USB 10 in 1Mobile Phone Power Supply Charger 18650 Battery Charger

Хорошая вещь для зарядки телефонов.
Брал для планшета, но ток у планшета 1А и уже сильно греется плата ( диод, дросель и кпд уже не тот).

it took about 10-15 days delivery which isn't bad. It came with no instructions though, but after a bit of fiddling I have got it running with some old ex-laptop purple 18650s (around the 2.6Ah mark) giving me over 5Ah of USB power. The unit comes with a mini USB cable that is used to charge the cells. That is to say it is both a power pack and an 18650 charger (for £7.34). I haven't tested the charging efficiency yet, but I have no reason to think it wont take the 18650s to 4.2v

I plan to use it for Long cycle rides as I can charge both my garmin edge 800 and my mobile phone (in theory at the same time). It also has a built in LED light, but its not bright. So for anyone wanting to use a mobile phone as a bike GPS, but can't due to battery life this is perfect.

Since there are no instructions:

Open the cover - its stiff, but it slides open.
Insert your 18650s I'm using unprotected cells which were from an old laptop and previously charged to 4.2v.
If your cells need charging then you can use the micro usb lead (input).
connect your output (standard USB) to the right cable (it comes with 10 or you can use your own).
Connect the target to the cable end press and hold the button until the red light comes on at the switch (the white light will/may also come on, while holding the switch) . It will then power the output 5v 1A (around 4.92v) until you disconnect the target.

My rough calculations it will extend the life of a mobile phone (normally about 800mAh) by 3-4 times the standard run time depending on the quality of the cells you use). Giving you the option of at least 2-5 charges on reasonable 18650.

I managed to charge an ipad and htc at the same time, but obviously the current is split between both (so its 500ma each).

Things I have tested/not tested:
- will it charge the cells and the target at the same time - No it appears to charge the target, but the cells don't increase in voltage.
- will it charge to 4.2v - not yet tested
- does it cut out when voltage drops or fully charged - not yet tested.
- will it charge more than 1 item at once - yes
