Specs:
The typical value proposition of these large-capacity portable battery banks revolve around the "I hate dealing with gasoline/natural gas canisters, engine oil (required to run most gas generators, which are frequently sold without any), noise (gas generators are not quiet by design), and weight (DAE LIFT WEIGHTS!?!??!?)".
Having that said, I recognize the "leading lead acid competitor": it's the Goal Zero Yeti 1250, and having been on the market for quite some time, its performance characteristics are well-known. While browsing Amazon though I came across this non-SLA "gas generator". Notice the front panel with the 12V and USB outlets? That's a carbon copy of what was demoed on the Grengine, the difference is that the AC inverter outlets are on the side instead of being situated left of the panel.
*looks further down* Oh shit... Grengine Ultra Lite is a literal clone of what I just linked! This is an Alibaba resell! Then again, this is IGG, where reselling existing products is always a thing. Also the pricing for their Ultra Lite is $599 plus shipping. Er guys? These are already being sold on Amazon for just 400 bucks shipped!
Another thing about these battery-based "generators" is the user needs to get their feet dirty in solar panels and the like in order to get the most out of these heavy power banks. In other words, this isn't a battery pack, it's a long-term commitment into off-grid power and that $1450 price (for the full-size unit) is just a down-payment!
In a power blackout situation, I'd much rather have a gas generator instead.
Yes, When I had my EV I would drive under 50 miles almost every day.
Regarding the product i couldn't find a data sheet or specifications on your website.
That said from photos, and comments here, it appears to be a 5kWh external battery pack, able to be charged from a standard wall outlet (using a tiny wall wart), and with an integrated inverter powerful enough to run a factory volt EVSE (I assume something like 15A at 110V?)
Your website shows a slim female carrying the device with one hand, and you advertise the price as USD999. You state on reddit the current charge time from a wall outlet is 6 hours.
There are a few technical issues with the above that you really should look into.
Weight As an example, the chevy bolt battery pack holds 60kWh, and weights 440kg. Your pack is to be 12 times smaller, so weight will be at least 37 kg (prob more as packaging in a smaller pack will be less efficient. A 2kW inverter will be 5 - 8 kg, therefore your minimum weight will be 42 - 45kg's. No way your slim female is carrying that with one hand wearing heels.
Cost A 6.4kWh powerwall runs as USD3000. Your price is under a third of that, and you need to include an inverter & charger that will run to hundreds of dollars...
Wall Wart To charge in 6 hours, you will need to charge at 830Watts. I don't think any wall wart goes that high.
-------------------------------------------------
Take a look at what is already on the market:
0.4kWh, 300W output battery bank for USD390, 12.36 pounds
Anker 0.4kWh, USD500, 9.36 pounds
1.1kWh, 1100W output, USD1,749, 20 pounds
You specs require something about 10 to 12 times the capacity / inverter power as the first two items, and about 5 times the capacity / inverter power of the last one.
As such I would expect you would need to price your device at around USD 6000, and expect it to weigh 100pounds (roughly 50kg).
With those numbers the proposal is a lot less attractive. 50kg's is very hard to move by hand, and $6000 is a lot of money to tie up in a battery bank. (I wouldn't want to leave that unattended as I charged during the day). Also that money would go a long way in terms of just buying a longer range EV in the first place (Price jump from a 30kWh Leaf to a 60kWh Chevy Bolt in the USA is $6000) and that buys you a 6x the additional range of your 5kWh power pack, with convenance to boot... (no charging car and power pack each night (just charge car), no lugging around heavy power pack. no need to change except at night (every second night) for your 40/ 50 mile days)...
I use a solar generator like this
Then I use a solar panel to recharge it. This battery will run my fridge for a few days plus other items.
They make cheaper ones though like this
That could also be hooked up to a portable solar panel for recharge.
I have one of these. i scored it on ebay for less than $300 us.
It seems to run my Dometic fridge for about a day or two.
I have charged my laptop from it a few times in a jam, but it uses way more power than my fridge.
It also has a built in solar controller which i am going to hook up a renogy suitcase.
