Hi i have a colman hot water on demand but have lost the 240 volt charger.i was wondering what milliamps or amps it needs to puchase another one from a elec store.

Most lithium small radio batteries are 3.6 volts. If AA or AAA batteries, multiply by 1.5 volts. 4 batteries = 1.5 * 4 = 6 volts MAXIMUM. Rechargeable batteries are 1.2 volts. Your charger would be a much higher voltage because it takes power to "push" the charge into a battery. You didn't say, so I am assuming you want to operate the radio with a wall charger. I've done this by soldering the wires to the battery contacts. You need a higher voltage than 3.6 volts, but milliamps is more important. You need enough milli amps to get the radio to transmit. Too much and it frys, literally. So, this is all on you to decide if the risk is worth it. I use a 5-6 volt power supply set on no more than 1 amp (800 ma is my favorite size) 1 amp = 1000 ma. Let us know if this helped!

No.
Fold-back elements are low-watt-density, so element does not burn out as easily since heating is spread across more surface area. But recovery remains 16 gallon per hour.
20 amp breaker and 12 gauge wire: max 3800 watts
30 amp breaker and 10 gauge wire: max 5800 watt.
4500 watt element heats 20 gallons per hour.

Instead of changing elements: Set thermostats higher so more cold is added to hot water, and then you have more hot water available inside tank.

The DC18RC are most likely to charged the BL1830 battery, which is the most popular of 18V Makita power tools. It is a Li-ion battery.

And the DC18RC battery charger has two volt 110 Volt and 240 Volt.

The 240 Volt DC18RC charger can replace model DC18RA & DC18SD because of its improved performance and full compatibility with Makita's NEW 'Star' labelled batteries that communicate between the tool, battery & charger. And, it is a fast charger.

It can charge a Makita BL1830 Battery in approx 22 minutes.

But, I do not recommend to convert a makita charger model DC18RC at 110 volt to 240 volts.

The reason is as below:

1. This will void product warranty ! If you follow this mod, you do it on your own risk !

2. There are several comments that described
same model # but with different design and components.
Please beware that this mod might not work on your charger
or worst, will damage it.
Only perform this mod if you know your way around with electronics !

Hi,

Rule of live by: Each unit must have its own breaker. Cooktop needs 30 amps and a double oven needs 40 amps. Never combine the unit as the amps flow if too high can cause the wires to melt. I hope this helps. Be safe!

Hello, I found that a 12 volt, 1500 milliamp charger for a Boston Acoustics set of speakers works to charge this. (halfway charged, today). So, I 'm sure on the 12 volts, and hoping it will be enough power to fully charge. B

Sounds as tho you are only getting 120 volts versus the 240 you should have. Your breaker needs to be at least 30 amp double pole rating. 240 volt

As long as the hot water tank is no more than fifty feet from the panel, you will need 10/3 with ground wire, wire staples and a 30 amp double pole breaker. Be sure to purchase enough wire with about 4 feet extra to allow for connections.

Be sure to fill the water tank before turning on the power. To be sure it is full, run water through the nearby faucets, turning on the hot water faucets or both to be safe. If you fire up an empty hot water tank you will destroy the heating elements almost instantly.
