3A, 30V, Host-Controlled Single-Input, Single Cell Switchmode Li-Ion Battery Cha (Rev. A)

7805 experience deceived us.

The simplest way to reduce the voltage of a DC supply is to use a linear regulator (such as a 7805), but linear regulators waste energy as they operate by dissipating excess power as heat. Buck converters, on the other hand, can be remarkably efficient (95% or higher for integrated circuits), making them useful for tasks such as converting the main voltage in a computer (12 V in a desktop, 12-24 V in a laptop) down to the 0.8-1.8 volts needed by the processor.

ETEKCITY 1.0/2.1 A 5V 12V mobile charger testing complete.

Little or no heat dissipated even at max current! How did they do it?






1 15 and 5 Ohm power resistor setup.

2 .88A test of 1.0A ETEKCITY port.

3 Max current of 2.16 A. Important is that ETEKCITY is only at 22oC.

Linear regulator would be dissipating about 12 - 5 = 5V times 2.16 or about 15.2W.

So ETEKCITY appear to use high tech method of current and volatage regulation?

4 1.0A charging port test.

Harbor Freight free digital multimeters make these experiments possible.
ETEKCITY mobile charging port is impressive both from a regulation standpoint and low heat dissipation.









Adreama 1.0A regulated well but dissipated a fair amount of heat.

Observing grid, solar and USB charger voltage output has caused bill to change thinking about battery charging. And probably understand what the battery charging designers have in mind.

Destoying CR-V alternator because of bad batterywhich cost several hundred dollars as well as VW rabbit alternator replacement over more than 20 years also plays a role too.

Microcontroller/microcomputer power needs experience also led to bias that rock-solid voltage voltage is required.

Assumption in below videos is that it is bad for charger voltage to vary out of 5V USB specification.

Bill appears to be wrong.

But let's look at the videos before criticizing. And don't believe opinions expressed are correct.

1 Float charge Werker 12V 9Ah AGM start.

2 Float charge finish. Over night charge.

3 Adreama USB charger power consumption measurement.

4 INNOVA 3320 autoranging power resistor measurement. CORRECTION: Ohms, not watts.

5 Adrema outputs about 1/2 A.
Assumption voiced that being outside USB 5.0 for battery charging is bad in very likely incorrect.

We are in learn and think modes.
6 INNOVA 3320 autoranger does it thing with 5 Ohm 12W resistor.

7 5 Ohm 12W resitor tests. Audio correction: Ohm not Watt.

8 Video so embarrassing it was almost not posted. Load resistor connected to wrong white wire. :( But mistake discovered. :)

9 Load resistor properly connected. Do not believe that statement that we have trouble.
USB voltage specification compliance bias does not apply to battery charging.

10 It is NOT FAILING!

11 Second Adreama is NOT FAILING!

12 USB voltage compliance does not apply to battery charging.

13 Harbor Freight USB charger tested at 500 mA and open.
Seeed DSO [digital storage oscilloscope] Nano V3 battery did not work on arrival from China. But Nano works fine powered by USB.


DSO Nano mobile apps could use mobile USB charger and 12V battery.

Concern is that Nano could be damaged by USB overvoltage.

Another reason for USB volatge specification bias.

Nominal 3.7V Li-ion Onite cell phone battery seen charged to 4.21V.

USB charger must supply more than 4.21V to have current flow into battery.

Adreama USB charger may able to supply this voltage at 1A.

Draw of .41A observed charging a 3.7V 1200 mAh Li-ion battery with a Tracfone LG840G cell phone on the Battery full? page.

Videos 10 and and 11 show the Adreama at about 4.3V, maybe slightly lower at about 1A draw.

12V -4.3V = 7.7V drop across the charger.

7.7V * .41A = 3.157W approximately must be dissipated within the regulator.

1kWh = 3412.14162 BTU.

Does the 107.6o F temperature increase from 68o F seen in videos 14 and 15 compute? :)

Reduction of 12v to 5v using 7805 linear regulator by Sandia labs technician Konrad Roeder lecture in the early 1980s stressed the importance of the amount of current passed though and voltage drop.

