Never Worry About Charging Your USB Device Again!
Today’s smartphones are so technologically advanced that it’s rare to see anyone with a professional-grade camera
anymore taking pictures or video. The smartphone fits in your pocket, has tons of memory and the 8+ megapixel
images are simply stunning. There’s even apps available that allow you to edit the images (or video) before posting
to your favorite Social Media outlet. So what’s the downside – maybe battery life? All the constant picture taking,
video taking, opening apps – it all takes a toll on battery life; some phones handle it well, others don’t.
I recently attended Axialfest 2016 and one of the Axial employees was streaming video to Facebook Live all day
long. He would stream up to 3 hours of video at one time on his iPhone, never once stopping to check the battery or
charge the phone. I asked him about it, and he showed me this awesome little adapter from ProTek that allowed
him to hook his iPhone up to any 2S-4S LiPo battery. AMain (ProTek is one of their brands) had a booth at Axialfest
so I raced over to snatch one of these up, but unfortunately they didn’t have anymore available at the time (they
were quite the hit). I’m not that easily swayed, so when I got home I made sure to order up a couple. Let’s take a
closer look at the “TakeCharge” unit.

What’s In The Box
Since it’s an all-inclusive adapter, the only thing included is the pre-shrinkwrapped TakeCharger adapter. You’ll need
a standard charging cable (you probably already have that) and a 2S – 4S LiPo battery (if you’re an RCer, chances
are you have that as well).
Performance
There’s not much to say about it – plug your phone into the
USB side and your 2S – 4S charged LiPo into the Deans-style
side and your phone should immediately pop up as being under
charge. The TakeCharge pulls the voltage down to an
acceptible level for the phone, so there are no worries about it
overcharging or pumping more voltage into your phone than
needed. The TakeCharge has an included low voltage cutoff
(6v) that helps protect 2S LiPo batteries, but won’t protect 3S or
4S packs – just take note of that.
To test the adapter, I charged my phone to 100% and the wife and I headed to the Orange County Fair. When we
arrived, I plugged into the TakeCharge adapter and dropped the 2S LiPo in my pocket. We were there for about 4
hours and I did 2-3 Facebook Live video feeds for a total of about 3 1/2 hours – my iPhone never dropped off, never
lost video connection and was at 98% when we left the event. The adapter was a little warm, but that’s expected
while pocketed during the 3 1/2 hour usage.
The second test was again at the OC Fair; my wife was doing a 2-hour painting demo so all I had to do was set it up
and walk away. This time, however, my iPhone only had a 58% charge – I wanted to see if this adapter could keep
up with the constant video feed as well as the secondary task of charging the phone. After her 2-hour demo, the
phone was only at 64%, so while it does keep it steadily charged, constant usage does prevent it from quick-
charging the phone.
I started off with a DuraTrax Onyx 5000mAh 2S LiPo pack that was fully charged, using it for over a week for various
videos; 2-3 3+ hour sessions and 20ish 15-20 minute sessions. Prior to completing this article, I re-charged it and
was astonished to find that the pack only took 2290mAh, meaning it still had around 2710mAh left in it. That’s a LOT
of usage time between charges – I’ll probably run out of storage on my phone before the battery finally dumps!
Let me also note that this will work with more than just phones. Basically ANY USB-powered devices are
compatible; iPads (or other tablets), cameras, GPS devices – if it can be powered by a USB adapter, the
TakeCharge is your guy. This makes it a very versatile piece when AC power is not accessible!
Conclusion
Never Worry About Charging Your USB Device Again! Today's smartphones are so technologically advanced that
it's rare to see anyone with a professional-grade camera anymore taking pictures or video. The smartphone fits in
your pocket, has tons of memory and the 8+ megapixel images are simply stunning. There's even apps available
2/3
3. that allow you to edit the images (or video) before posting to your favorite Social Media outlet. So what's the
downside - maybe battery life? All the constant picture taking, video taking, opening apps - it all takes a toll on
battery life; some phones handle it well, others…
Bottom Line: Now I know there are a ton of different portable charging devices out there, but you're going to be
hard-pressed to find something that uses a battery pack similar to what we RCers have lying around - and for only
$10. As RCers, we all use our phones at the track for something; looking up setups, snapping pictures of our
gorgeous rides or sneaking some video of someone's prototype car or parts (or am I the only one that does that?).
It's only $10. Get one - I mean really, why should we have to worry about battery life when this adapter makes it so
easy to keep our portable devices charged?
