ~80% efficiency loss on both ends so if you charge it at 1A and draw 1A at the same time, the battery pack will eventually go empty. However, if you're powering something thats 500mA or less, you can keep it topped up no problem.

Product review & video

hey everyone mr. Suja no here in today's video we're gonna see if we can power a Raspberry Pi 4 with a portable battery let's get started so if you haven't checked out the community tab on my YouTube page I recommend doing so sometimes I do post polls and try to get an idea of what kind of video you'd like to see next for example here I posted a poll about a week ago and I asked if you'd like to see something on the NeoGeo arcade stick Pro the terrible graphics mini or something else and on this poll lucky Ram left a very interesting comment can I use a power bank on the Raspberry Pi 4 I really like this question because the PI 4 draws a lot of power and comparison I can use a PI 3 with a power bank without issues I actually have two power banks that work very well with the PI 3 so in this video we will put them to the test with a PI 4 so the first battery that we will take a look at is
