Zeus A8000-48V 8kW J180 4" Alternator with Isolated Ground
The ARCO Zeus A8000-48V alternator turns on at lower RPMs, runs cooler, and provides more power than other 48V alternators that are larger and heavier. This alternator continuously generates over 3kW (55 Amps)at 2,500 RPM and almost 6kW (111 Amps) at 4,000 Alternator RPM. Put in real-world terms, a marine diesel engine charging at 1,200 RPM with a 3.13:1 pulley ratio is generating just over 5kW (97 Amps), and a Mercedes Sprinter at 750 RPM with a 3.21:1 ratio is generating over 3kW (55 Amps)!
Instead of using rotors designed for 48 volts, many competitor alternators simply use their 12V rotors which is less efficient and limits output at all RPMs. In this scenario, your external smart regulator must drastically reduce field, by as much as 78%. If this is not done correctly, you run the risk of destroying the unit and damaging other components in your system. ARCO utilizes a native 48V rotor and field current. This results in our 48V alternator running cooler than competitor’s 48V alternators, having a direct impact on the alternator’s lifespan.

Love this book!
Format: Paperback
This is my first time reading a book from this author, and it’s safe to say, I will be reading again! I love the chaos of the twitter war while they are simultaneously falling in love with eachother! This is a fluffy, kicking-your-feet while reading book. This is definitely a slow burn though, I had a little trouble getting into it, but had me hooked a few chapters in! If you are looking for the cutest YA- book, this is it

Very Cute & Fast Read
Format: Hardcover
This was very cute and I read it in almost one sitting. It isn’t a new favorite, but I would read it again and plan on reading Emma Lord’s next book.
Pepper and Jack were both great characters. They were well-developed and likable, but flawed. And I definitely connected with Pepper. This took me back to the stress of high school. They both had complexity and felt like real teenagers.
Honestly, before I read this, I was very unsure of the reality of two teens running a company Twitter accounts. But Ms. Lord did a good job making me believe how this happened. And I think it is important to remember there are real human beings behind the handle.
Beyond the tweets, there were a lot of textual conversations. That is one of my favorite things to read in a book. And these were incredibly adorable. They made me smile and were some of my favorite parts to read.
The romance was cute and well-developed. I liked that Pepper and Jack really were becoming friends before becoming a couple. And I thought the conflicts/issues would go a certain way, but they didn’t. I liked being kept on my toes. It also felt organic and like a healthy relationship.
There were other relationships, too. Some were more developed than others, but I appreciate the layers. The changing relationship between Pepper and Pooja was beautiful. We stan solid female friendships in this house.
Speaking of little things: the LGBT+ rep. I loved it! Yes, it’s side characters, but that’s fine. I loved how much of a non-issue it was. Yes, there are still bigots in the world, but I’m team be the change you wish to see in the world. So, I like a book where characters are just living their lives and no one (adult or teen) cares. That’s the world I want to live in.
Ok, this review has gone on longer than I expected. Tweet Cute was such a fun and (fairly) light read. Ms. Lord addressed some serious issues teens face, but it never felt too dramatic. My already anxious mind really appreciated that tone choice. And I’m definitely excited to read another Emma Lord book.

Review - Tweet Cute
Format: Hardcover, Format: Hardcover
**Disclaimer: I was given a free e-ARC of the below in exchange for an honest review from NetGalley**
Title Tweet Cute
Author Emma Lord
Release Date January 21, 2020
Description from Amazon
Meet Pepper, swim team captain, chronic overachiever, and all-around perfectionist. Her family may be falling apart, but their massive fast-food chain is booming ― mainly thanks to Pepper, who is barely managing to juggle real life while secretly running Big League Burger’s massive Twitter account.
Enter Jack, class clown and constant thorn in Pepper’s side. When he isn’t trying to duck out of his obscenely popular twin’s shadow, he’s busy working in his family’s deli. His relationship with the business that holds his future might be love/hate, but when Big League Burger steals his grandma’s iconic grilled cheese recipe, he’ll do whatever it takes to take them down, one tweet at a time.
All’s fair in love and cheese ― that is, until Pepper and Jack’s spat turns into a viral Twitter war. Little do they know, while they’re publicly duking it out with snarky memes and retweet battles, they’re also falling for each other in real life ― on an anonymous chat app Jack built.
As their relationship deepens and their online shenanigans escalate ― people on the internet are shipping them?? ― their battle gets more and more personal, until even these two rivals can’t ignore they were destined for the most unexpected, awkward, all-the-feels romance that neither of them expected.
Initial Thoughts
Ok, can I just take a minute to talk about the fact that I’m reviewing a book that’s coming out in 2020?!? Seriously, where did the year go? It feels like just yesterday I didn’t even know what an ARC was, and now, I’m reviewing books for 2020! Anyway, I was chosen for a Blog Tour of this book in January but I couldn’t resist reading it early and writing this review.
Some Things I Liked
Gossip Girl vibes. I. Love. Gossip Girl. This book had all the best parts of that story without any of the needless bitchy-ness. I loved that. And, it was self-referencing (in a way). The story cited its parallels to the hit show and I just loved that.
Additionally, I loved all of the references to various bits of pop culture.
Alternating POV. This was perfectly done. Since our main characters are both harboring secrets that the other doesn’t know, the POVs made this story so much more fun to follow.
Grilled Cheese. Buddy the Elf’s food groups are candy, candy canes, candy corns, and syrup. Mine are grilled cheese, mac and cheese, donuts, and peanut butter cups. This whole story revolved around one of the most epic foods in existence.
I also really enjoyed the multi-generational element in both of these rivaling restaurants.
Favorite Quote
“Full-time vice principal and part-time thief of joy.”
“Thief of joy” is one of my favorite things that Michael calls Dwight on The Office. When I saw it used here, I literally laughed out loud.
Final Thoughts
This book was adorable. I loved every page. I applied for it kind of on a whim since I really don’t read many contemporary novels but this really caught my eye. I’m so excited to be participating in the blog tour in a few months.
In the meantime, ADD THIS TO YOUR TBR, like ASAP (or as Michael Scott would say, ASA P as possible 😉).
⭐⭐⭐⭐⭐
