That seems awesome but then you put this comment aboveā¦
āBefore using the charger for a 4.30 volt cell I will strongly advice to check the charge voltage with a DMM: Connect a DMM parallel to the battery and check that the voltage stays below 4.35 volt all the time while chargingā
@hkj
I already have seen the review of the LGcell, but I asked if you will also test the one in your picture which is a newer version. I wonder if they have changed something internally too or just the shrink wrapā¦
New:
I'm a bit late to the party but I just ordered one from Mountain Electronics. It looks like the perfect travel charger with very decent features. I should have it on Monday
Thanks :) I have 4 other Xtar chargers (WP2, MP2, and 2 VP1's) they've all been great. I like that it's small and does 4.35 volt cells which I have, and the USB output will sure come in handy every once in a while.
I will be receiving an XTAR SP-1 that I won for $16.00 from a dealer with few reviews on Ebay, and half of those for clothes (or scarfs), called xtarshop, do I have to worry about fakes?
I know that this is an old thread. But I recently got an SP1, and decided to give USB charging with LiFePO4 a try. With a fully charged A123 Systems 26650 (2300mAH version), I was able to charge my iPhone from 10% to 80% charge before low voltage protection kicked in. And this was while using the phone a decent amount in the process. So I might be able to get a complete charge if I leave the phone alone while charging. I should also mention that the battery gauge basically doesnāt work while charging with LiFePO4. Due to the lower (but more stable) voltage of LiFePO4, the battery indicator flashed red pretty much the whole time you are charging. This indicates less than 25% charge, but is showing this because the charger is really designed for USB charging from 3.7V batteries. However, the charger WILL work with LiFePO4 as a USB charger, even if it canāt use the full capacity of a LiFePO4 cell.
Just picked up one of these from RMM to charge a couple 4.35V LG cells I have and to see how it would deal with recharging my busy box(iPad mini). With the cell starting at 4.3V it brought the charge state up to 40% before the led turned red. I pulled the cell and measured it at 3.7V so it would not have added much more. Seems like a nice charger and should be for the price and nice that with the 3 different charge rates it also charges shorter cells. I donāt think I will use it for 10440 or 16340 even though they would fit but great for 18350-26650 and 3.2-4.2V. Iāll edit this post when I try it out in my iPhone 5C.