Heat sink may be required.

But there may be some new method to reduce heat?

reduce 12v to 5v.

HooToo 7 USB ports, two charging ports transformerphotographed with

Logitech webcam.



INPUT: 120-240v ~AC 50-60 Hz, 1.5A
Output 12V -DC 5000 mA.

2.1A charging port must drop the 12V to 5V. That's 7V with maximum 2.1A from just that one charging port?

7 * 2.1 = 14.7W must be dissipated for max draw on just this one port?

1A charging port must dissipate 7 * 1 = 7W at max draw?

USB 3.0 data port must dissipate 7 * 1/2 = 3.5W? Maybe even 7 * .9 = 6.3W?
Max. current 0.5–0.9 A (general);
5 A (charging devices)

14.7 + 7 + 7 * 3.5 = 46.2W?

Or even

14.7 + 7 + 7 * 6.3 = 65.8W max must be dissipated within the HooToo hub?

According to The Guardian, "the Casio F-91W digital watch was declared to be 'the sign of al-Qaeda' and a contributing factor to continued detention of prisoners by the analysts stationed at Guantánamo Bay. Briefing documents used to train staff in assessing the threat level of new detainees advise that possession of the F-91W – available online for as little as £4 – suggests the wearer has been trained in bomb making by al-Qaida in Afghanistan."[4] United States Military intelligence officials have identified the F91W as a watch that terrorists use when constructing time bombs.[5][6][7][8][9]

"Back in 1995, Ramzi Yousef and Khalid Shaikh Mohammed tried to blow up the Pope in Manila[2]. Ramzi tried to make a bomb, accidentally set his hotel room on fire, and fled. In his recovered laptop there were instructions for how to use a Casio F91w as a bomb's timing device.

As a result, the watch was linked to terrorism. And as a result of 'that', the Department of Defense has listed possession of a Casio F91w as a reason to detain 27 Guantanamo prisoners indefinitely[3].

Looks difficult to me.

Even under a magnifying glass.

Belkin 7 port powered USB RMA trouble cause HooToo support to send
a 7 port with two charging ports powered hub


 

Battery charging interests caused us to measure voltage of USB output for a Harbor Freight 12 V automotive plug, then both Belkin 2.0 and HooToo 3.0 ports.

USB output is included from three Harbor Freight inverters. Manuals for all stated that the output is limited to 500 mA.

Disaster almost.

Measuring voltage outputs from HooToo and Belkin hub caused both Touro and Verbatim disk to disappear as well as DSO_NANO _V3 from WE.

All are back.



But DSO_NANO_V3 does not work through Belkin hub now. Why?

Plugging DSO_NANO_V3 into Gigabyte motherboard worked.

USB voltage and possible currect breakout cable under construction using old printer cable.
 


Reason we are building cable.



CAUTION Risk of fire. Do not use fuse rated higher than 3 Amp
 
The specs for a PC PSU are for +/-5%. So the actual output of the 5V rail can be anywhere from 4.75V to 5.25V, if its a good quality PSU. Cheaper PSUs can be as bad as 8% or 10%. But the PC and USB devices will still operate fine at that level. As mentioned the voltage out the end of the USB cable will be slightly lower due to resistance.



High.

HooToo USB 3.0 experience reshaped our thinking about desktop computers.

Ease of upgrade from Internet software polluted 320 GB to 1 T WD SATA drive was simple. As well as was Windows XP install.

Laptops have disadvantage of only one hard drive.

Removal of Internet garbage software is difficult, if not impossible.

Thank you HooToo, Williams and Sunvalleytek video.

Support, the way it should work.

A fun and educational experience.

Desktop vs laptop perception changed. Garbage software may destroy laptops? Preloaded laptop software is a SUPER-BAD idea.

Reason is that installing new larger hard drive then reinstalling windows is the easiest and least expensive way of getting rid of garbage software.

No battery charge problem.
