How to choose the right inverter
When choosing an inverter, pay attention to both continuous power and peak power.

The inverter’s continuous power must be greater than the rated power of the connected device.
However, some inductive loads (e.g., power tools, air conditioners, refrigerators) require significantly higher power at startup — usually 3 to 12 times their rated power.
In these cases, the inverter’s peak power must exceed the device’s startup power to ensure safe operation.

Example:
Question:
Can a 2000W inverter be used with a 500W handheld drill powered by a 12V / 60Ah battery?

  1. Calculate maximum battery power:
    12V × 60Ah × 0.8 = 576W > 500W → ✅ sufficient

  2. Determine device type:
    The drill is an inductive device → startup current must be considered.

  3. Compare continuous power:
    The drill’s rated power is 500W,
    the 2000W inverter has continuous power of 1000W → 1000W > 500W → ✅ sufficient

  4. Calculate startup power:
    Typically about 3 × 500W = 1500W
    The inverter’s peak power is 2000W → 2000W > 1500W → ✅ suitable

Result:
The 500W drill can be safely used with a 12V / 60Ah battery and a 2000W inverter.

This method can be used to check other devices as well.

How to choose the right battery for the inverter
Operating time = Voltage (U) × Battery capacity (Ah) × 0.8 × 0.9 ÷ Power (W)

Example:
A 12V / 50Ah battery powers a 100W light bulb at 220V:

Operating time = 12V × 50Ah × 0.8 × 0.9 ÷ 100W = 4.32 hours

Note:

  • 0.8 = Battery discharge factor (constant)

  • 0.9 = Inverter efficiency (constant)

Jak vybrat správný měnič
Při výběru měniče je třeba věnovat pozornost jak trvalému výkonu, tak špičkovému výkonu.

Trvalý výkon měniče musí být vyšší než jmenovitý výkon připojeného zařízení.
Některé indukční zátěže (např. elektrické nářadí, klimatizace, lednice) však vyžadují při startu výrazně vyšší výkon – obvykle 3 až 12násobek jejich jmenovitého výkonu.
V těchto případech musí být špičkový výkon měniče vyšší než startovací výkon zařízení, aby bylo zajištěno bezpečné používání.

Příklad:
Otázka:
Lze použít měnič 2000W s ruční vrtačkou 500W napájenou baterií 12V / 60Ah?

  1. Výpočet maximálního výkonu baterie:
    12V × 60Ah × 0,8 = 576W > 500W → ✅ dostačující

  2. Určení typu zařízení:
    Vrtačka je indukční zařízení → musí být zohledněn startovací proud.

  3. Porovnání trvalého výkonu:
    Jmenovitý výkon vrtačky je 500W,
    měnič 2000W má trvalý výkon 1000W → 1000W > 500W → ✅ dostačující

  4. Výpočet startovacího výkonu:
    Typicky cca 3 × 500W = 1500W
    Špičkový výkon měniče je 2000W → 2000W > 1500W → ✅ vhodné

Výsledek:
Vrtačku 500W lze bezpečně používat s baterií 12V / 60Ah a měničem 2000W.

Tento postup lze použít i pro kontrolu dalších zařízení.

Jak vybrat správnou baterii k měniči
Provozní doba = Napětí (U) × Kapacita baterie (Ah) × 0,8 × 0,9 ÷ Výkon (W)

Příklad:
Baterie 12V / 50Ah napájí 100W žárovku na 220V:

Provozní doba = 12V × 50Ah × 0,8 × 0,9 ÷ 100W = 4,32 hodiny

Poznámka:

  • 0,8 = Faktor vybití baterie (konstantní)

  • 0,9 = Účinnost měniče (konstantní)

Cute for a puppy or small dog- not meant for chewers
Color: Octopus Purple & Blue, Color: Octopus Purple & Blue
I bought this cute squid two-pack as Christmas toys for two dogs, and they’re absolutely adorable. The colors are bright and fun, and the crinkle sound inside is very appealing especially to the puppy I was buying for. They are a little smaller than I expected, but I added a photo with my hand in it for size reference. The size ended up being perfect for our 12-week-old Irish Setter/Golden Retriever mix. He loves grabbing the tentacles and flinging it around. It’s easy for him to hold, shake, and carry, which makes it a great puppy toy. I also have a German Shorthaired Pointer, and it’s definitely not big enough or sturdy enough for her, she doesn’t really play with it. But for a puppy or small dog, it’s ideal. The Tupac is ideal, but losing one star just for durability and size.

Lasted longer than I expected! But Still going...
Color: Octopus Yellow & Green
My dog was hesitant at first, which was strange because he loves the squeaker toys. would smell them and then walk away (I think it had a manufacturing smell) but after a few hours of airing out the fight (Playing) was on! Lasted longer than I expected! the squeak was gone from one of them but somehow, he managed to get it working again. normally he would chew the guts out to get to the squeaking piece, but they are surprisingly both still in tacked! and also, he refuses to share with his big brother even though he has two of them!

Another one bites the dust!
Color: Octopus Purple & Blue
Good toy, but nothing spectacular. Took my 10 month old girl less than a day to kill the squeaker lol. Item is still intact meaning its not shredded but once squeaker dies she's pretty much done with it.

My dog's obsession
Color: Octopus Yellow & Green
My dog has been obsessed with these since he was a puppy. I started buying them in 6 packs. He chews is after each meal like dental floss and it's always soggy and gross. I keep an eye on the legs and throw it away when he begins to chew through them. One lasts him a couple months (80 pound Lab).
