Best Wall Charger for this Price Range that I've seen to this date 7/15/14. 7.8A of Total Output.
on July 15, 2014
This is my review of the HooToo HT-CT01 40W 4-Port Charging Station w/ OTG USB Access Function. I was provided a sample by the manufacturer to give my personal evaluation and opinion.
My Initial Impressions
7.8A total output is impressive for this current date and time of available wall chargers. This is 2.4A for tablets, and 1.5A for smartphones.
I previously evaluated the RAVPower Bolt that was a similar featured wall charger and it had a total output of 6.2A (2.1A for tablets, and 1A for smartphones). They currently both have the same sales price of $19.99. But the extra with the HooToo HT-CT01 is that it has an OTG port which is a new feature for the price range of these wall chargers.
** NOTE: It's important to read the Amazon Product Page and User Manual before using this product.
There's 2 ports labeled SMART. What that really means is that it can charge most tablets and smartphones. My iPad Air OEM charger is 2.4A and this HooToo port matches the OEM current output, so that's great. The ports labeled iPhone and Android each take 1.5A total output. Do not let the labels fool you. You can charge any smart phone, cell phone, or bluetooth keyboard with these ports. I contacted HooToo support and mentioned they should change the naming convention on the wall charger labels to not confuse people. In the end, it's 2 ports that are 2.4A MAX and 2 ports that are 1.5A MAX.
Something nice to note is that all ports have an intelligent chipset that allows it to auto adjust the current to devices plugged in. So for example, if you have a device that takes 1A current output and you plug it in the 1.5A port, the port will draw only 1A current to the device. Similarly, if you plug that same device to a 2.4A port, the port will draw only 1A current to the device, so you do not have to worry about it overcharging past the limits of the electronic devices.
During my first test charging devices, I charged 2 cell phones, and 1 bluetooth keyboard. I checked on them about 20 minutes later and to my surprise, holding the CT-01 is comfortable. It didn’t feel hot like the last wall charger I evaluated.
However, during my next test charging devices, I charged an iPad Air, iPad 2, and two cell phones, which nearly maxed the total current output, and when I came back to check on it 20 minutes later, I felt the top and bottom of the wall charger get very hot to where it wasn't comfortable to hold and grip. It concerned me at first, but I asked HooToo support and found out that it is recommended to let the device cool down for 10-15 minutes after unplugging. The lifeline of the device will not be shortened due to this observation of continuous usage.
It is possible to charge 4 smartphones simultaneously across all 4 ports of this wall charger since they would be at or below the MAX current for each port. However, it is not recommended to charge 4 tablets simultaneously as it can damage the product. If you have more than 2 tablets at home, I suggest you buying 2 of these units to share in the family household.
You can charge iPhone, Android, and Windows Phones to the 2 ports labels "iPhone" and "Android" interchangeably. What matters is the 1.5A specification for those ports.
A mistake that I made was that I was not aware that this product's OTG function is not compatible with Apple devices. It only works on Android devices currently, so when I connected my iPad Air using the lightning cable to the OTG port and used a USB flash drive or hard drive, nothing happened when connected. This is by current design. I hope future models have support for Apple devices.
This product does have a "short circuit, overcharge protection and surge protection" built in to protect devices while charging. It is not stated in the User Manual, but I asked this from HooToo support and got the verification. I'm glad HooToo cares about safety when designing its products.
1) I think it would be better if the ports were labeled with the Amps for the more technical people who understand their devices. It makes it strange because why are the 2.4A ports labeled “Smart” and the 1.5A ports” not also labeled “Smart”?
It makes people unsure which port to plug in bluetooth speakers, headsets, and external battery packs. This is not mentioned in the user manual. I can understand a product’s current requirement, but it may not be very universally understood for other users looking at the naming convention of the wall charger ports.
2) When you first power on the wall charger, after a few seconds of plugging it into the wall, you’ll see the LED icon turn blue to indicate that it’s ON. What would be a nicer feature is if each port had its own light that was either colored red, yellow, or green to indicate if it’s OFF, passing current through and charging, or when the device has fully charged and no longer passes current through.
3) I suggest a ventilation system designed for this product such as a fan or heat sink to dissipate the heat quickly and during the charge process.
4) I suggest the power cord be designed to charge with a longer cord by at least 1 extra feet of distance. I had a hard time positioning this wall charger around my desk or table from the ground where my surge protector or wall outlet was because the power cord is short. If I leave the wall charger on the ground along with my electronics charged on the ground, then that's not a problem that is noticed. But, if I want to use the OTG or charge devices with the wall charger positioned on my office workstation table, I cannot wrap it from the back of my table and bring it forward because there's not enough cord length.
5) There should be mention of other electronic devices that connect via USB for charging in the User Manual, such as bluetooth keyboards, bluetooth speakers, headsets, external battery packs, and so forth. I can understand a product’s current requirement, but it may not be very universally understood for other users looking at the naming convention of the wall charger ports.
I give this product 5 stars out of 5 stars because I'm impressed with the total current charging capacity, the competitive pricing considering the features it has including OTG, portability, and efficiency. I tested using this product on many different electronics and ran into no issues besides the product getting hot, which is normal.
1) Fits into messenger bags and shoulder bags easily to carry around when on travel.
2) 7.8A total current output is good enough for individuals. With two of these units, a family of 3 to 5 should have enough to be sufficient.
3) Auto Intelligent smart chip makes it safe to charge devices without worrying about overcharging the electronics.
4) OTG port for Android allows connecting media to smartphones and tablets, a new feature that I've seen with wall chargers.
5) One plug used in a wall outlet around a building or house compared to 4 plugs normally used to serve the same purpose.
1) Ideally, it would be nice to have all 4 ports capable of charging 4 tablets safely without product damage.
2) Hot product while charging and after charging needs to be resolved for better handling safety.
This product is good for roommates, or for more than one individual, such as families of 3 and up.
This product is good for travelers who may find that there's times when only one plug is available in the wall outlets of hotels and meeting rooms
This product is good for study rooms at libraries or other places of similar type.
Thanks for reading my review and I hope that I was helpful.
