    In this episode of HACKED! I will show you how I modified a common powerbank in order to cut down its ridiculously long charging time. Along the way I will talk about the powerbank circuit and why the battery pack of my powerbank is a bit special.

    Do you plan to explain a bit how to get 9/12 V output from powerbank which already supports it in some of your next videos? For Example, my Xiaomi powerbank is capable of 12 V @ 1.5 A output. From what I have read, a device needs to "ask" for the high voltage ("tell" the power bank it is the fast chargeable device). The question is, how to implement it. I found "CHY100
    ChiPhy™" IC for example. It would be very interesting to go more deeply to It. I imagine e. g. powering stepper motor with my powerbank. Thank you for your great content!

    Meh, just add some dc5.5 jack and get a 8.4v 3A(maybe 4A) charger. Would be faster and more convenient(since everything comes with a dc5.5 jack).

    If you have a hobby charger, this can also be accomplished by leaving everything attached and adding a JST-XH 3 pin port and XT60 connector. I trust my iCharger 1010b+ over almost any protection board sold so that is unnecessary for my setup.

    It would also have been awesome to use a fast charge spoof plug and a buck converter with cc/cv and a balancing BMS to fast charge it via USB.

    I hate when manufacturers list false capacities by adding up the capacity of all batteries. 72.36 watt hours, each cell is rated at a nominal voltage of 3.7 and the pack is in a 2s3p config. that means that 72.36/ 7.2 volts (voltage of the pack) equals 10.05 Amps or 10,050 mAh @ 7.2 volts instead of listing it as 20,100 @ 3.7 to make the capacity appear larger for those who don't know. 10,050 / 3 means that each cell has a capacity of 3,350 @ 3.7 volts. Those are usually rated at 3,400 though so I wonder what's going on. Watt hours is it only way to calculate the honest amount of energy in the battery pack.

    Nice! I did the same with a powerbank circuit made for 1S batteries, and put cheap 4x 5Ah 1S LiPos in parallel as batteries instead of the 5x 18650 slots of original case and charge them directly with 10Amps from my 90W LiPo charger. With 1x 2A output and 1x1A output this powerbank can feed much phones. In a wooden case, it also looks awesome with a external display for voltage in series with a button to check it with a press.
    I would be interested in using a 4S pack , capable as USB powerbank and as jump starter for my car including also a buck/boost converter to have a simple mobile DC power supply. I really like this chinese for example 200W buck/boost converters with a variable resistor to set max voltage and current. They are running all my Cree CXB and CXA Leds i used in my "projects" as a cheaper LED-"driver", sadly at 100-150W load they need already active cooling, at least i dont like hot heatspreaders.

    What about the Idea to make a proper 14-22V pack with at least 30Ah/4-6S, including a 230V or 110V (sinus) AC converter? like a "mobile" 230 or 110V AC "Powerbank"?

    Question: will adding more cells in parallel to a power supply increase its capacity or will it break something on the circuit?

      I think that depends on the PCB. The one I got had a maximum support of 18500 mAh. I think you're able to get a better one for a higher prince from eBay, Amazon or whatever site you prefer.

    Seriously, they make truly excellent products. Everything from Power Gear to Flashlights,
    Yup... Anker even makes EXCELLENT LED Flashlights!

    Made from billet aluminum with precision tooling, their $20-$30 buck flashlights come with a good quality 18650 rechargeable Lihium ion cell and BUILT-IN CHARGER (micro-usb female power input under the removable in the “end cap” / a bi-color LED displays charge status - easy to access but requires the user to carry a micro-usb cable to allow field charging)
    The device generates 3 levels of pure white (6500 deg. K) Illumination reaching a decent 1000 lumens in the “high” output selection.
    Runs up to 24-hours at “low” (100 lumens) and as low as 2 hours in the “turbo-high” mode and a sad recharge time of approximately 8 hours for a full charge. (with 5vdc /2.5a AC charger USB Charger with the cool ultra-short “flat” cable provided with each light)
    The last thing I wanted to include - though each light comes with a usb cable and nice, yet simple lanyard, as well as lithium rechargeable battery...
    Simply carry a spare or multiple spare batteries. Charge either inside the flashlight or use standalone charger.
    AND... Run out of charted rechargeable lithium batteries? Simply purchase some “Standard NON-Rechargeable CR-123 disposable cells. (10-yr dhtlf life .. approx $1-3 usd@ )
    THE LIGHT RUNS PERFECTLY ON 2 CR-123’s for up to 2 hours of perfect light on “high”.
    Remember - at around $25 bucks or so.. GREAT STOCKING STUFFERS!
    Sorry for the “advertisement”...
    I am a huge Fan-Boy of anything that provides great hardware for a great price.

    Most of cheap charging modules are unable to charge even 1Am battery. When I was trying to charge my Android tablet battery (4.5A), the module was heated and it was burnt within couple of minutes. Therefore, readymade charging modules are not trustable for long time projects. I hope it is better to use high quality chargers or make one by yourself to be suitable for the intended use.

    hello Scott
    I'm interested in electronics and I'm trying to learn some
    i have a question i hope you answer and it will be great if you explain it with a video of yours
    recently i bought a power bank to charge my phone it's cheap quality it is based on liion battery with step up converter to 5 volt but it's fake it have 5 cells each one 2200 mah so i decided to build a power pank using 9 cells with 3s bms (12.6 volts 6600 mah) and i connected with a car phone charger i was able to charge my phone 50% and voltage dropped in the 3s circuit from 12.6 to 12.2 i made some calculations to find out that i will be able to charge my phone completely up to 5 times my question is why the 5 cells in the step up power bank can charge my phone 1 time and the 9 cells 3s bms and step down is able to charge my phone up to 5 times (one thing to consider that i replaced the 5 cells with the same batteries i used with the 9 cells one) i hope you answer me
    thank you for the great videos

    I hate the charging speed of USB power packs. Have you ever built a high charge speed USB battery pack using a single prismatic cell like (www.batteryspace.com/lifepo4-prismatic-module-3-2v-40-ah-10c-rate-128-wh-----un38-3-passed-dgr.aspx). This is 3.2V 40 Ah with a max charging current of 3C (120A). I'm guessing something like this could potentially charge in about 20 minutes.
