@SubhraneelS•Read Step 1 under "Three major types of powerbanks"
@LibbyfrancisThat depends on the device you use your powerbank for and how often you use it for.
Most powerbank can be charge on 1 amp 5 vdc power adapter and your Vox 24000 mah will take 30 hrs to fully charge it.•trying to fast charge it on a 2 amp 5vdc adapter will result to damage in powerbank circuitry-refer to your user manual if it supports 2 amp 5vdc charger.•Read STEP 1 of this instructables.
Nice project-i suggest to use Mechanical Mod instead of a regulated box mod.To fire it continuosly without the ten seconds cut-off which most of the regulated box mod for vaping has this feature.,Some has 15 secs cut-off.And use a rebuildable dripping atomizer with deep ejuice well.
@SpandanB3as long as you used the biconvex lenses in the binoculars-i think it will work.
@ashu1paYes-i tested it and it works on large screen smart phones.
@Vikas kumar 56Yes,you can use your 75mm lenses,but i can imagine how big your VR would be.,I suggest you look for smaller lenses,you can get lenses on telescope toys.i made one using macdonald happy meal telescope toy that had two 25 mm lenses.
@SerbanPA running device generally consumes power,therefore if your device is actively in use during the process of charging with your powerbank,the charging performance may not meet the expectation.Your device maybe damage when you slipped it on the floor.•Read step 8 to 9 ,and read the POINTERS on the last part of this instructables.
I suggest you use new empty plastic bottle cut in 25mm,and follow the steps.And use purified water to fill those home made lenses you made.,Double vision occurs when both lenses arent properly in correct focal distance with your phone screen.
That's expensive for just a chip module or a buck converter.,though it can discharge up to 3 Amps capacity.,Yet you can buy a high capacity powerbank with that.,But if your project requires more than 1 Amp supply.,you can go ahead and get it.,But if you're going to need it as regular back up charger for your phone & other devices that is very pricey.,Here you can buy a powerbank with that price:https://www.amazon.com/s?ie=UTF8&page=1&rh=n%3A7073960011%2Cp_36%3A2491155011
@WesM11i bought it from a electronic store near my place.,you can buy it online(almost similar to the one i use here)you can find theStep up power modulehttp://www.ebay.com/itm/DC-converter-3-7V-to-5V-800mA-MAX-USB-Mobile-phone-Charger-Power-Supply-module-/321597640860?pt=LH_DefaultDomain_0&hash=item4ae0b6909c#rpdCntIdhttp://www.prodctodc.com/dc-to-dc-15v-to-5152v-stepup-module-power-converter-for-mp3-mp4-phone-p-66.html#.VNWJomJdac2
@NatenBThanks!,i just use my powerbank to charge cp & to power other devices that supports 5vdc input.,havent tried it on headset,rechargeable mouse or smatwatch.Sad to say that most of electronics today are manufactured in china to cut labor costs..,but quality & purpose of their electronics depends on brands,chip module used in it.
@S--0--Syou have to modify the google vr cardboard to fit your 50mm lenses on it.,and put it on a flat surface to get the correct "Focal Distance" between your lenses & cp screen.(as i made it using E.V.A foam with 45mm lenses on it.
