C’mon, guyz, $20 wholesale… This charger meant to be better than SP2 and I didn’t see SP2, after almost 1 year on sale, to cost lower than 25 bucks. Of course we all want the cheapest price, but sometimes it’s impossible. I’d like to thank Jason to share this charger with us Definitely the lower price will attract more buyers
The thing that brought my attention is that batt status. Both batts are at 3.81V but bottom batt status is very different!
I’d like to know how does the charger knows that And yes, mAh counter would be awesome (like LaCrosse BC-700, etc)
The battery gauge is a rolling indicator. While it’s charging, it will fill from left to right with it becoming increasingly more solid (eg. less bars “scrolling”). It does come with the car charger so at least they give us “something”
You can not use a photo to see the status on, the bars does "run" while charging. The minimum number of bars will be the status, but it will always show something between minimum and 5 bars.
The added value of the voltage and current (fixed = just replaces positional current selecting switch) display is close to zero and cannot justify the price. Doesn’t provide discharge function, capacity measurement, LiFePo support, USB input/output. I own MAHA, XTAR WP2 II + MP2 but this new VP1 is a kind of Mickey Mouse improvement and I would rather buy a nice hobby charger for the same price.
I’m sure distributors were asked for input. We suggested in this order:
Capacity count (charging)
LiFePO4 or NiMH support
USB output or input
I also have nearly every recent charger under the sun but this is a plus because it’s a step up from the Cottonpickers BUT the same cost Cottonpickers can do NiMH
Note we suggested a close price point to this contingent upon the features above. Note that at this price it’s still competitive for the voltage readouts (as compared to others like Cottonpickers).
If it passes all the tests (I would expect it do, but I need to do some more measurements), then there are two things in favor of it:
The display, the obvious is that it can be used to see the charge state of the battery, but it can also be use to estimate the age of the battery (Not in years, but how word down the battery is).
If you are using 16340 and especially 10440 cells, the 0.25A range is very useful.
Generally I would expect it to be more expensive than the XP2, a custom made LCD display does cost more money than 3 leds.
Why is it that generally, charging a 16340 at 0.25A is preferred over 0.50A, while charging a 14500 at 0.50 is totally acceptable even though they are both 4.2V 750mAh cells?
