I have used this charger since 2019 and think it's a great value for the price. I like the quality and ease of use - works great! For this I give it 5 stars. However, I did run into one little issue, and it has to do with input voltage.
The charger comes with an AC power cord as well as a separate power cord with coaxial plug at one end and alligator clips at the other for portable field use, say, connecting to a car battery, etc. For field use the charger is rated from 9 to 12VDC input. Believe it! The first time I tried connecting the charger to my field box battery the charger displayed ERR9, which, according to the manual, turns out to be an input voltage error that exceeds maximum limits. To test what this maximum input limit was, I connected the charger to my benchtop variable power supply and slowly turned up the voltage to just past 12 volts. At about 12.2 -12.3 volts the unit beeped and ERR9 was displayed. This meant the charger could not be run on a standard 12-volt lead-acid battery (usually 12.6 to 14.2 volts). Fortunately the charger seems well protected and no harm was done to the unit.
We have solar-powered charging carts with lead-acid batteries at our flying field. To use this charger on the solar carts I purchased an adjustable DC-DC Buck-Boost converter/regulator - for roughly $15 on Amazon - setting the output to about 10.5 volts. The charger works like a champ on the buck/boost converter with no stability or overheating issues. Back in business!
In general, if you're planning to use the charger only from the AC outlet, I highly recommend this product. Just be careful what power source you plan to use other than the AC power cord.

Venom strikes again!!
Wow! This 4-in-one charger is feature packed and awesome! Small, lightweight, compact, durable and very well built!Out of the box I can feel the quality. Not flimsy like other chargers I have owned. Rubberized feet grip the desktop/countertop so it stays put! Softer tones unlike the annoying tones from my other chargers. Great internal features too. Multiple battery type plugs mounted right in the face of the charger so no need for additional wires. Full led read out that is easy to read. Shows battery voltage as soon as you plug in the battery. Adjustable in .01 amps from .01-1.0 amps. When charging, alternates from voltage to amp setting. Works just like other chargers in regards to changing settings so very familiar and easy to use. One thing I really liked was when battery is done charging, you get 3 indications. Audible tones, flashing "full" on screen and green light on face! Cool! Has AC and DC capabilities. Oh and one last thing...super cool light up "VENOM" logo on the front!!! Added coolness!As if this wasn't enough for you to decide on this charger, Venom is supporting this charger with a "limited lifetime warranty". That's HUGE! Electronics with a big warranty says tons about their confidence in this charger...im sold!If I had to complain aboit this charger i would say 2 things. 1) it only charges 1s batteeies, I would love to see it with 2-3s capabilities and 2) I need more batteries!!!In my personal experience, anytime I have ever had an issue with a Venom product or I just wanted to call and ask questions about products, I was able to contact a customer service rep every time I called. Based in the US I don't have to worry about staying up until midnight to reach a CS rep...and I do it over the phone (or email)! I love Venom's service after sale and Customer Service department, second to none! All in all, I'm very pleased with Venom's newest innovation and would buy again if need arrises!Thank you Venom for making this a "no-brainer" purchase! I look forward to years of use from this charger! Woohooooo!!

This thing is pure sexiness and unbeatable quality. The whole thing is a very nice matte black and feels like suede (i swear!) Very sleek feel along with some very nice silicone feet for grip. Front has the venom logo that lights up red and creates this awesome effect on wherever it sits. The charger is very easy to use with a simple channel select button and buttons to lower and raise the charge rate, along with another button to start and stop charging for each channel. Fan on the back ensures that the charger stays cool during operation aswell. The major thing that really popped out to me was an immediate punch of awesomeness! Not only does it charge the most commonly used MCX batteries but also JST, MOLEX and even the MCPX for those micro helis. Another thing is this thing not only does LIPO but ALSO does LIHV! Yeah you heard that right. LIHV!!!!! Simple switch sets the chem settings for charging to make it safe and easy. The manual is extremely detailed with both diagrams and detailed shots of the operation screens. And the Limited Lifetime Warranty makes it a no brainer honestly. If it fails within the year they will either repair or replace it and anytime after that they even credit 30% back if it fails towards anything else Venom you may want to buy <--- this alone made me super happy as it is lolReviewed in the United States on August 30, 2017
