Preparing for another disaster (Solar Charger for cellphone/smartphone/laptop)

[remzam]

remzam,


Nakita sa youtube mga 4years ago na yung video, pinapakita mga portable solar. Meron medium (1,200pesos) and small (800). Isang set na ganyan price? Ito post ko video ang ganda diyan ni lyn ching.





Isang set na ba yan or yung panel lang? Magkano na presyuhan ngayon?

San galing yung price? Panel pa lang yan. Kasi isang SLAB pa lang mga 600-800 na yun. Raon price pa yun.

Tsaka kalokohan yung pinakita sa link mo with the very small panel. Na portable daw? True portable systems hindi ganyan. Foldable or flexible panels na light weight. Yung sinabi nya sa dulo na portable, you don't want that. Battery pa lang nyan bigat na. Unless you go LiPho.

Portable lang yan kung ilalagay mo sa kotse mo.

Dun sa plano mo for phone charging, rough estimate ko for your system mga 5k pataas.

Kung sa bahay mo lang naman, go for bigger panels. Tutal naka babad lang sa bubong mo yun. Kung maliit na panel, bago pa ma fully charge ang battery mo (na iba iba rin ang capacity, parang power bank) baka used up mo na for charging ng devices mo.

Yung batteries used in solar generators, iba rin, ideally deep cycle. Mas matagal buhay and made for charging and recharging. Battery kasi natin sa kotse, parati puno yan. Deep cycle batteries are more expensive than regular ones.

Eh yung nauuso solar powerbank, enough ba yan para maicharge ko yung enelopp charger tapos paano ko pala maisasaksak yun.

remzy,

Ito may nabasa ako online. Solar ba ito 18650 na powerbank?

That depends entirely on your charger, and how many batteries you'll be charging. It will likely be somewhere around 5-10W for a 4 cell charger. So you'll want at least that much power out of your solar setup. Double it, at least, to account for inefficiencies.

Or just use a small setup to charge a USB powerbank. Then use that to power your Eneloop charger. A 2-cell 18650 powerbank should be able to charge 4 Eneloops. I'd go with a 4-cell powerbank to be sure, though.

Yung mga solar power banks bago mo mapuno yun lagpas isang araw under heavy sunlight.

Mas novelty pa sya kesa efficient device.

rem and vod

Ano maadvice nyo ok na brand na 4cell 18650 powerbank. (wala pa ako smartphone and slow ako sa pagkakaintiindi pag dating sa electronics ah so alalayan nyo ako.)

Ano meaning nito USB-out?

"USB-out: 5V 1A only when plugged in (Not a powerbank feature!)"

[Vodka]

"not powerbank" means the USB is dead if it's not plugged to the wall. doesn't work as a powerbank

this is my favorite powerbank by far. Miller ML-102. and as many 18650's as you can afford. 5-bar fuel gauge is convenient to read

LOL it's a single-slot charger/powerbank. those are just loose cells

Punta ka Raon dami dun solar set or sa HMR meron din medyo good quality, then bili ka ng LM7805 voltage regulator sa Deeco o Alexan then kabit mo sa 12V VRLA battery ng solar mo. Then buy ka online ng charge controller ng 18650 like this one https://shopee.ph/2Pcs-5V-1A-18650-T...iABEgIgQvD_BwE, voila! meron kana charger ng vape mo. You may now hug the tree..lol
