Hohm School 4 Bay Battery Charger by Hohm Tech
USB-C 4 AMP continuous power supply and stability made it possible for Hohm SCHOOL4 to do what it does so well.
Thinking outside the box, while keeping simplicity and user-error prevention at the forefront with safety features. 18 months of R&D led us to develop an extremely capable charger that makes other chargers look stupid. It has a 3-tier amp BLD (battery length detection) System; has a variable input voltage IPR (input power regulator) feature. This ELIMINATES USER ERRORS, and keeps them and their li-ion batteries moving forward without delay. This is simplicity at its best, while not forfeiting usable amperage or precision.
There is no need for a screen on this charger. It is 100% autonomous. It is equipped with our BLD1 System, which automates the step up/down output so both small and larger cells charge at proper rate (0.5A, 1A, 2A per channel with 4A total distribution). Even li-ion batteries with a PCB/PCM3 are easily balanced to the correct voltage. This ensures today’s small li-ion batteries chemistry integrity is not compromised, allowing them to get the cycle life they deserve.
Applying more forward thinking targeted towards safety & performance, we integrated input voltage regulation. This is safety 101 here. This allows charger to not stress or damage USB adapters no matter the power supplying device. Fact is simple: today’s li-ion batteries need precise voltage and amperage delivery to ensure long reliable performance & life…Say hello to Hohm SCHOOL4, the ‘Professor’ of Chargers. 18650

Fits my 21700s easily. Longer discharge from my batteries. Could come with a 4A wall plug. Luckily I had one. 4A is kind oflarge and rare for a USB outlet.Herbert O.The battery charger is okay, but I was under the assumption that I could charge regular batteries also (like AA and AAA).JasonT.This is an amazing little 4 slot charger. Plenty of overcharge protection and very fast charging on the two outer slots. If you don’t mind not being able to tell exactly where your charge or volts are at and you just always charge to full, you can’t go wrong with this charger. Cameron T.Not being petty but it’s an utterly boring display and a very slow charge. Their last model HD a beautiful display and charged faster. I have it hooked up to a fast charging block and I’ve tried a normal. Either way was several hours to charge the batteries. Plugging my mod into power via USB charged twice as fast… what gives? Hohm when backwards in technology and convenience.Tammera S.GreatDavid CowanMolicell BatteriesBest batteries I have ever tried.Choonhok LimHohm Tech School 4 Bay Battery ChargerSo far, pleased with productMichael ZimmermanJust what I wantedThe product description sold me. I like that there are no dials or gauges. It’s my first one so nothing to compare it to but it works awesome and the price was fantastic.Justin ZanettiThe bestLove this charger. Always feel safe and secure using anything from Hohm tech and this no different.William SmithGreat chargerthis thing is really fast and very accurateKim PearceThanksMove convenient than my two-bay and was here quickEdgar Perret-GentilGreatI got this one is for one of my buddies since I love mineDavid GentryHohm work batteryI have gotten several Holm tech batteries and they have all been great except one hohm work one will not charge at allDavidDAVEA LITTLE SMALLER THAN I EXPECTER BUT CHARGED GOOD.CharlesHohm Tech School 4 Bay Battery ChargerNice little charger, did not come with charging adaptor and the cable could have been a little longer. Takes 21700’s. Fast shipping!
