(not sure if something like this has been reviewed before)
it's labeled "smart USB charger" appears to convert DC12-36v into 4-ports USB voltage (supports QC2/3) and also displays the current being supplied (like a USB meter).
Hi HKJ,
Iâd like a slim, small capacity powerbank, around 3-4000 mAh or so. Iâm considering building recycling a smartphone lipo, but Iâm also having a look to ready options⌠these two for example could be interesting, in case you are interested in reviewing them:
Hmm, just my opinion, regarding the low-cost small-capacity powerbanks,
I think there are too many such kinds it may not be possible to do that much âstringentâ testing on them â low-cost unbranded items tend to not have that much quality control and while one batch may perform better, the next batch may easily change⌠at least based on my experience of them. Just my 2 cents worthâŚ
Actually, I have something that looks practically the same as your second link (the one here: https://www.gearbest.com/power-banks/pp_436972.html), someone passed it on to me (my relative got it as a âgiveawayâ souvenir from some club event).
The Tomo Epilot E4 is available from Gearbest (black is a few cents cheaper than white); maybe thereâs a generic coupon code somewhere to bring down the priceâŚ
While searching for the Tomo powerbanks, I came across other models too:
Tomo D2 (2x 26650) powerbank/charger: https://www.gearbest.com/chargers/pp_1524290.html
(specs list the input current @ 1A ; it will take a long time to fully charge 2x 5000+ mAh 26650 with this powerbankâŚ)
