Switch to an MPPT charge controller. As @Rednecktek suggests, connect the 14.4V car charger directly to the battery. The BMS will protect the battery.

I always wondered why Montek haven't continued to build portable power stations? I had an email conversation with them many moons ago re future products but they eventually stopped responding. I thought they had the potential to build on the success of the Montek 1000.

I would suggest reaching out to customer services via email or Twitter for a resolution. I don't own an EcoFlow unit, but I think it needs WiFi connection before pairing via Bluetooth. I may be wrong though...

When using Renogy's MPPT Boost CC I experienced many issues with the BT-2 bluetooth module and the Renogy app. The app was - if I'm being honest - pretty pathetic (considering the standard of apps available from other manufacturers). The bluetooth connection regularly lost connection, making it...

I'm sorry to hear the issues you're facing with your Delta Max. In response to your first question, I have heard and received a number of complaints from my viewers re EcoFlow after-sales customer service. Whilst it's important to remember that the quality of customer service can vary between...

One of my viewers reported a similar experience. Customer service has been non-responsive. I understand some units naturally develop issues despite QC. I get that. But nothing can be more frustrating than spending hundreds if not thousands on a product, only for the support to leave you hanging...

I'd be on to customer services right away. Keep trying to get through via email/social media. Best of luck.

AllPowers have certainly been around in the power station marketplace for some time. But there have been notable concerns regarding the quality of their products and customer service. A majority of their units, including the Monster series, have proven unreliable and known to have multiple...

All best wishes mate. Stay safe. Stay green.

I have the Jackery 2000 Pro. Robust unit, though Jackery remain loyal to Lithium NMC chemistry cells. Solar setup can be cumbersome. I have a review with pros and cons of the unit (see below). I'm on no position to comment on the EcoFlow Delta 2 Max or Bluetti AC200 MAX as I have no experience...

There are a number of power stations available in the 2000-3000Wh category. My advice would be to stick to brands with a reputation of good build quality and customer service. I would happily pay a bit more for the added peace of mind of a reputable manufacturer with a track record of standing...

If you ship to the UK, I'd be interested in evaluating a unit on my YouTube channel. I have some recommendations too. I believe these suggestions can help improve the unit further.

Have you emailed Jackery re the BMS? Perhaps they can shed some light on a) the BMS and b) how to resolve the issue at hand. Techman

I've uploaded my evaluation, pros and cons of the Jackery 2000 Pro today. I discuss the DC8020 connector and the challenges that come with it. There are also a few suggestions at the end which I have forwarded to Jackery too.

It may be difficult to get 300W as there is a current limit of 8A. You may be able to get a bit over 200W but I'd imagine that's just about it. I'm now curious as to how much you can push into the EB55. I'm away for a few weeks, but when I return I may experiment max input at various voltages on...

To achieve close to 200W solar, you pretty much need 25V and above. I got 192W from a 24V LiFePo4 battery. The issue with solar panels is that the Bluetti drops solar voltage down to 17-18v. Hence, I was only able to get 130-140W from 2x 100W Solar Saga panels in parallel. I discuss this in my...

Good job @watchdoc. Thanks for sharing.

Hi, I wish Jackery had opted for a ubiquitous connector like Anderson PowerPoles. The older E1000 came houses APP for solar input. Until we see DC8020 cables/adapters available in various forms, MC4-DC7909-DC8020 is pretty much the best option available. In terms of solar charging, do both the...

Hi @Ely As far as I'm aware, there is no option to keep the display on. It's one of the biggest disappointments of the unit. I can't quite understand what Anker were thinking! You're right about the Jackery 2000 Pro - double tap the display button to keep the screen 'always on,' although it...

Hi, I haven't been able to source a compatible cable with a DC8020 pin for use with my 2000 Pro. I have used my residential panels with MC4-APP, APP to DC7909 and then DC7909-DC8020 (included in the box). I'm waiting for an APP-DC7909 adapter to arrive, so for the time being I'm stuck with...

Hey James, You'd want to connect a solar panel direct to the Jackery. As you rightly mentioned, the E500 has an MPPT charge controller built in to the unit. If you absolutely must use the ZAMP, I'd personally go with ATP to Anderson PP, then APP to DC7909 connector, something like this. But...

No worries bud, happy to help. As @Ely mentioned Jackery are a good starting point. Work right out of the box. But do check out other reputable manufacturers too. All the best ;) Techman

Since you're looking for a potable power station with an approx. 1500Wh capacity, I would advise not to cut corners with cheaply made units with low quality components. If you want your power station to last a long time, purchase from a reputable brand with a track record of good products and...

Jackery have a 15% off site-wide sale. Also avaialble on Amazon US. CA, UK, and DE. Good opportunity to save on Jackery portable power stations/solar panels. Offer available 18-20 October 2021. Techman

If it helps, I've found an adapter (DC jack) that fits the 6.5 x 1`.4mm DC output port. If you have a set of laptop DC adapters usually included with portable laptop chargers it's the DC adapter marked 'A' on the side. Similar to the 'A' adapter in the set here. Here's my take on the Explorer...

The E240 can take 12-30v at 3.5A max. I don't personally have an E240 but judging from my experience with my Explorer 500 and mate's Explorer 1000 they take in more amps at 22-24v range. A bit of a bummer when most 18v solar panels (including Jackery's own solar saga series) output between...

Ever since purchasing an Omnicharge Omni20+ powerbank I've been suggesting this sort of feature to manufacturers such as Bluetti. EcoFlow, Jackery and Leoch amongst others. The response I get is 'We'll consider this in future products.' The Omni 20+ has a user-adjustable DC voltage DC 5.5x2.1mm...

Spot on and good answer. Yes, the internal LiFePo4 batteries may last 3000+ cycles (longer if cycled to 80-90% SOC) but it is arguably misleading when manufacturers promote 3000+ life cycles on the units themselves. I would like to see manufacturers offer a 3-year warranty on components and 5+...

EB150 specs suggest 16-60v DC input, hence no reason why it shouldn't work. Reverse polarity/MC4 to 8mm cable would be my first thought but with these ruled out it's frustrating MaxOak are not actively helping to resolve the issue at hand. Personally I had little support from PowerOak (Bluetti's...

Yep - Boost charge = absorbtion in EPEver charge controllers

Weight comparison with the new AC200 Max somewhat gives it away, but they do state "No Battery Inside." Kinda expensive for just a modular hub unit.

You'll find you can purchase large quantity of products from some manufacturers on Alibaba with the option to rebrand it to whatever you like. In fact there are plenty of portable power stations (aka solar generators) on Amazon/webstores that are shipped in standard brown boxes with almost no...

I see no reason why car charging should be an issue. If it could cause damage, they should explain how. My personal experience with customer service of some of these manufacturers [including PowerOak (same as Bluetti)] is that sometimes they a) don't have a clue or b) do not fully understand...

I'm not sure if available in the US but another DC-DC option would be a Powertraveller Powergorilla. In a nutshell it is a multi-voltage powerbank, though I must admit a bit pricey. It can output @24v, supports daisy chain/pass-through charging and has a built-in MPPT charge controller for solar...

Greetings from a fellow UK member! Forgive me but I fail to understand what your question is? As for the DC-DC charging option and the car charger linked in your post, it clearly states 84W max output at 3.5A. Sure it will charge the EB150 but at snail's pace. Using the original power brick...
